Step 7. Retest the system.

Replace the ETACS-ECU, and then check that the 
door-ajar warning lamp illuminates/extinguishes 
normally.
(1) Replace the ETACS-ECU.
(2) Check that the door-ajar warning lamp 

illuminates/extinguishes 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 

P.00-6

).

NO : 

Replace the combination meter.

DIAGNOSTIC PROCEDURE

Step 1. Connector check: C-217 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Measure the voltage at the C-217 
ETACS-ECU connector.

(1) Remove the ETACS-ECU, and measure at the 

junction block side.

(2) Ignition switch: ACC position

(3) Voltage between C-217 ETACS-ECU connector 

terminal No.18 and body earth

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Go to Step 3.

Step 3. Check the wiring harness between C-217 
ETACS-ECU connector terminal No.18 and the 
ignition switch (ACC).

NOTE: 

Prior to the wiring harness inspection, check junction 
block connector C-203, and repair if necessary.

•

Check the power supply line for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Repair the wiring harness.

Step 4. Retest the system.

Check that the ignition switch (ACC) signal is 
received normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−
