CAUTIONCOMMENTS ON TROUBLE SYMPTOM
If the electric retractable remote controlled door mirror does not work at all, these
power supply circuit(s), these earth circuit(s), remote controlled mirror switch or ETACS-ECU
may be defective.POSSIBLE CAUSES
- Malfunction of the remote controlled mirror switch
- Malfunction of ETACS-ECU
- Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Pulse check
| System switch |
Check conditions |
|---|---|
| Ignition switch (ACC) |
When turned from the LOCK (OFF) position to the ACC position |
| Electric remote controlled mirror switch (folding/unfolding
switch) |
When the switch turned from off to on |
OK: The MUT-II/III sounds or the voltmeter needle fluctuates.
Q: Are the check result normal?
All the signals are received normally.:
Go to Step 2
.The ignition switch (ACC) signal is not received.: Refer to inspection procedure P-1 "The ignition switch (ACC) signal is not received
."The electric remote controlled mirror switch (folding/unfolding switch) signal is not received.: Refer to inspection procedure P-11 "Signal is not received from the electric remote controlled mirror switch (folding/unfolding switch)
."Step 3. Measure the voltage at the C-217 ETACS-ECU connector.
- Remove the ETACS-ECU, and measure at the junction block side.
- Check the voltage between the C-217 ETACS-ECU connector terminal No.2 and body earth.
OK: Battery positive voltage
Q: Is the check result normal?
YES:
Go to Step 5.NO: Go to Step 4
.Step 4. Check the wiring harness between C-217 ETACS-ECU connector
terminal No. 2 and the fusible link (1).
NOTE: Prior to the wiring harness inspection, check intermediate connectors A-14, C-125 and
junction block connector C-204, and repair if necessary.
- Check the power supply line to the battery 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 ).NO: Repair the wiring harness.
