the wiring harness, connectors, back-up lamp switch
or multivision display may be defective.
PROBABLE CAUSES
• Damaged harness wires and connectors
• Malfunction of the back-up lamp switch <M/T>
• Malfunction of the inhibitor switch <CVT, A/T>
• Malfunction of the rear view camera
• Malfunction of the multivision display
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III other system diagnosis code
Check again if the diagnosis code is set to the
ETACS-ECU.
Q: Is the diagnosis code set?
YES :
Diagnose the ETACS-ECU (Refer to
GROUP 54A
− ETACS-ECU −
Troubleshooting ).
NO :
Go to Step 2.
STEP 2. M.U.T.-III data list
Check if ETACS-ECU related signal is set.
• Turn the ignition switch to the ON position.
OK: Normal condition is displayed.
Q: Is the check result normal?
