SYMPTOM PROCEDURES

The rear window defogger does not work.

CAUTION

• Before replacing the ECU, ensure that the 

power supply circuit, the earth circuit and the 
communication circuit are normal.

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
Immobilizer System 

 How to Register Key ID 

P.54A-33

.)

COMMENTS ON TROUBLE SYMPTOM

The rear window defogger relay may be defective 
when the rear window defogger cannot be activated 
although the rear window defogger switch is turned 
on (the 20-minute timer initiates) or the ambient tem-
perature is 3 

°C or less (the rear window defogger 

has never been activated since the ignition switch is 
turned ON) with "Auto Rear Defogger (Engine Start)" 
enabled by using the customisation function of the 
ETACS-ECU.

NOTE: When the engine is not running, the rear win-
dow defogger does not work.

PROBABLE CAUSES

• Wiring harness or connector failure

• Malfunction of A/C-ECU

• Malfunction of ETACS-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics
Use M.U.T.-III to diagnose the CAN bus lines.

Q: Is the check result normal?

YES : 

Go to Step 2

NO : 

Repair the CAN bus line (Refer to GROUP 
54C 

− Troubleshooting ).

STEP 2. M.U.T.-III diagnosis code
Check that the air conditioner has not set a diagnosis 
code.

Q: Is the diagnosis code set?

YES : 

Carry out the diagnosis code procedures. 

(Refer to GROUP 55-trouble shooting .)

NO : 

Go to Step 3

STEP 3. M.U.T.-III other system's diagnosis code
Check that the ETACS-ECU has not set a diagnosis 
code.

Q: Is the diagnosis code set?

YES : 

Carry out the diagnosis code procedures. 

Refer to 

P.54A-281

.

NO : 

Go to Step 4

STEP 4. M.U.T.-III data list
Check the rear window defogger switch signal by the 
data list of the A/C-ECU.

• Start the engine.

Item No.

Item name

Normal 
condition

Item 60

Rear defogger 
switch

OFF 

→ ON

Turn the rear window defogger switch from off to 
on.

Q: Is the check result normal?

YES : 

Go to Step 5

NO : 

Refer to GROUP 55 

− Inspection Procedure 

13 "A/C-ECU power supply system" 

STEP 5. Voltage measurement at rear window 
defogger connector (power supply terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Ignition switch: ON
(3) Rear window defogger switch must be turned on, 

or the operational conditions for the 
customisation function "Auto Rear Defogger 
(Engine Start)" must be satisfied (measure within 
20 minutes after the switch is turned on).

(4) Check the voltage between the rear window 

defogger connector (power supply terminal) and 
body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 6

NO : 

Go to Step 8

STEP 6. Resistance measurement at rear window 
defogger connector (earth terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.
