NO : Repair or replace the damaged component (Refer to
GROUP 00E, Harness Connector Inspection
). The steering wheel audio remote control
switch should work normally.
STEP 3. Check the clock spring.
Check whether the clock spring is in good condition (Refer to
GROUP 52B, Driver’s air bag module and clock spring
).
Q: Is the check result normal?
YES : Go to Step 4.
NO : Replace the clock spring.
STEP 4. Check multivision display connector C-10 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is multivision display connector C-10 in good
condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component (Refer to
GROUP 00E, Harness Connector Inspection
). The steering wheel audio remote control
switch should work normally.
STEP 5. Check the wiring harness between multivision
display connector C-10 (terminal 43, 59) and clock spring
connector C-205 (terminal 2, 3).
NOTE: Also check intermediate connector C-108, C-32 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connector C-108, C-32 is
damaged, repair or replace the connector as described in
GROUP 00E, Harness Connector Inspection
• Check the communication lines for open or short circuit.
Q: Is the wiring harness between multivision display
connector C-10 (terminal 43, 59) and clock spring
connector C-205 (terminal 2, 3) in good condition?
YES : Go to Step 6.
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.

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
NO : Replace the multivision display.
