SAFETY PRECAUTIONS
| WARNING | Failure to follow these instructions may result in personal injury or possible death. When performing the drive cycle operation, pay strict attention to driving conditions and observe and obey all posted speed limits. Test equipment must always be secured to the rear seat and operated by a second person. If test and measuring equipment is operated from the passenger seat, the person seated could be injured in the event of an accident involving deployment of the passenger-side airbag. The fuel system is under pressure! Before opening the fuel system, place rags around the connection area. Then release pressure by carefully loosening the connection. The engine section of the fuel system, after the high pressure pump, is under extremely high pressure! When working on engine or fuel injection system, fuel pressure must be relieved to residual pressure before opening high pressure components. Refer to the Service Information for the proper procedure. If the battery has not been disconnected, the fuel pump fuse must be removed before opening the fuel supply system as the fuel pump may be activated by the driver's door contact switch. Testing of the EVAP and ORVR systems can result in the escape of explosive fuel vapor. Do not smoke while testing the EVAP system, and make sure the area you are working in is well ventilated. Observe the following for all procedures, especially in the engine compartment due to lack of room: Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed. Watch for sufficient clearance to all moving or hot components. Do not touch or disconnect the Ignition Coils, ignition wires, connecting parts or adapter cables when the ignition is on or the engine is running or turning at starting RPM. Only disconnect and reconnect wires for injection and ignition system, including test leads, when the ignition is turned off. When removing and installing components from full or partially full fuel tanks, observe the following: The fuel tank must only be partially full. How much fuel can remain in the fuel tank may be read in the respective work description. Empty the fuel tank if necessary. Before starting work, switch on the exhaust extraction system and place an extraction hose close to the installation opening of the fuel tank to extract escaping fuel fumes. If no exhaust extraction system is available, a radial fan (as long as motor is not in air flow) with a displacement greater than 15 m 3 /h can be used. Prevent fuel from contacting the skin! Wear fuel-resistant gloves! When servicing the engine control module (ECM), it may be necessary to use a heat gun. The heat gun, shear bolts, and parts of the protective housing will become extremely hot. Use extreme caution when working with or handling these parts to avoid personal injury. Observe operating instructions when working with a heat gun. To prevent damage (burning) to the wiring and harness connections, insulation and the electronic components, perform outlined work steps exactly! The cooling system is under pressure. To avoid scalding, use caution when opening the cooling system and servicing cooling system components! |
| CAUTION | The battery must only be disconnected and connected with the ignition switched off. Otherwise, the engine control module (ECM) can be damaged. The use of nails, paper clips, or another unauthorized materials to back-probe electrical harness connectors is strictly prohibited and may cause damage to the electrical harness connectors, terminal ends or to a component. Use only the manufacturers test lead kit or an equivalent aftermarket test lead kit for back-probing all electrical harness connectors. Do not use sealants containing silicone. Particles of silicone drawn into the engine, will not be burnt in the engine and will damage the oxygen sensors. Secure all hose connections with the correct hose clips (the same as original equipment). If engine is to be cranked without starting, for example as part of a compression test, remove the fuses for the voltage supply of Ignition Coils and the fuel injector. An electrostatic charge can lead to functional problems of electrical components of the engine, transmission and selector lever mechanism. Touch a grounded object, e.g. a water pipe or a hoist, before working on electrical components. Do not make direct contact with electrical harness connector terminals. Use only gold-plated terminals when servicing any component with gold-plated electrical harness connector terminals. |
CLEAN WORKING CONDITIONS
Even minor contaminations can lead to malfunctions in the fuel injection system. When working on the fuel supply/injection system, pay careful attention to the following rules of cleanliness
- Thoroughly clean all connections and the surrounding area before disconnecting.
- Place removed parts on a clean surface and cover. Use lint-free cloths.
- Carefully cover over opened components or seal, if repairs are not performed immediately.
- When the system is open, do not work with compressed air. Do not move vehicle unless absolutely necessary.
- Install clean components: Remove replacement parts immediately prior to installation. Do not use parts that have been stored unpacked (e.g. in tool boxes etc.).
- Separated electrical connectors: Protect from dirt and moisture. Make sure connections are dry when reconnecting.
ON BOARD DIAGNOSTIC SYSTEMS
California OBD-II applies to all gasoline engine vehicles up to 14, 000 lbs. Gross Vehicle Weight Rating (GVWR) starting in the 1996 MY and all diesel engine vehicles up to 14, 000 lbs. GVWR starting in the 1997 MY.
Several states in the northeastern United States have chosen to adopt the California emission regulations starting in the 1998 MY and are known as "Green States".
Green States receive California-certified vehicles for passenger cars and light trucks up to 6, 000 lbs. GVWR. Starting in the 2004 MY, Federal vehicle over 8, 500 lbs. will start phasing in OBD-II.
Starting in 2004 MY, gasoline-fueled medium duty passenger vehicles are required to have OBD-II. Federal OBD-II applies to all gasoline engine vehicles up to 8, 500 lbs. GVWR starting in the 1996 MY and all diesel engine vehicles up to 8, 500 lbs. GVWR starting in the 1997 MY.
OBD-II system implementation and operation is described in the remainder of this document.
MALFUNCTION INDICATOR LAMP ILLUMINATION
If the engine control module (ECM) recognizes a malfunction that leads to increased emission values, it indicates them by illuminating the malfunction indicator lamp (MIL) which is located in the instrument cluster.
The ECM switches on the MIL after the ignition is switched on. Shortly after the engine is started, the MIL goes out if the ECM does not detect a malfunction that increases the emission values.
If the ECM recognizes a malfunction that leads to increased emissions during the operation of the engine, the ECM switches on the MIL and an entry is stored in the DTC memory of the ECM.
CONTROLLER AREA NETWORK DATA LINK
The engine control module (ECM) communicates with data bus capable control modules via a CAN Data Link.
The databus capable control modules are connected via data bus wires, which are twisted together (CAN high and CAN low), and exchange information with the ECM. Missing or implausible information on the databus is recognized and stored as a malfunction based on specific DTC criteria.
The malfunction indicator lamp (MIL) is illuminated as a result of a CAN message sent by the ECM. The MIL can be turned on, turned off, or blink, depending on the message received.
ELECTRONIC POWER CONTROL WARNING LAMP
The engine control module (ECM) monitors electronic power control (EPC) components when the ignition is switched on.
If a malfunction is recognized in the EPC system, the ECM switches on the EPC warning lamp, which is located in the instrument cluster, and an entry is stored in the DTC memory of the ECM.
DESCRIPTION AND OPERATION
Note. All manufacturers special tools as well as common tools may contain a manufacturer specific part number. These tools may be substituted with an equivalent aftermarket tool or are available for purchase through the manufacturer. Manufacturers special tools as well as common tools that contain a manufacturer specific part number may be referenced in the test procedure illustrations showing the tool use or installation. If the manufacturer specific tool is not being used, an equivalent aftermarket tool may be installed in the same manner as the manufacturers special tool.
FUEL SUPPLY SYSTEM
For all fuel supply system component locations, removal/installation procedures and torque specifications, refer to the service Information.
EVAPORATIVE EMISSION SYSTEM
The evaporative emission system has been designed to minimize the release of hydrocarbons from the fuel system into the atmosphere. The evaporative system components all work together with the ECM to prevent fuel vapor from escaping and route it to the intake manifold to be burned during normal combustion.
The leak detection system checks the integrity of the evaporative emission system by pressurizing system.
- When leak detection is activated, a pump pressurizes the evaporative system.
- During the leak diagnosis, the system is monitored for a specific time period. If the pressure does not drop a specific amount during the time period, the system is considered to be sealed.
- If the pressure drops greater than a specified amount during a specific time period, the system is pressurized once more. The engine control module measures the time until the pressure drops again. The control module uses the measured value to determine the size of the leak.
Leak diagnosis is activated automatically shortly following every engine start. If a malfunction is determined, an entry is made to the DTC memory. The Malfunction Indicator Lamp in the instrument cluster is illuminated if the malfunction is recognized for two subsequent starts.
For all evaporative system component locations, hose routing, removal/installation procedures and torque specifications, refer to the service Information.
ELECTRONIC ENGINE POWER CONTROL
For EPC, the throttle valve is not operated by a cable from the accelerator pedal. There is no mechanical connection between the accelerator pedal and the throttle valve.
The position of the accelerator pedal is communicated to engine control module (ECM) by the throttle position sensor / accelerator pedal position sensor 2 (variable resistances; stored in one housing) that are connected with the accelerator pedal.
The accelerator pedal position (driver's intention) is a main input unit for the ECM.
Operation of the throttle valve occurs via an electric motor, the throttle drive for in the throttle valve control module. This is true across the entire engine speed and engine load spectrum.
The throttle valve is operated by the EPC according to specifications of engine control module (ECM).
With engine off and ignition switched on, the ECM controls the throttle drive according to specifications of throttle position sensor / accelerator pedal position sensor 2. This means, if the accelerator pedal is pressed half way, the throttle drive opens the throttle valve to the same degree; i.e. throttle valve is then opened approximately half way.
With engine running under load, ECM can open or close the throttle valve independently of the throttle position sensor / accelerator pedal position sensor 2.
This means, for example, that the throttle valve could be fully opened even though the accelerator pedal has only been pressed half way. This has the advantage of preventing torque losses at the throttle valve.
In addition, it results in a significant reduction in emissions and fuel consumption under certain load conditions.
It would be incorrect to think that EPC consists of only one or two components. EPC is much more of a system containing all components that contribute to recognizing, controlling and monitoring the position of the throttle valve.
FUEL INJECTION SYSTEM
For all fuel injection system component locations, removal/installation procedures and torque specifications, refer to the service Information.
ENGINE CONTROL MODULE
The ECM regulates fuel injection, throttle valve control module, oxygen sensor regulation, ignition, knock control, evaporative emission purge valve, engine speed limitation through the fuel injectors or the power supply relay, as well as OBD functions. For locations, removal/installation procedures, refer to the service Information.
EXHAUST SYSTEM COMPONENTS
For all exhaust system, emission control component locations, removal/installation procedures and torque specifications, refer to the service Information.
SECONDARY AIR INJECTION SYSTEM
The secondary air injection system improves the secondary oxidation within the catalytic converter which are due to the rich mixture during the cold start phase where the exhaust emissions contain an increased level of unburned hydrocarbons, thereby reducing harmful emissions. The heat released by secondary oxidation shortens the startup time of the catalytic converter considerably, as well as significantly improves emissions quality during the cold-running phase.
- During a cold start, the secondary air injection system injects air behind the exhaust valves. This produces an oxygen rich exhaust gas, causes the after burning and reduces the heating-up phase of the catalytic converter.
- In addition, the secondary air injection system is switched on (after a delay) during idle after every subsequent engine start (up to a maximum coolant temperature) and is checked through on board diagnostic functions.
For all secondary air injection system component locations, removal/installation procedures and torque specifications, refer to the service Information.
IGNITION SYSTEM
For all ignition and glow plug system component locations, removal/installation procedures and torque specifications, refer to the service Information.
AUTOMATIC TRANSMISSION
The transmission control module receives information from transmission related components and uses this information to control shifting and operation of the transmission.
For all automatic transmission component locations, removal/installation procedures and torque specifications, refer to the service Information.
PRELIMINARY CHECK
Prior to component diagnosis, a preliminary check must be performed.
Connect the scan tool.
Switch the ignition on.
Using the scan tool, check for any stored or related DTCs.
If other DTCs are stored
Repair these DTCs first before performing the following procedure.
If no other DTCs are stored
Using the scan tool, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
Perform a road test to attempt to duplicate the customers complaint.
If the DTC returns
Perform the diagnostic procedure.
If the DTC does not return
The fault is intermittent or a sporadic condition may exist.
Check the suspected component, electrical harness and electrical harness connectors for damage, corrosion, loose or broken terminals.
If necessary, repair the faulty wiring connection.
Perform a road test to verify the repair.
If the DTC returns
Perform the diagnostic procedure.
If the DTC does not return
The fault may have been the result of a loose electrical connection.
Generate readiness code. Refer to READINESS CODE .
READINESS CODE
Readiness code description
Diagnostics are performed at regular intervals during normal vehicle operation. After repairing an emissions related system, a readiness code is generated by road testing the vehicle.
If a malfunction is recognized during the drive cycle, it will be stored in the DTC memory.
The OBD drive cycle operation will be monitored with a hand held diagnostic tool. Consult the manufacturer's instruction Information for correct tool operation.
The readiness code is erased every time the DTC memory is erased or any time the battery is disconnected. If the DTC memory has been erased or the battery is disconnected, a new readiness code must be generated.
Only erase the DTC memory if a DTC has been stored.
General recommendations
Most monitors will complete easier and quicker using a "steady-foot" and "smooth" acceleration during the drive cycle operation, cruise, and acceleration modes.
Operating conditions
For the EVAP monitor test, the coolant temperature and the ambient air temperature must be between 10° C and 35° C with a difference between them no greater than 4° C. The ambient air temperature must not change more than 4° C during the drive cycle procedure (e.g. when driving out of a heated workshop in the winter).
Test requirements
- Erase the DTC memory.
- Coolant temperature must be between 80° C and 110° C.
- The intake air temperature must be between 10° C and 35° C.
- Battery voltage must be a minimum of 12.5 volts.
- Fuel tank level 1/4 to 3/4 full.
Drive Cycle Procedure
Connect the scan tool.
Switch the ignition on and start the vehicle.
Idle the vehicle for 2-3 minutes. This executes the O2 heater, misfire, secondary air injection, fuel trim, and purge system monitors.
Drive the vehicle at 45-55 mph for a continuous 7-minute period - avoid stopping. This executes the evaporative, O2 sensor, fuel trim, and misfire monitors.
Accelerate the vehicle to an engine speed of 5000 RPM; lift off the throttle until the engine speed is around 1200 rpm. This executes the fuel cut off.
Accelerate the vehicle smoothly to 60-65 mph, cruise constantly for 5 min, this executes the catalyst; O2 sensor, misfire, fuel trim, and purge system monitors.
Decelerate and idle the vehicle again for 3 minutes. This executes the misfire, secondary sir injection, fuel trim, and purge system monitors.
Check the status of the readiness code.
Note. Depending on the scan tool used. The readiness code status may be displayed as complete, passed or OK.
If any engine monitor fails the drive cycle test. Repeat the drive cycle test until all engine monitors have successfully run through and passed.
Note. When repeating the drive cycle operation for a failed evaporative or thermostat monitor, allow the engine to cool until the coolant temperature and the ambient air temperature are be between 10° C and 35° C with a difference no greater than 4° C and repeat the drive cycle operation.
If the drive cycle operation fails again.
Check the DTC memory for stored DTCs.
Repair the vehicle if necessary.
Repeat the drive cycle operation until all engine monitors have successfully run through and passed.
Remove the scan tool and switch the ignition off.

DIAGNOSTIC MODE 07 - READ FAULTS DETECTED DURING THE CURRENT OR LAST DRIVING CYCLE
Mode 07 makes it possible to check emissions-related faults which appeared during the current or last driving cycle (pending DTCs).
A pending DTC is saved the first time a fault is detected (output via Mode 07).
If the fault is detected again by the end of the following driving cycle, a confirmed DTC is entered (output via Mode 03) and the MIL is activated.
If this malfunction is not detected again by the end of the following driving cycle, the corresponding pending code will be deleted at the end of the driving cycle.
Note. Depending on scan tool and protocol used, some of the information provided may be referred to by a different name.

A leak may be present. Refer to EVAPORATIVE SYSTEM, CHECKING FOR LEAKS .
DIAGNOSTIC MODE 09 - READ VEHICLE INFORMATION
Diagnostic Mode 09 makes it possible to access vehicle-specific information from the ECM and the TCM (where applicable).
Note. Depending on scan tool and protocol used, Diagnostic Mode 09 and the information provided may be referred to by a different name.
Test requirement
- No DTCs stored in the DTC memory.
Procedure
Connect the scan tool.
Switch the ignition on.
Select Mode 09: Vehicle information.
Select the desired Test-ID.
The information requested will be displayed on the scan tool screen.
The following table is a numerical list of all Test-IDs that may be selected.
| Test-ID | Diagnostic text |
|---|---|
| 02 | Vehicle identification number e.g. |
| A different 17 digit number will be displayed for each vehicle | |
| 04 | Calibration identification e.g. |
| Engine Control Module (ECM) | |
| Transmission Control Module (TCM) | |
| 06 | CVN (check sum) e.g. |
| EC5AE460 the check sum is different for every control module version | |
| 000D105 |
Switch the ignition off.
DIAGNOSTIC MODE 0A - CHECK PERMANENT DTC MEMORY
Mode 0A - Check Permanent DTC Memory (Request emissions-related diagnostic trouble codes with permanent status after code clear)
Permanent Fault Codes From MY 2010 with Phase-In conforming to CCR 1968.2 (d) (2.2.5): 50% from MY 2010 / 75% from MY 2011 / 100% from MY 2012 The vehicle only participates in Phase-In if all of the OBD-relevant control modules in the vehicle meet these requirements.
Mode 0A may only be supported exclusively by OBD control modules in US vehicles. Mode 0A may not be supported in EOBD vehicles, meaning the control module may not send a response here.
Mode 0A enables the request of all OBD-relevant faults with the status "Permanent Fault Code": -Permanent Fault Codes are Confirmed Fault Codes that are currently activating the MIL. That means faults that are still displayed in Mode 03 but no longer activate the MIL (History Fault Codes) are not Permanent Fault Codes. -Permanent Fault Codes are updated in Mode 0A at the same time as NVRAM storage immediately after switching the ignition off. A newly detected Permanent Fault Code is only visible after switching the ignition off/on in Mode 0A. -Permanent Fault Codes may only be erased in the control module after they are corrected as long as the last diagnostic result was a PASS and the MIL is no longer activated by this fault. The Permanent Fault Codes should be erased from Mode 0A at the same time the MIL switches off when the ignition is switched off/on. -Permanent Fault Codes may not be erased by clearing the DTC memory or disconnecting the power supply. Storage in NVRAM is required. -Permanent Fault Codes may only be erased after clearing the DTC memory under the following conditions: -As long as no FAIL diagnostic result was detected for a Permanent Fault Code -and at least one PASS diagnostic result was detected -and the Minimum Trip Conditions for a General Denominator (without considering high/ambient temperature) were met in this phase in any DCY after erasing the DTC memory. -The engine control module relays the message "Minimum Trip conditions met" to all other OBD control modules via CAN: CAN message OBD_01, Byte 8, Bit 4: OBD_Minimum_Trip -Permanent Fault Codes may NOT be erased if the diagnostic result is FAIL after clearing the DTC memory. A Pending Fault Code should be stored and the DTC memory line should be overwritten with new Freeze Frame data. (Exception: If the Pending Fault Code is corrected without a Confirmed Fault Code being detected, the Permanent Fault Code may also be erased under the conditions described below.) -Permanent Fault Codes should be erased in engine control modules after Update Programming. At this time, all readiness bits (Mode 01 PID $01) must be reset to "not complete" [ (g) (4.4.6) (D) ]. Permanent Fault Codes should not be erased in OBD control modules with Comprehensive Components (CCM) as a single readiness bit if the identical program/data status is being programmed. If a different program/data status is being programmed, Permanent Fault Codes should be erased after Update Programming. -The procedure in Mode 01 through Mode 09 and in the service tester is NOT affected by implementation of the Permanent Fault Codes.
