•Before beginning any electrical work, turn the igni-
tion switch to LOCK, disconnect the negative bat-
tery cable and then wait two minutes to allow the
backup supply of the air bag diagnostic monitor unit
to deplete its stored power.
• Disconnecting the battery cable deletes the memo-
ries of the clock, audio and DTCs, etc. Therefore, it
is necessary to verify those memories before dis-
connecting the cable.

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 in the circuit during operation.
•Check the circuit using a Digital Multimeter (DMM).
• When measuring resistance with a DMM, remember that contact by a single strand of wire will give a 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 indicated as a
slight voltage drop.
• Unwanted resistance can be caused by the following:
Undersized wiring (single strand example)
Corrosion on switch contacts
Loose wire connections or splices
Precautions For Handling Control Modules and Electrical Components
•Never reverse polarity of battery terminals.
• Only install components specified for the vehicle.
• Before replacing the control module, check the input and output and functions of the components.
• When disconnecting components:
Do not apply excessive force when disconnecting a connector.
If a connector is installed by tightening bolts, loosen mounting bolt, then remove it by hand.
• When connecting components:
Before installing a connector, make sure the terminal is not bent or damaged, and then correctly connect it.
When installing a connector by tightening bolts, tighten the mounting bolt until the painted area of the con-
nector becomes even with the surface.
• Do not apply excessive shock to the control module by dropping or hitting it.
• Be careful to prevent condensation in the control module due to rapid temperature changes and do not let
water or rain get on it. If water is found in the control unit, dry it fully and then install it in the vehicle.
• Be careful not to let oil get on the control module connector.
• Avoid cleaning the control module with volatile oil.
• When using a DMM, be careful not to let the test probes touch each other causing a short circuit. Prevent the
power transistor in the control module from being
shorted to damaging battery voltage.
• When checking input and output signals of the con-
trol module, use the specified test adapter (if
applicable).

DIAGNOSIS & TESTING

Downloaded from www.Manualslib.com manuals search engine Cylinder Compression Pressure Test
•The result of a cylinder compression pressure test can be utilized to diagnose several engine malfunctions.
• Ensure the battery is completely charged and the engine starter motor is in good operating condition. Otherwise
the indicated compression pressures may not be valid for diagnostic purposes.
Check engine oil level and add oil if necessary.
Disconnect the spark plug wires.
Remove all spark plugs from engine (as spark plugs are being removed, check electrodes for abnormal
firing indicators fouled, hot, oily, etc.).
Record cylinder number of each spark plug for future reference.
Disconnect fuel injector electrical connectors.
Be sure throttle blade is fully open during the compression check.
Insert compression pressure adaptor or the equivalent into each spark plug hole in cylinder head.
Crank engine until maximum pressure is reached on gauge. Record each cylinder pressure.
Compression should not be less than 1000 kPa and not vary more than 25 percent from cylinder to cylinder.
If one or more cylinders have abnormally low compression pressures, repeat the compression test.
If the same cylinder or cylinders repeat an abnormally low reading on the second compression test, it could indicate the existence of a problem with the cylinder in question.
NOTE :
The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine
should not be disassembled to determine the cause of low compression unless some malfunction is present.
Cylinder Head Gasket Test
• A cylinder head gasket leak can be located between adjacent cylinders, between a cylinder and the adjacent
water jacket or from an oil passage to the exterior of the engine.
• Possible indications of the cylinder head gasket leaking between adjacent cylinders are:
Loss of engine power
Engine misfiring
Poor fuel economy
• Possible indications of the cylinder head gasket leaking between a cylinder and an adjacent water jacket are:
Engine overheating
Loss of coolant
Excessive steam (white smoke) emitting from exhaust
Coolant foaming
