YES : 

Replace the headlamp assembly that does 

not illuminate.

NO : 

Repair the connector(s) or wiring harness.

Inspection Procedure 6: The high-beam indicator lamp does not illuminate.

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

If the high-beam indicator does not illuminate nor-
mally, the harness in the CAN bus lines, connec-
tor(s), ETACS-ECU, or combination meter may have 
a problem.

PROBABLE CAUSES

• Malfunction of the ETACS-ECU

• Malfunction of combination meter

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

ance with the input signals from driving distance, 
lighting control sensor, and column switch (auto lamp 
switch). Also, when the column switch (lighting 
switch) is in the "AUTO" position, and when an 
abnormality is present to the auto lamp circuit, the 
fail-safe function is activated and the low beam is 
turned ON at all times regardless of the brightness 
around the vehicle.

COMMENTS ON TROUBLE SYMPTOM

If the auto lamp function does not work normally, the 
above input signal circuit(s) or the ETACS-ECU may 
have a problem.

PROBABLE CAUSES

• Malfunction of the lighting control sensor

• Malfunction of the column switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors
