Step 15. Check the wiring harness between C-220
ETACS-ECU connector terminal Nos.31, 40 and
F-13 door mirror assembly (RH) connector
terminal Nos.7, 6.

NOTE:

Prior to the wiring harness inspection, check
intermediate connector C-14 and junction block
connector C-32 <L.H drive vehicles>, and repair if
necessary.

• Check the input and output signal line for open

circuit.

Q: Is the check result normal?

YES :

Go to Step 16.

NO :

Repair the wiring harness.

Step16. Retest the system.
Check that the electric retractable remote controlled
mirror works 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

Inspection Procedure J-3: Electric retractable remote controlled door mirror timer function does not
at all.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

If the door mirror can be folded and unfolded with the
remote controlled mirror switch (fold/unfold switch),
the ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the driver’s door switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the electric folding door mirrors
operation.
Check that the door mirror is folded and unfolded
with the remote controlled mirror switch when the
ignition switch is at ACC position.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Refer to inspection procedure J-1 "The
electric retractable remote controlled door
mirrors does not work at all

P.54B-250

."

Step 2. Pulse check
Check the input signals below which are related to
the electric retractable remote controlled door mirror
timer function.

OK: The MUT-III sounds or the voltmeter
needle fluctuates.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Refer to inspection procedure Q-1 "The
ignition switch (ACC) signal is not received

P.54B-416

."

Step 3. Retest the system.
Check that the electric-folding door mirror timer
function works 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.00-5

).

NO :

Replace the ETACS-ECU.
