DIAGNOSIS PROCEDURE
STEP 1. Check that the rear fog lamp indicator
operate.
Check that the rear fog lamp indicator illuminates.
Q: Does the rear fog lamp indicator illuminate?
YES :
Go to Step 12.
NO :
Go to Step 2.
STEP 2. Check that the tail/stop lamps and
headlamps operate.
Check that the tail/stop lamps and headlamps illumi-
nate normally.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the tail/stop lamp(s) and
headlamp(s). Refer to trouble symptom
chart
STEP 3. M.U.T.-III diagnosis code.
When the ignition switch is turned to the "LOCK"
(OFF) position, check that the ETACS-ECU does not
set the diagnosis code.
Q: Is the diagnosis code set?
YES :
Refer to diagnosis code chart
.
NO :
Go to Step 4.
STEP 4. M.U.T.-III data list
Check the input signals below, which are related to
the rear fog lamp.
• Turn the ignition switch to the "LOCK" (OFF)
position.
• Turn the tail lamp switch to the ON position.
• Turn the rear fog lamp switch to the ON position.
OK: Normal conditions are displayed for all
the items
Q: Are the check result normal?
YES <All the signals are received normally.> :
Go
to Step 5.
NO <The ignition switch (IG1) signal is not
received.> :
Refer to inspection procedure C-3

received
."
NO <The rear fog lamp switch signal is not
received.> :
Refer to inspection procedure C-1
"The column switch (lighting and wiper
switch) signal is not received

STEP 7. Voltage measurement at the C-215 rear
fog lamp relay connector.
(1) Remove the rear fog lamp relay, and measure at
the junction block side.
(2) Check the voltage between the rear fog lamp
relay connector and body earth.
• Voltage between C-215 rear fog lamp relay
connector terminal No.1 and body earth
• Voltage between C-215 rear fog lamp relay
connector terminal No.4 and body earth
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 9.
NO :
Go to Step 8.
STEP 8. Check the wiring harness between C-215
rear fog lamp relay connector terminals Nos.1, 4
and the fusible link (20).
NOTE: Prior to the wiring harness inspection, check
junction block connector C-213, and repair if neces-
sary.
• Check the power supply line for open circuit and
short circuit.
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Repair the wiring harness.
