ITEM 6-10
All Latches, Hinges and Locks Inspection
Doors
Check that each door of front, rear and back doors opens and
closes smoothly and locks securely when closed.
If any malfunction is found, lubricate hinge and latch or repair door
lock system.
Engine hood
Check that secondary latch operates properly (check that second-
ary latch keeps hood from opening all the way even when pulling
hood release handle inside vehicle.). Also check that hood opens
and closes smoothly and properly and hood locks securely when
closed.
If any malfunction is found, lubricate hinge and latch, or repair hood
lock system.

MAINTENANCE AND LUBRICATION 0B-21
[Parking brake]
Check that lever has proper travel.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
Steering

Check to ensure that steering wheel is free from in-
stability, or abnormally heavy feeling.

Check that the vehicle does not wander or pull to
one side.
Engine

Check that engine responds readily at all speeds.

Check that engine is free from abnormal noise and
abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting sys-
tem are free from abnormal noise and abnormal
vibration or any other abnormal condition.
Meters and Gauge
Check that speedometer, odometer, fuel meter, tem-
perature gauge, etc. are operating accurately.
Lights
Check that all lights operate properly.
Windshield Defroster
Periodically check that air comes out from defroster
outlet when operating heater or air conditioning.
Set fan switch lever to “HI” position and mode lever to
defroster position for this check. WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.

“IG COIL METER”Main relay
Ignition switch
In fuseMalfunction indicator lamp in combination meter
TABLE A-1 MALFUNCTION INDICATOR LAMP CIRCUIT CHECK – LAMP DOES
NOT COME “ON” AT IGNITION SWITCH ON (BUT ENGINE AT STOP)
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, ECM (PCM) causes the main relay to turn ON (close the contact point).
Then, ECM (PCM) being supplied with the main power, turns ON the malfunction indicator lamp (MIL). When the
engine starts to run and no malfunction is detected in the system, MIL goes OFF but if a malfunction was or is de-
tected, MIL remains ON even when the engine is running.
INSPECTION
STEPACTIONYESNO
1MIL Power Supply Check
1) Turn ignition switch ON.
Do other indicator / warning lights in
combination meter comes ON?Go to Step 2.“IG COIL METER” fuse blown,
main fuse blown, ignition
switch malfunction, “B/W”
circuit between “IG COIL
METER” fuse and
combination meter or poor
coupler connection at
combination meter.
2ECM (PCM) Power and Ground Circuit
Check
Does engine start?Go to Step 3.Go to TABLE A-3 ECM (PCM)
POWER AND GROUND
CIRCUIT CHECK.
If engine is not cranked, go to
DIAGNOSIS in SECTION 8A.
3MIL Circuit Check
1) Turn ignition switch OFF and disconnect
connectors from ECM (PCM).
2) Check for proper connection to ECM
(PCM) at terminal C02-17.
3) If OK, then using service wire, ground
terminal C02-17 in connector
disconnected.
Does MIL turn on at ignition switch ON?Substitute a known-
good ECM (PCM) and
recheck.Bulb burned out or “V/Y” wire
circuit open.
