3.CHECK LOAD SIGNAL CIRCUIT OVERALL FUNCTION-II
Without CONSULT-II
Check voltage between ECM terminal 84 and ground under the fol-
lowing conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 5.
4.CHECK REAR WINDOW DEFOGGER SYSTEM
Refer to EL-173.
>>INSPECTION END
5.CHECK HEADLAMP FUNCTION
1. Turn lighting switch “ON” at 2nd position.
2. Check that headlamps are illuminated.
OK or NG
OK >> GO TO 6.
NG >> Refer to EL-42 or EL-46 .
6.CHECK HEADLAMP INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
WITHOUT DAYTIME LIGHT SYSTEM
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector.
3. Disconnect lighting switch harness connector.
4. Check harness continuity between ECM terminal 84 and lighting switch terminal 10.
Refer to Wiring Diagram.
5. Also check harness for short to ground and short to power.
WITH DAYTIME LIGHT SYSTEM
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector.
3. Disconnect daytime light relay.
4. Check harness continuity between ECM terminal 84 and daytime light relay terminal 3.
Refer to Wiring Diagram.
5. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 8.
NG >> GO TO 7.
Condition Voltage
Lighting switch “ON” at 2nd position Battery voltage
Lighting switch “OFF” Approximately 0V

PRECAUTIONS
●Do not depress accelerator pedal when starting.
●Immediately after starting, do not rev up engine unneces-
sarily.
●Do not rev up engine just prior to shutdown.
●When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standing-
wave radio can be kept smaller.
–Be sure to ground the radio to vehicle body.
Wiring Diagrams and Trouble DiagnosisEBS00KE5
When you read wiring diagrams, refer to the following:
●GI-12
●EL-11 for power distribution circuit
When you perform trouble diagnosis, refer to the following:
●GI-32
