51 -EXTERIOR > OUTSIDE MIRROR > TROUBLESHOOTING > ELECTRIC RETRACTABLE REMOTE CONTROLLED DOOR MIRROR DOES NOT WORK AT ALL
Inspection Procedure 1: Electric-folding door mirrors do not work at all.
| caution | - Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
|
OPERATION
The ETACS-ECU operates this function in accordance with the input signals below.
- Ignition switch (ACC)
- Electric remote controlled mirror switch (folding/unfolding switch)
COMMENTS ON TROUBLE SYMPTOM
If the system does not work, the input circuit from the ignition switch (ACC) or the remote controlled mirror switch (folding/unfolding switch), or the ETACS-ECU may be faulty.
PROBABLE CAUSES
- Defective remote controlled mirror switch
- Defective ignition switch (ACC)
- Malfunction of ETACS-ECU
- Damaged wiring harness and connectors
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
STEP 2. M.U.T.-IIISE data list
Check the input signals which are related to the electric folding door mirrors.- Ignition switch: ACC
- Electric remote controlled mirror switch (folding/unfolding switch): ON
| | | Item No. | Item name | Normal conditions | | 91 | Mirror switch | ON | | 111 | ACC switch | ON |
|
OK: Normal conditions are displayed for all the items.
Is the check result normal?
Normal conditions are displayed for all the items. : Go to Step 3
. Normal condition is not displayed for item No. 91. : Refer to GROUP 54A - ETACS, Inspection Procedure 13 "The remote controlled mirror switch (fold switch) signal is not received." . Normal condition is not displayed for item No. 111. : Refer to GROUP 54A - ETACS, Inspection Procedure 1 "The ignition switch (ACC) signal is not received." .
STEP 3. M.U.T.-IIISE data list
Check the data list which are related to the electric folding door mirrors.- Turn on the folding/unfolding switch when the door mirrors are folded.
| | | Item No. | Item name | Normal conditions | | 71 | Fold mirror open | ON | | 72 | Fold mirror close | OFF |
|
- Turn on the folding/unfolding switch when the door mirrors are unfolded.
| | | Item No. | Item name | Normal conditions | | 71 | Fold mirror open | OFF | | 72 | Fold mirror close | ON |
|
OK: Normal condition is displayed.
Is the check result normal?
Go to Step 5.
Go to Step 4.
STEP 4. Check of short to power supply, short to earth, and open circuit in +B2 line between fusible link and ETACS-ECU connector
Is the check result normal?
Go to Step 5. Repair the connector(s) or wiring harness.
STEP 5. Retest the system.
