SYMPTOM PROCEDURES

Inspection Procedure 1: The ignition key cylinder illumination lamp does not illuminate/extinguish 
normally.

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

.)

OPERATION

The ETACS-ECU operates this function in accord-
ance with the input signals below.

• Ignition switch (IG1)

• Key reminder switch

• Driver's door switch

• Driver's door lock actuator

COMMENTS ON TROUBLE SYMPTOM

If this function does not work normally, these input 
signal circuit(s), the ignition key cylinder illumination 
lamp or the ETACS-ECU may be defective.

PROBABLE CAUSES

• Malfunction of the key reminder switch

• Malfunction of the driver's door switch

• Malfunction of the driver's door lock actuator

• Malfunction of the ignition key cylinder illumina-

tion lamp bulb

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

COMMENTS ON TROUBLE SYMPTOM

When the power supply system of ignition switch has 
a problem, none of the equipment and system con-
nected to the ignition switch works even if the ignition 
switch is operated.

• Malfunction of the fuse

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. Voltage measurement at ignition switch 
connector
(1) Disconnect the ignition switch connector and 

measure the voltage at ignition switch connector 
harness side.

(2) Check the voltage between the ignition switch 

connector (power supply terminal) and body 
earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Go to Step 2.

STEP 2. Check the fuse.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the fuse. (Check that there is not a 
short to earth in the circuit of lower reaches 
before replacing. If there are any problems, 
replace the fuse after the circuit of lower 
reaches is repaired.)

STEP 3. Check of open circuit in IG+ line between 
ignition switch connector and ETACS-ECU 
connector.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the connector(s) or wiring harness.

STEP 4. Check the ignition switch.
Refer to 

P.54A-19

.

Q: Is the ignition switch in good condition?

YES : 

Go to Step 5.

NO : 

Replace the ignition switch.

STEP 5. Retest the system.

Q: Do the device and the system work normally when 

the ignition switch is operated?
YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction ).

NO : 

Replace the ETACS-ECU.
