INSPECTION PROCEDURE E-2: Keyless Entry hazard lamp answerback function or the Room Lamp 
Answerback Function does not Work Normally.

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the hazard warning lamp and the room lamp work 
normally, the ETACS-ECU may be defective.
Alternatively, it is possible that the keyless entry 
hazard lamp answerback function was disabled by 
the adjustment function.

POSSIBLE CAUSES

•

Defective turn-signal lamp

•

Malfunction of the room lamp

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the adjustment function.

Check that the keyless entry hazard lamp 
answerback function has been enabled by using the 
adjustment function.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Enable the keyless entry hazard lamp 
answerback function by using the 
adjustment function. (Refer to 

P.54B-393

.)

Step 2. Check the operation of the hazard 
warning lamp.

Check that the hazard warning lamps illuminate 
normally.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Refer to inspection procedure K-2 "The 
hazard warning lamps do not illuminate 

P.54B-240

".

Step 3. Check the operation of the room lamps.

Check that the room lamps illuminate normally.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Refer to inspection procedure M-2 "The 
front or rear room lamp does not 
illuminate/extinguish 

P.54B-287

."

Step 4. Retest the system.

Check that the keyless entry hazard lamp 
answerback function or the room lamp answerback 
function work normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction
