GENERAL INFORMATIONM1543000100319
Rear Defogger operation
The defogger relay turns ON if the defogger switch
built-in the A/C-ECU is turned ON when the ignition
switch is in the "ON" position. When the defogger
relay turns ON, power is supplied to the defogger
and the defogger is activated. The defogger comes
with a timer function that causes the defogger switch
to automatically turn OFF in about 11 minutes after
the defogger switch is turned ON.
TROUBLESHOOTINGM1543000701013
The rear window defogger is controlled by the
A/C-ECU. For troubleshooting, refer to GROUP 55-
Troubleshooting P.55-5.

ON-VEHICLE SERVICE
PRINTED HEATER LINES CHECKM1543001800311
1. Run engine at 2,000 r/min. Check heater element
with battery at full.
2. Turn "ON" rear window defogger switch. Measure
heater element voltage with circuit tester at rear
window glass centre A. Condition is good if it
indicates about six volts.
3. If 12 volts is indicated at A, there is a break in the
negative terminals from A. Move test bar slowly to
negative terminal to detect where voltage
changes suddenly (0 volts).
4. If 0 volts is indicated at A, there is a break in the
positive terminals from A. Defect where the
voltage changes suddenly (12 volts) in the same
method described above.

STEP 4. Connector check: C-213 rear window
defogger relay connector
Q: Is the check result normal?
YES :
Go to Step 5.
NO : Repair the connector.
STEP 5. Check the rear window defogger relay
continuity.
Refer to P.54A-96.
Q: Is the rear window defogger relay continuity in
good condition?
YES :
Go to Step 6.
NO : Replace the rear window defogger relay.
STEP 6. Voltage measurement at C-213 rear
window defogger relay connector.
(1) Remove the relay, and measure at the junction
block side.
(2) Measure the voltage between terminal 5 and
body earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 9.
NO : Go to Step 7.
NO : Go to Step 8.

STEP 16. Check the wiring harness between F-06
rear window defogger connector terminal No.1
and earth.
•Check the rear window defogger earth line for
open circuit.Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00, How to
Cope with Intermittent Malfunction P.00-5).
NO : Repair the wiring harness.
STEP 17. Check the rear window defogger.
Refer to GROUP 54A, Rear window defogger
P.54A-96.
Q: Does the rear window defogger work normally?
YES :
Replace the manual air conditioner control
panel (A/C-ECU) or the heater control unit.
NO : Repair the rear window defogger.
INSPECTION PROCEDURE 8: Rear Window Defogger Timer Function does not Operate.
COMMENTS ON TROUBLE SYMPTOM
Turn ON the rear window defogger switch. If the rear
window defogger does not shut off after roughly 11
minutes then the rear window defogger timer is
malfunctioning.
TROUBLESHOOTING HINTS
•Malfunction of the manual air conditioner control
panel (A/C-ECU) or the heater control unit
DIAGNOSIS
Check the performance of the rear window
defogger timer operations.
(1) Turn the ignition switch to the "ON" position.
(2) Turn the rear window defogger switch to the "ON"
position (operate for approx. 11 minutes)
Q: Does the rear window defogger timer function
work normally?
YES :
Intermittent malfunction
NO : Replace the manual air conditioner control
panel (A/C-ECU) or the heater control unit.
