Scheme 31

1. Do not operate the engine for an extended period of time without proper exhaust ventilation. Keep the work area well ventilated and free of any inflammable materials. Special care should be taken when handling any inflammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while working on the vehicle.
2. Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jacking up the vehicle, support the vehicle weight with safety stands at the points designated for proper lifting before working on the vehicle. These operations should be done on a level surface.
3. When removing a heavy component such as the engine or transaxle/transmission, be careful not to lose your balance and drop them. Also, do not allow them to strike adjacent parts, especially the brake tubes and master cylinder.
4. Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal.
5. If the battery terminals are disconnected, recorded memory of radio and each control unit is erased.
6. To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot.
7. Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
8. Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically. Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
9. Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
10. Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
11. Replace inner and outer races of tapered roller bearings and needle bearings as a set.
12. Arrange the disassembled parts in accordance with their assembled locations and sequence.
13. Do not touch the terminals of electrical components which use microcomputers (such as ECM) Static electricity may damage internal electronic components.
14. After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
15. Use only the fluids and lubricants specified in this information.
16. Use approved bonding agent, sealants or their equivalents when required.
17. Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
18. When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
19. Before servicing the vehicle: Protect fenders, upholstery and carpeting with appropriate covers. Take caution that keys, buckles or buttons do not scratch paint.

Three Way Catalyst

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions.

1. Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
2. When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the catalyst. Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three way catalyst.

Fuel (Regular Unleaded Gasoline Recommended) HR16DE

Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91). E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) may only be used in vehicles specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models).

Multiport Fuel Injection System or Engine Control System

1. Before connecting or disconnecting any harness connector for the multiport fuel injection system or ECM: Turn ignition switch to "OFF" position. Disconnect negative battery terminal. Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure.
3. Be careful not to jar components such as ECM and mass air flow sensor.

1. If old rubber hose is re-used, install hose clamp in its original position (at the indentation where the old clamp was). If there is a trace of tube bulging left on the old rubber hose, align rubber hose at that position.
2. Discard old clamps; replace with new ones.
3. After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.

Engine Oils

Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact with used oil.

If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

HEALTH PROTECTION PRECAUTIONS

1. Avoid prolonged and repeated contact with oils, particularly used engine oils.
2. Wear protective clothing, including impervious gloves where practicable.
3. Do not put oily rags in pockets.
4. Avoid contaminating clothes, particularly underpants, with oil.
5. Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly.
6. First aid treatment should be obtained immediately for open cuts and wounds.
7. Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
8. Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed.
9. Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
10. If skin disorders develop, obtain medical advice without delay.
11. Where practical, degrease components prior to handling.
12. Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility should be provided.

ENVIRONMENTAL PROTECTION PRECAUTIONS

Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal facilities.

It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources. The regulations concerning pollution vary between regions.

HOW TO PROBE CONNECTORS

1. Connector damage and an intermittent connection can result from improperly probing of the connector during circuit checks.
2. The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the connector, follow the procedures below using a "T" pin. For the best contact grasp the "T" pin using an alligator clip.

Probing from Terminal Side

FEMALE TERMINAL

Scheme 53

Scheme 54

1. There is a small notch above each female terminal. Probe each terminal with the "T" pin through the notch. Do not insert any object other than the same type male terminal into female terminal.
2. Some connectors do not have a notch above each terminal. To probe each terminal, remove the connector retainer to make contact space for probing.

MALE TERMINAL

Scheme 55

1. Carefully probe the contact surface of each terminal using a "T" pin. CAUTION: Dot not bend terminal.

How to Check Enlarged Contact Spring of Terminal

1. An enlarged contact spring of a terminal may create intermittent signals in the circuit.
2. If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged contact spring of female terminal.

Scheme 56

Scheme 57

Scheme 58

Scheme 59

1. Assemble a male terminal and approx. 10 cm (3.9 in) of wire. NOTE: Use a male terminal which matches the female terminal.
2. Disconnect the suspected faulty connector and hold it terminal side up.
3. While holding the wire of the male terminal, try to insert the male terminal into the female terminal. CAUTION: Do not force the male terminal into the female terminal with your hands.
4. While moving the connector, check whether the male terminal can be easily inserted or not. If the male terminal can be easily inserted into the female terminal, replace the female terminal.

Hint

Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system.

Sensor & Relay

Gently apply a slight vibration to sensors and relays in the system you are inspecting.

This test may indicate a loose or poorly mounted sensor or relay.

Scheme 60

Engine Compartment

There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things to check for are

1. Connectors not fully seated.
2. Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
3. Wires laying across brackets or moving components.
4. Loose, dirty or corroded ground wires.
5. Wires routed too close to hot components.

To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground Inspection described later.) First check that the system is properly grounded. Then check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the wiring for continuity.

Behind the Instrument Panel

An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harness which is routed along a bracket or near a screw.

Under Seating Areas

An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides) during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or pinching.

Scheme 61

1. The customer's concern may occur during hot weather or after car has sat for a short time. In such cases you will want to check for a heat sensitive condition.
2. To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent. CAUTION: Do not heat components above 60°C (140°F).
3. If incident occurs while heating the unit, either replace or properly

FREEZING

1. The customer may indicate the incident goes away after the car warms up (winter time). The cause could be related to water freezing somewhere in the wiring/electrical system.
2. There are two methods to check for this. The first is to arrange for the owner to leave his car overnight. Make sure it will get cold enough to demonstrate his complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be affected.
3. The second method is to put the suspect component into a freezer long enough for any water to freeze. Reinstall the part into the car and check for the reoccurrence of the incident. If it occurs, repair or replace the component.

Scheme 62

WATER INTRUSION

The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car wash.

Scheme 63

ELECTRICAL LOAD

The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window defogger, radio, fog lamps) turned on.

Scheme 64

COLD OR HOT START UP

On some occasions an electrical incident may occur only when the car is started cold, or it may occur when the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to make a proper diagnosis.

Continuity Check Method

The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Make sure to always start with the DMM at the highest resistance level.

To help in understanding the diagnosis of open circuits, please refer to the previous schematic.

1. Disconnect the battery negative cable.
2. Start at one end of the circuit and work your way to the other end. (At the fuse block in this example)
3. Connect one probe of the DMM to the fuse block terminal on the load side.
4. Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point A)
5. Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point B)
6. Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point C) Any circuit can be diagnosed using the approach in the previous example.

Voltage Check Method

To help in understanding the diagnosis of open circuits please refer to the previous schematic.

In any powered circuit, an open can be found by methodically checking the system for the presence of voltage.

This is done by switching the DMM to the voltage function.

1. Connect one probe of the DMM to a known good ground.
2. Begin probing at one end of the circuit and work your way to the other end.
3. With SW1 open, probe at SW1 to check for voltage. voltage; open is further down the circuit than SW1. no voltage; open is between fuse block and SW1 (point A).
4. Close SW1 and probe at relay. voltage; open is further down the circuit than the relay. no voltage; open is between SW1 and relay (point B).
5. Close the relay and probe at the solenoid. voltage; open is further down the circuit than the solenoid. no voltage; open is between relay and solenoid (point C). Any powered circuit can be diagnosed using the approach in the previous example.

Resistance Check Method

1. Disconnect the battery negative cable and remove the blown fuse.
2. Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.
3. Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known good ground.
4. With SW1 open, check for continuity. continuity; short is between fuse terminal and SW1 (point A). no continuity; short is further down the circuit than SW1.
5. Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. continuity; short is between SW1 and the relay (point B). no continuity; short is further down the circuit than the relay.
6. Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity. continuity; short is between relay and solenoid (point C). no continuity; check solenoid, retrace steps.

1. Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.
2. Turn the ignition key to the ON or START position. Verify battery voltage at the battery + side of the fuse terminal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground).
3. With SW1 open and the DMM leads across both fuse terminals, check for voltage. voltage; short is between fuse block and SW1 (point A). no voltage; short is further down the circuit than SW1.
4. With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check for voltage. voltage; short is between SW1 and the relay (point B). no voltage; short is further down the circuit than the relay.
5. With SW1 closed, relay contacts jumped with fused jumper wire check for voltage. voltage; short is down the circuit of the relay or between the relay and the disconnected solenoid (point C). no voltage; retrace steps and check power to fuse block.

VOLTAGE DROP TESTS

1. Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistance when the circuit is in operation.
2. Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire is not able to carry the current. The single strand will have a high resistance to the current. This will be picked up as a slight voltage drop.
3. Unwanted resistance can be caused by many situations as follows: Undersized wiring (single strand example) Corrosion on switch contacts Loose wire connections or splices.
4. If repairs are needed always use wire that is of the same or larger gauge.

Measuring Voltage Drop - Accumulated Method

1. Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the DMM should be closer to power and the negative lead closer to ground.
2. Operate the circuit.
3. The DMM will indicate how many volts are being used to "push" current through that part of the circuit.

Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.

Scheme 65

Measuring Voltage Drop - Step-by-Step

1. The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in "Computer Controlled Systems").
2. Circuits in the "Computer Controlled System" operate on very low amperage.
3. The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by poor connection, improper installation, improper wire gauge or corrosion.
4. The step by step voltage drop test can identify a component or wire with too much resistance.
