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

−

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
