54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > ETACS > INPUT SIGNAL PROCEDURES > THE REMOTE CONTROLLED MIRROR SWITCH SIGNAL IS NOT RECEIVED
Inspection Procedure 13: The remote controlled mirror switch (fold switch) signal is not received.
 
 
caution
  • Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
COMMENTS ON TROUBLE SYMPTOM
Input signal from the remote controlled mirror switch (fold switch) is used to operate the functions below. If the signal is abnormal, these functions will not work normally.
  • Electric-folding door mirrors
 
 
PROBABLE CAUSES
  • Malfunction of the remote controlled mirror switch
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check the remote controlled mirror switch.
Refer to GROUP 51 - Door Mirror .
Is the check result normal?
Go to Step 2.
Replace the remote controlled mirror switch.
 
STEP 2. Resistance measurement at remote controlled mirror switch connector (earth terminal)
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the remote controlled mirror switch connector (earth terminal) and body earth.
OK: Continuity exists (2 Ω or less)
Is the check result normal?
Go to Step 4.
Go to Step 3.
 
STEP 3. Check of open circuit in earth line between remote controlled mirror switch connector and body earth
Is the check result normal?
Intermittent malfunction is suspected (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Repair the connector(s) or wiring harness.
 
STEP 4. Check of short to power supply, short to earth, and open circuit in MRR line between ETACS-ECU connector and remote controlled mirror switch connector
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. M.U.T.-IIISE data list
Check the input signals from the remote controlled mirror switch (fold switch).
  • Operate the remote controlled mirror switch (fold switch).
 
Item No.Item nameNormal condition
91Mirror switchOFF to ON (only when switch is operated)
OK: Normal condition is displayed.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
Replace the ETACS-ECU.
