ELECTRIC RETRACTABLE REMOTE CONTROLLED DOOR MIRROR

INSPECTION PROCEDURE I-1: Electric retractable remote controlled door mirror does not work at all.
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS 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. ECU check on the SWS monitor Check that the power supply and earth lines to the ETACS-ECU and the SWS communication lines are normal. Ignition switch: OFF ECUS TO BE CHECKED ETACS ECU OK: "OK" is displayed on the "ETACS ECU" menu. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure A-3 "Communication with the ETACS-ECU is not possible ."
| Step 2. Confirm communication data by using the SWS monitor. Check the SWS communication signal, which are related to the electric retractable remote controlled mirror. <Selected item> ETACS ECU Ignition switch: ACC
Item No. | Item name | Normal conditions
--- | --- | ---
Item 31 | IG SW (ACC) | ON
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 3. NO: Refer to inspection procedure P-1 "The ignition switch (ACC) signal is not received ."
| Step 3. Check the ETACS SW data by using the SWS monitor. Check the ETACS-ECU signal, which is related to the electric retractable remote controlled mirror. Electric remote controlled mirror switch (folding/unfolding switch): ON
Item No. | Item name | Normal conditions
--- | --- | ---
Item 14 | EL RET MIR SW | ON
OK: Normal condition is displayed Q: Is the check result normal? YES: Go to Step 4. NO: Refer to inspection procedure P-11 "Signal is not received from the electric remote controlled mirror switch (folding/unfolding switch) ."
| Step 4. Connector check: C-217 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 5. NO: Repair the connector.
| Step 5. 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 7. NO: Go to Step 6.
| Step 6. 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.
| Step 7. 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 ). NO: Replace the ETACS-ECU.
