STEP 2. Check clock spring connector C-202 and C-204 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are clock spring connector C-202 and C-204 in good

condition?
YES : Go to Step 3.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. 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, Air bag module and clock spring

P.52B-447

.

Q: Is the check result normal?

YES : Go to Step 4.
NO : Replace the clock spring.

STEP 4. Check multivision display connector C-07 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is multivision display connector C-07 in good

condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. The steering wheel audio remote control

switch should work normally.

STEP 5. Check the wiring harness between multivision
display connector C-07 (terminal 53, 69) and clock spring
connector C-204 (terminal 2, 3).
NOTE: Also check intermediate connector C-17 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-17 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

• Check the communication lines for open and short circuit.

Q: Is the wiring harness between multivision display

connector C-07 (terminal 53, 69) and clock spring
connector C-204 (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.

STEP 6. Check steering wheel audio remote control switch
connector C-213 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Is steering wheel audio remote control switch

connector C-213 in good condition?
YES : Go to Step 7.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. The steering wheel audio remote control

switch should work normally.

STEP 7. Check 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).

• Check the communication lines for open and 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 wheel audio remote control switch.
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

).
