km/h (6 MPH).
Diagnostic Procedure 11
(Pedal vibration and noise)
INSPECTION START
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Apply brake.
2. Start engine.
3. Does the symptom appear only when
engine is started?
No
cYes
Carry out self-diagnosis.
Refer to BR-53, 57.
CHECK IF SYMPTOM APPEARS.

are operated?
Yes
cNo
Go toin Diagnostic
Procedure 8, BR-73.
CHECK WHEEL SENSOR.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check wheel sensor shield ground. For
location of shield ground, refer to wiring
diagram and ``HARNESS LAYOUT'' in EL
section.
OK
cNG
Repair wheel sensor.
CHECK HARNESS CONNECTOR.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check ABS actuator and electric unit pin
terminals for damage or the connection of

TROUBLE DIAGNOSES FOR SYMPTOMS
BR-74

Idle Speed/Ignition Timing/Idle Mixture Ratio
Adjustment
PREPARATION
lMake sure that the following parts are in
good order.
(1) Battery
(2) Ignition system
(3) Engine oil and coolant levels
(4) Fuses
(5) ECM harness connector
(6) Vacuum hoses
(7) Air intake system
(Oil filler cap, oil level gauge, etc.)
(8) Fuel pressure(9) Engine compression
(10) Throttle valvelOn air conditioner equipped models,
checks should be carried out while the air
conditioner is ``OFF''.
lWhen measuring ``CO'' percentage, insert
probe more than 40 cm (15.7 in) into tail
pipe.
lTurn off headlamps, heater blower, rear
window defogger.
lKeep front wheels pointed straight ahead.

BASIC SERVICE PROCEDUREKA
EC-25

Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
lHeadlamp switch is OFF,
lAir conditioner switch is OFF,
lRear window defogger switch is OFF,
lSteering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any recent
repairs that may indicate a related
problem, or the current need for sched-
uled maintenance.
2. Open engine hood and check the fol-
lowing:
lHarness connectors for improper con-
nections
lVacuum hoses for splits, kinks, or
improper connections
lWiring for improper connections,
pinches, or cuts
CONNECT CONSULT TO THE
VEHICLE.
Connect ``CONSULT'' to the data link
connector for CONSULT and select
``ENGINE'' from the menu. Refer to
EC-45.
CHECK IGNITION TIMING.
1. Warm up engine sufficiently.
2. Select ``IGN TIMING ADJ'' in
``WORK SUPPORT'' mode.
3. Touch ``START''.
4. Check ignition timing at idle
using timing light.
Ignition timing:
10É 2É BTDC
----------------------------------------------------------------------------------------------------------------------------------OR----------------------------------------------------------------------------------------------------------------------------------
1. Warm up engine sufficiently.
2. Stop engine and disconnect
throttle position sensor sub-
harness connector.
3. Start engine.
4. Check ignition timing at idle
using timing light.
Ignition timing:
10É 2É BTDC
OK
cNG
Adjust ignition timing by
turning camshaft position
sensor.
