audio remote control switch connector C-213 (terminal 2, 
4) and clock spring connector C-202 (terminal 5, 4).

• Check the communication lines for open or short circuit.

Q: Is the wiring harness between steering wheel audio 

remote control switch connector C-213 (terminal 2, 4) 
and clock spring connector C-202 (terminal 5, 4) in good 
condition?
YES : 
Go to Step 8.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary.

STEP 8. Retest the system
Check whether you can operate the multivision display by 
using the steering remote control.
Q: Is the check result normal?

YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00, How to use 
Troubleshooting/inspection Service Points, How to 
Cope with Intermittent Malfunction 

P.00-15

).

NO :  Replace the multivision display.
