STEP 6. Check the wiring harness between fog light (LH)
connector A-41or fog light (RH) connector A-51 (terminal
2) and fog light relay connector A-14X (terminal 3).
NOTE: Also check intermediate connector A-46 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector A-46 is damaged, repair or
replace the connector as described in GROUP 00E, Harness

P.00E-2
.
• Check the power supply line for open circuit.
Q: Is the wiring harness between fog light (LH) connector
A-41 or fog light (RH) connector A-51 (terminal 2) and
fog light relay connector A-14X (terminal 3) in good
condition?
YES : Go to Step 7.
NO : Repair the wiring harness.
STEP 7. Retest the system.
Q: Does the right or left fog light illuminate in good
condition?
YES : The trouble can be an intermittent malfunction (Refer
to GROUP 00, How to use
Troubleshooting/inspection Service Points
− How to
Cope with Intermittent Malfunction
P.00-15
).
NO : Go to Step 1.
Inspection Procedure 3: Fog light indicator does not illuminate/go out normally.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
