operate the functions below. If the signal is abnormal,
these functions will not work normally.

•

Lamp reminder function

•

Ignition key cylinder illumination lamp

•

Headlamp automatic-shutdown function

•

Turn signal lamp

•

Room lamps

POSSIBLE CAUSES

•

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: ON position

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

terminal No.8 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.8 and the
ignition switch (IG1).

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 (IG1) signal is received
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 ETACS-ECU.

INSPECTION PROCEDURE N-3: The back-up lamp switch signal is not received. <M/T>

CAUTION

Whenever the ECU is replaced, ensure that the
input signal circuit is normal.

COMMENTS ON TROUBLE SYMPTOM
Input signal from the back-up lamp switch is used to
operate the rear wiper. If the signal is abnormal, the
rear wiper will not work normally.

POSSIBLE CAUSES

•

Malfunction of the back-up lamp switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors
