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.
  1. Remove the ETACS-ECU, and measure at the junction block side.
  1. Check the voltage between the C-217 ETACS-ECU connector terminal No.2 and body earth.
    2. 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.
