51 -EXTERIOR > OUTSIDE MIRROR > TROUBLESHOOTING > VEHICLE SPEED-DEPENDENT UNFOLDING FUNCTION DOES NOT WORK NORMALLY
Inspection Procedure 4: Vehicle speed-dependent unfolding function does not work normally.
 
 
caution
  • Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
 
 
 
 
 
OPERATION
The ETACS-ECU calculates the intermittent wiper interval according to the vehicle speed signal which is sent by the ASC-ECU.
  • Ignition switch (IG1)
 
 
 
COMMENTS ON TROUBLE SYMPTOM
If this function does not work normally, these input signal circuit(s) or the ETACS-ECU may be defective. Also, with a customise function, the door mirrors may be set to a mode in which the vehicle speed-dependent unfolding function is not activated.
 
 
 
PROBABLE CAUSES
  • Faulty vehicle speed signal
  • The CAN bus line is defective.
  • Malfunction of ETACS-ECU
 
 
 
 
DIAGNOSTIC PROCEDURE
STEP 1. Check the ETACS customise function.
Use the ETACS customise function to confirm that "AUTO FOLD MIRROR" is set to "OPEN VEHICLE SPD".
Is the check result normal?
Go to Step 2.
Use the ETACS customise function to set "AUTO FOLD MIRROR" to "OPEN VEHICLE SPD" (Refer to ).
 
STEP 2. M.U.T.-IIISE CAN bus diagnostics
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the CAN bus normal?
Go to Step 3.
Repair the CAN bus line (Refer to GROUP 54C, Troubleshooting ).
 
STEP 3. M.U.T.-IIISE diagnosis code.
Check that the ETACS-ECU sets a diagnosis code.
Is the diagnosis code set?
Diagnose the ETACS (Refer to GROUP 54A, ETACS - Diagnosis Code Chart ).
Go to Step 4.
 
STEP 4. M.U.T.-IIISE other system diagnosis code
Check that the ASC-ECU sets a diagnosis code.
Is the diagnosis code set?
Diagnose the ASC-ECU (Refer to GROUP 35C, Diagnosis Code Chart ).
Go to Step 5.
 
STEP 5. Retest the system.
Check that the vehicle speed-dependent unfolding function of the door mirrors works normally.
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Replace ETACS-ECU.
