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

STEP 2. M.U.T.-III data list
Check the signal related to the operation of ignition
key cylinder illumination lamp.

• Turn the ignition switch to the LOCK "(OFF)"

position.

• Remove the ignition key from the ignition key cyl-

inder.

.

STEP 3. Check of open circuit in LP+3 line key
reminder 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 of ignition key cylinder
illumination lamp bulb
Check that the ignition key cylinder illumination lamp
bulb is normal.

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Replace the bulb of the ignition key cylinder
illumination lamp.

STEP 5. Check of open circuit in earth line
between key reminder switch connector and
body earth.

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the connector(s) or wiring harness.

STEP 6. Check of open circuit in (RLP-1,

STEP 7. Retest the system
Check that the ignition key cylinder illumination lamp
illuminates/extinguishes normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

use Troubleshooting/inspection Service

Malfunction ).

NO :

Replace the ETACS-ECU.

Inspection Procedure 2: Malfunction of the ignition switch power supply system

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

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 ignition switch

• 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?

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

Cope with Intermittent Malfunction ).

NO :

Replace the ETACS-ECU.
