General Electrical System - Repair - e92/93 BMW M3 E90

Battery care and maintenance

In low-maintenance batteries, check the acid level at least once a year. If necessary, top up with distilled water up to the top marking.

The increasing number of electronic control units in the car reduces the self-discharging time of the battery (even in standby mode). To maintain the battery service life and to avoid exhaustive discharging, recharge laid-up vehicles every 6 weeks at the latest.

Battery test

The battery acid density can be used to measure the charge state. However this test produces uncertainty caused by a design-related range of variation. The acid density e.g. for a charged battery is 1.28 kg/l (in the tropical version the acid density is 1.23 kg/l).

Another interference factor is the acid lamination immediately after filling with distilled water.

Battery wear with partially sulfated and/or heavily contaminated plates will also lead to incorrect acid density test results.

61 00 ... Diagnosis for Condition Based Service

Note. Red symbol for pre-delivery check

The vehicle is coded at the end of the assembly line so that the red symbol for the pre-delivery check is shown in the Next Service display (same symbol as vehicle check).

The symbol is a reminder to the Service staff that the predelivery check has not yet been carried out on this car.

Note. Do not carry out a reset.

Do not confuse this function with the "Vehicle check" maintenance scope.

Do not carry out a reset via the instrument cluster.

When carrying out the pre-delivery check with the "Transport Mode/Pre-delivery check" service function

The symbol is automatically removed from the display after the service function has been executed.

Scheme 2

KEY SPECIFICATION CHART

4 service functions are available in the BMW diagnosis system for maintenance

1. Transport Mode/Pre-delivery check
2. CBS Correction Tester Data
3. Reset CBS
4. CBS Correction Vehicle Data

Service function: Transport Mode/Pre-delivery check

To be able to hand over a vehicle to the customer in proper working order, it is essential to execute the "Transport Mode/Pre-delivery check" service function.

The following items are worked through during the pre-delivery check

1. Deactivation of transport mode.
2. An adaptation process must be activated in order to determine the vehicle-specific mileage/kilometrage per week. Transport and immobilization periods before the vehicle is delivered to the customer therefore have no effect on the customer-specific weekly mileage/kilometrage. The weekly mileage/kilometrage is used to control escalation from "green" to "yellow" (approx. 4 weeks before "red") for maintenance scopes with remaining distances. The averaged mileage/kilometrage of the last 6 weeks is taken into account here.
3. Coding or blanking out of the legally prescribed intervals for the statutory vehicle inspection and statutory exhaust emissions test.
4. Input of the target dates for the statutory vehicle inspection and the statutory exhaust emissions test (automatic or manual). Automatic: By input of the date of first registration and of the time interval Manual: By direct input of the target date
5. Entry of local, service-related phone numbers, depending on vehicle equipment specification (e.g. BMW Group Mobile Service, BMW Hotline, customer's home dealer). The country-specific phone numbers are displayed in the BMW diagnosis system as a reference text. The phone numbers can simply be read off during the input prompt.
6. Reference to initialization of TeleService, depending on vehicle equipment specification.
7. Checking and if necessary setting of the on-board date for the vehicle.
8. Entry of the date for first registration of the vehicle.
9. Now clear the fault memory.

Note. Reducing input expenditure.

Standardized data are stored in the BMW diagnosis system (for repeated use) in the interests of minimizing the time spent on making inputs in the garage/workshop. The standardized data can be changed with the "CBS Correction Tester Data" service function.

Service function: CBS Correction Tester Data

Data are automatically stored in the vehicle with the "Pre-delivery check" service function.

The standardized data can be changed with the "CBS Correction Tester Data" service function.

The following standardized data can be changed

1. Phone numbers: BMW Group Mobile Service BMW Hotline Customer's home dealer The country-specific phone numbers are contained as reference texts in the BMW diagnosis system (read off during the input prompt). The phone numbers must be input with the international dialling code.
2. Legally prescribed vehicle inspection (country-specific): Coding or blanking out Interval for calculating the target date The target date is calculated on the basis of the date of first registration.
3. Legally prescribed exhaust emissions test (country-specific): Coding or blanking out Interval for calculating the target date The target date is calculated on the basis of the date of first registration.

Note. Automatic function after installation of the BMW diagnosis system.

The standardized data are automatically established when the pre-delivery check is carried out for the first time. It is therefore not necessary to input the data separately.

Service function: Reset CBS Condition Based Service

A maintenance scope can be reset with the "Reset CBS Condition Based Service" service function. Even when availability is over 80 %.

The benefit of reset via the BMW diagnosis system is that the on-board date is corrected automatically.

The individual maintenance scopes are displayed in the BMW diagnosis system with service counter and availability.

1. The service counter is reset by one counter on resetting. All service counters are set to "1" on new vehicles. The service counters are used in the Service Acceptance/Reception Module (SAM) on a scope-specific basis for controlling additional work.
2. Availability is set to 100 % on resetting. Availability in % is the wear value of the maintenance scope. The greater the availability, the longer it is to the next maintenance scope. 0 % means that the maintenance measure must be carried out.

Service function: CBS Correction Vehicle Data

Once this service function has been executed, it is no longer possible to reconstruct the previous status.

The "CBS Correction Vehicle Data" service function is available if a reset has been carried out erroneously. In this way, the availability of a maintenance scope can be corrected to a realistic value.

A data or a mileage/kilometer reading is entered for correction. These data are converted internally into an availability in %. In so doing, the BMW diagnosis system only accepts a smaller value as the current reading in the control unit. In addition, the service counter of the scope is automatically reduced by one counter.

The inputs are used in the Service Booklet to determine the realistic availability. A realistic availability can be reconstructed on a scope-specific basis by means of the last maintenance measure (with mileage/km reading and date).

This does not include correcting the availability for brake pads. The brake pad residual thickness must be measured and input (in millimeters).

Note. Reference for distance- and time-dependent maintenance scopes

For a correction, the availability is referred to the distance- and time-dependent calculation.

61 00 ... Safety instructions for handling vehicle battery

Battery acid is highly corrosive

Do not allow any battery acid to come into contact with the eyes, the skin or clothing. Therefore wear protective clothing, gloves and goggles.

Do not tilt the battery, acid may emerge from the vent opening.

In event of contact with acid

If acid is splashed into the eyes, rinse them immediately for several minutes with clear water. You must then consult a doctor without delay.

If acid is splashed onto the skin or clothing, neutralize it immediately with a soapy solution and rinse with lots of water.

Seek medical attention immediately if battery acid is accidentally swallowed.

Explosion hazard

Strictly no flames, sparks, naked light or smoking!

A highly explosive mixture of electrolytic gas is created when batteries are charged. The rooms where charging is carried out must therefore always be well ventilated.

Avoid the formation of sparks when handling cables, wiring and electrical devices.

Turn the ignition lock to the 0 position before disconnecting or connecting the battery.

Do not place tools or any similar object on the battery (danger of short-circuiting and explosion!).

In general

To avoid damage, observe the following instructions

1. Avoid compressive and tensile loads
2. Make sure cables are laid without kinks or abrasions
3. Ensure non-contacting routing at sharp-edged body parts; use muckets if necessary
4. Secure additionally laid cables/leads with cable ties

61 12 ... General information on intelligent battery sensor (IBS)

Note. Do not connect continuous trickle charger to the cigarette lighter.

The cigarette lighter is powered by the rear distribution box via a relay. This relay drops out after terminal 15 OFF. This means that a continuous trickle charger connected to the cigarette lighter is disconnected from the battery.

Charge the battery via the jump-start connection points. Only then can the power supply be registered by the vehicle.

1. Do not introduce any additional connections at the battery negative terminal.
2. Do not modify the grounding cable. The grounding cable also serves to dissipate heat.
3. Do not establish any connection between the IBS and the sensor screw.
4. Do not use force when disconnecting the pole shoe from the battery terminal: Do not pull on the grounding cable. Do not place any tools under the IBS to lever off the pole shoe.
5. Do not use IBS connections as levers.
6. Use a torque wrench and set tightening torque in accordance with repair instructions.
7. Do not release or tighten down sensor screw (screw with Torx head).
8. Avoid contact between IBS and ground.

1. The IBS and the cables can be destroyed by mechanical strain when the battery is replaced. Therefore avoid mechanical strain.
2. The size (capacity) of the battery required for the car is coded in the Car Access System (CAS).
3. Use the battery size (capacity) installed as standard when replacing the battery.
4. Register battery change via Service Function (Progman or DIS).
5. Delete fault entries in the Digital Engine Electronics (DME) associated with battery replacement.
6. Always proceed in accordance with the repair instructions.

Note. Battery draining possible in spite of the intelligent battery sensor IBS being fault-free.

1. A battery can be drained (e.g. with lights or radio switched on) even when the IBS functions perfectly in conjunction with power management.
2. For this reason, only replace the IBS when a corresponding fault is entered in the DME or DDE.

12 00 ... Instructions for disconnecting and connecting battery

Observe safety instructions for handling vehicle battery .

Before disconnecting battery

Turn off the ignition and other electrical loads/consumers to prevent sparking when reconnecting.

Note. If the ignition is not turned off when the battery is disconnected, fault memories may be set in some control units.

General notes on disconnecting battery

1. Do not disconnect battery leads and leads from alternator and starter motor while engine is running.
2. Cars with IBS on battery negative terminal: Do not under any circumstances pull/lever off pole shoes by force. Do not under any circumstances release socket-head cap screw of IBS.
3. Detach terminal of battery negative lead from car battery and second battery if fitted. Cover battery negative terminal(s) and secure.
4. When work is carried out on the electrical system, faults may be caused in the fault memories of some control units when the battery is connected.
5. When installing battery terminal: Tightening torque, see 61 21 1AZ in «61 21 BATTERY WITH TERMINAL»(/bmw/m3/e90-2007-2013/remont/door-locks-anti-theft-systems/#general-electrical-system-tightening-torques-e9293__61-21-battery-with-terminal) .

After connecting battery

Vehicles with a two-battery system

Starter and equipment batteries

A two-battery system has a starter battery circuit and an equipment battery circuit. A supplementary control unit monitors both battery circuits. Depending on the situation, the battery circuits are connected to or isolated from the supplementary control unit via an isolating relay.

Two AGM batteries, whose design and properties are described in AGM batteries, are used as a storage battery.

Receiving/giving starting assistance via jump start terminal

The engine can be jump-started with an external voltage supply via the jump start terminal on the right side of the engine compartment.

Note. The starter battery is isolated from the alternators when the engine hood/bonnet is open.

Giving starting assistance via the jump start terminal is thus limited by the capacity of the starter battery when the engine hood/bonnet is open.

Charging starter and equipment batteries via jump start terminal

The starter battery is charged as a matter of priority with a charger connected to the jump start terminal. The voltage at the starter battery is the decisive factor in determining whether the equipment battery is also included in the charging operation. The supplementary control unit automatically detects a charging operation at a charging voltage at the starter battery of > or = 13.5 V. The isolating relay is closed and thus the equipment battery is connected in parallel. Both batteries are now charged.

Prerequisite

1. Terminal 61 inactive
2. Terminal 15 inactive

If terminal 15 becomes "active" during the charging operation, the isolating relay is opened immediately and again only the starter battery is charged.

Note. When the engine hood is open, the isolating relay is also opened in normal operation when the engine is running. A special mode can be set by means of diagnosis for workshop/garage operation. The isolating relay is closed from terminal R in this operating mode. This mode is automatically reset once a distance of 5 km has been driven.

Trickle charging

The increased closed-circuit current consumption can be compensated for via the jump-start connection point with the aid of the "Acctiva easy" battery trickle charger (Service Information 2 03 05 205 ).

12 00 ... Notes/information on start assistance (jump starting)

Do not start the engine with help of starting sprays.

Preparation

Conform with the following when starting the engine with a jump starting cable.

1. Ensure that the jump starting cable wires are of appropriate cross-section size.
2. Only use fuse-protected jump starting cables.
3. Check whether the current-supplying battery has 12 V voltage.
4. If the engine is started from the battery of another vehicle, ensure that there is no contact between the bodies of both vehicles.

If the battery in the vehicle supplying power is weak, start the engine of this vehicle and let it run at idling speed.

Operation

It is essential to conform to the procedures so as to avoid injury to persons or damage to parts.

1. Automatic transmission: select drive position "P", apply parking brake.
2. Manual transmission: move gear lever to neutral position, apply parking brake.
3. Ensure that the jump leads cannot get caught in rotating parts, e.g. fan.
4. First connect both positive poles of the batteries with one jump starting cable (red).
5. Use the battery positive terminal in the engine compartment for vehicles with the battery in the luggage compartment.
6. Then use the second jump starting cable (black) to connect the negative post of the current-supplying battery with the earth/ground point (not the negative pole or the body) of the vehicle to be started.

Risk of explosion!

After the engine of the vehicle to be started has fired, first disconnect the jump starting cable between the negative pole and the earth/ground point. Then remove the starting cable from the positive poles.

In low-maintenance batteries, check the acid level at least once a year. If necessary, top up with distilled water up to the top marking.

The increasing number of electronic control units in the car reduces the self-discharging time of the battery (even in standby mode). To maintain the battery service life and to avoid exhaustive discharging, recharge laid-up vehicles every 6 weeks at the latest. The time for self-discharging depends on vehicle type and equipment specification.

The battery acid density can be used to measure the charge state. However this test produces uncertainty caused by a design-related range of variation. The acid density e.g. for a charged battery is 1.28 kg/l (in the tropical version the acid density is 1.23 kg/l).

Another interference factor is the acid lamination immediately after filling with distilled water.

Battery wear with partially sulfated and/or heavily contaminated plates will also lead to incorrect acid density test results.

Safety regulations

Safety regulations for handling components of airbag system. See 72 00 ... SAFETY REGULATIONS FOR HANDLING COMPONENTS WITH GAS GENERATORS .

Instructions for disconnecting and connecting battery.

In event of non-visible damage to wiring harness

Disconnect plug connection on airbag module or on adapter plug. It is absolutely vital to disconnect the contacts in succession as there is a risk of them being mixed up! Cut through one cable after the other at an appropriate position, do not under any circumstances cut through both cables at the same time. Insulate cables remaining in wiring harness with insulating tape. Now disconnect plug connection on airbag control unit. Unpin contacts. Cut through one cable after the other at an appropriate position and insulate with insulating tape, do not under any circumstances cut through both cables at the same time. Pin contacts of repair cable for airbag control unit in control unit plug, assignment of repair cables is relevant. Lay repair cable in car parallel to existing airbag lead. Now pin in contacts for airbag control unit or contacts of adapter plug, assignment of repair cables is relevant. Cut off excess length of repair cable in proximity (visible area) of airbag module or of adapter plug. Twist open cables. With the connectors and shrink-fit hoses in the Electronic Parts Catalogue (EPC), reconnect the cables with the same cable colors. Twist cables again, open length (twist) must not exceed 40 mm. Secure interface (shrink-fit hoses) with insulating tape to prevent cables from twisting open.

In event of visible damage

Expose cable at damaged areas. Cut through one cable after the other at an appropriate position and insulate cables no longer required in wiring harness with insulating tape, do not under any circumstances cut through both cables at the same time. Now, depending on the scope of work, unpin contacts either on airbag control unit/airbag module or on adapter plug. Cut off unpinned cables. Insulate cables remaining in wiring harness with insulating tape. Now pin in contacts of repair cable, assignment of repair cables is relevant. Lay repair lead in car parallel to existing airbag lead up to cutting point. Cut off excess length of repair lead. Twist open cables. Connect cables with connectors and shrink-fit hoses in Electronic Parts Catalogue (EPC), assignment of repair cables is relevant. Twist cables again, open length (twist) must not exceed 40 mm. Secure interface (shrink-fit hoses) with insulating tape to prevent cables from twisting open.

Battery acid is highly corrosive

Do not allow any battery acid to come into contact with the eyes, the skin or clothing. Therefore wear protective clothing, gloves and goggles.

Do not tilt the battery, acid may emerge from the vent opening.

In event of contact with acid

If acid is splashed into the eyes, rinse them immediately for several minutes with clear water. You must then consult a doctor without delay.

If acid is splashed onto the skin or clothing, neutralize it immediately with a soapy solution and rinse with lots of water.

Seek medical attention immediately if battery acid is accidentally swallowed.

Explosion hazard

Strictly no flames, sparks, naked light or smoking!

A highly explosive mixture of electrolytic gas is created when batteries are charged. The rooms where charging is carried out must therefore always be well ventilated.

Avoid the formation of sparks when handling cables, wiring and electrical devices.

Turn the ignition lock to the 0 position before disconnecting or connecting the battery.

Do not place tools or any similar object on the battery (danger of short-circuiting and explosion!).

Note. Do not connect continuous trickle charger to the cigarette lighter.

The cigarette lighter is powered by the rear distribution box via a relay. This relay drops out after terminal 15 OFF. This means that a continuous trickle charger connected to the cigarette lighter is disconnected from the battery.

Charge the battery via the jump-start connection points. Only then can the power supply be registered by the vehicle.

1. Do not introduce any additional connections at the battery negative terminal.
2. Do not modify the grounding cable. The grounding cable also serves to dissipate heat.
3. Do not establish any connection between the IBS and the sensor screw.
4. Do not use force when disconnecting the pole shoe from the battery terminal: Do not pull on the grounding cable. Do not place any tools under the IBS to lever off the pole shoe.
5. Do not use IBS connections as levers.
6. Use a torque wrench and set tightening torque in accordance with repair instructions.
7. Do not release or tighten down sensor screw (screw with Torx head).
8. Avoid contact between IBS and ground.

1. The IBS and the cables can be destroyed by mechanical strain when the battery is replaced. Therefore avoid mechanical strain.
2. The size (capacity) of the battery required for the car is coded in the Car Access System (CAS).
3. Use the battery size (capacity) installed as standard when replacing the battery.
4. Register battery change via Service Function (Progman or DIS).
5. Delete fault entries in the Digital Engine Electronics (DME) associated with battery replacement.
6. Always proceed in accordance with the repair instructions.

Note. Battery draining possible in spite of the intelligent battery sensor IBS being fault-free.

1. A battery can be drained (e.g. with lights or radio switched on) even when the IBS functions perfectly in conjunction with power management.
2. For this reason, only replace the IBS when a corresponding fault is entered in the DME or DDE.

Introduction

In September 2002 so-called VRLA batteries, better known as AGM batteries, were introduced.

(VRLA stands for V alve R egulated L ead A cid, i.e. lead acid battery with pressure relief valve; AGM stands for A bsorbent G lass Mat, i.e. absorbent glass fibre fleece)

AGM batteries are fitted in models with electrical loads/consumers which have a high energy demand.

With the option SA 146 (2nd battery), the AGM battery (70 Ah) is fitted as the 2nd battery.

The constantly increasing energy demand of modern vehicle electrical systems calls for ever more powerful battery solutions. Today, up to 100 servomotors, which have to be electrically powered, operate in a modern luxury-class motor vehicle. Added to these are safety, environmental and comfort and convenience elements which are increasingly becoming standard features, such as e.g. Anti-lock Brake System (ABS), Dynamic Stability Control (DSC), electric steering effort assistance (EPS), heated catalytic converter, electronic chassis and suspension control, air conditioning and navigation system.

The power consumption is considerable even when the vehicle is parked.

The somewhat higher price compared with a battery of similar size is fully balanced by the following benefits

1. Significantly longer service life
2. Increased starting reliability at low temperatures
3. Safe starting of engines with high starting current demands, e.g. high-performance diesel engines
4. 100 % freedom from maintenance
5. Low risk in event of an accident (reduced risk to the environment)

Scheme 151

KEY SPECIFICATION CHART

Unlike the previously used lead calcium batteries, the sulphuric acid contained in batteries with fleece technology is not self-contained in the battery housing.

Instead, the sulphuric acid is 100 % bound up in glass fibre fleece mats (separators). Thus, no acid can escape if the battery housing is damaged. In addition, the AGM battery is sealed gas-tight. This is possible because the gases are converted back into water as a result of the separator permeability.

Brief description of components

An AGM battery can be recognized by its black housing and the lack of a so-called "Magic Eye".

Scheme 152

KEY SPECIFICATION CHART

Design

The AGM battery differs from the conventional lead calcium battery as follows

1. Larger plates: Larger plates provide for a 25 % higher power density.
2. Separators made of glass fibre fleece: These provide for up to 3 times higher cycle reliability. This in turn improves cold starting performance, current consumption and service life.
3. Gas-tight housing with pressure relief valve (see also mode of operation): The cell plugs are welded and cannot be opened.
4. Acid bound up in the glass fibre fleece: The acid is not as previously self-contained in the housing, but 100 % bound up in the glass fibre fleece. This provides increased protection against acid leakage and thus represents a reduced risk to the environment.

Mode of operation

The AGM battery differs from conventional batteries in its non-polluting and substance-retaining behaviour during charging.

When vehicle batteries are charged, the two gases oxygen and hydrogen are released by electrolysis.

1. In a conventional wet lead calcium battery, the two gases hydrogen and oxygen are dissipated into the atmosphere.
2. In an AGM battery, the two gases are converted back into water: The oxygen which is created at the positive electrode during charging passes through the permeable glass fibre fleece to the negative electrode. At the negative electrode the oxygen reacts with the arriving hydrogen ions in the electrolyte to form water (oxygen cycle).

In this way, the gas and thus also the electrolyte are not lost.

Only in the event of an excessively heavy buildup of gas, i.e. excessively high pressure buildup (20 to 200 mbar), does the pressure relief valve discharge the gas. In this process, the pressure relief valve does not allow any oxygen in the air to enter. Because a valve regulates the pressure in the battery, the AGM battery is also known as a VRLA battery (Valve Regulated Lead Acid).

Notes and instructions for service personnel

It is necessary when handling an AGM battery to observe some particular points pertaining to battery changing and installation location.

Charging

When charging removed batteries (so-called stand-alone batteries), do not exceed the maximum charging voltage of 15.2 V at room temperature. Also when charging via the jump start terminal, do not exceed the maximum charging voltage of 15.2 V at room temperature.

The AGM battery will be damaged even when it is only briefly charged with a charging voltage of more than 15.2 V. A charging voltage of more than 15.2 V is usually used in quick-charging routines.

Installation location

The AGM battery must not be installed in the engine compartment on account of the high spatial temperature differences, otherwise its service life will be significantly shortened.

Housing

The AGM battery must not be opened under any circumstances as the introduction of oxygen from the air will cause the battery to lose its chemical equilibrium and be rendered non-operational.

Battery changing

Any conventional lead calcium battery can always be replaced by an AGM battery.

Using an AGM battery does not require any alterations to be made to the vehicle electrical system.

Note. The AGM battery is recommended for "problem customers".

"Problem customers" encounter a high energy throughput through their batteries. This high energy throughput is caused by stationary loads/consumers (TV, independent heating, etc.) and a bad use profile for the battery ("chauffeur operation", short-distance driving, "stop-and-go"). The use of an AGM battery is recommended for these problem customers.

61 20 ... Battery charging

If a normal or quick charger is used to charge the battery, the battery must be disconnected from the vehicle electrical system and removed. This prevents damage to paintwork and upholstery.

If necessary, open existing plugs on the individual cells.
