STEP 9. Check the clock spring connector C-303 and
remote controlled radio switch (RH) connector C-301 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are clock spring connector C-303 and remote controlled

radio switch (RH) connector C-301 in good condition?
YES : Go to step 10.
NO : Repair or replace the component(s). Refer to GROUP

00E, Harness Connector Inspection

P.00E-2

. The

remote controlled radio switch should work normally.

STEP 10. Check the wiring harness between clock spring
connector C-303 (terminals 4 and 5) and remote controlled
radio switch (RH) connector C-301 (terminals 1 and 2).
Q: Is the wiring harness between clock spring connector

C-303 (terminals 4 and 5) and remote controlled radio
switch (RH) connector C-301 (terminals 1 and 2) in good
condition?
YES : Go to Step 11.
NO : Repair the wiring harness. The remote controlled

radio switch should work normally.

STEP 11. Measure the resistance at remote controlled
radio switch (RH).
(1) Remove the airbag module assembly (Refer to GROUP

52B, Air Bag Module(s) and Clock Spring

P.52B-237

).

(2) Measure the resistance by operating the remote controlled

radio switch (RH) in each position.

Q: Are the resistance at the right remote controlled radio

switch normal?
YES : Replace the radio, CD player and CD changer.
NO : Replace the remote controlled radio switch (RH).

INSPECTION PROCEDURE 3: The system does not recognize the remote controlled radio switch (RH)
only.

STEP 2. Check the remote controlled radio switch (RH)
connector C-301 and clock spring connector C-303 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is remote controlled radio switch (RH) connector C-301

and clock spring connector C-303 in good condition?
YES : Go to Step 3.
NO : Repair or replace it. Refer to GROUP 00E, Harness

. The remote controlled

radio switch (RH) should work normally.

STEP 3. Check the wiring harness between remote
controlled radio switch (RH) connector C-301 (terminals1
and 2) and clock spring connector C-303 (terminals 4 and
5).
Q: Are the wiring harness between remote controlled radio

switch (RH) connector C-301 (terminals 1 and 2) and
clock spring connector C-303 (terminals 4 and 5) in
good condition?
YES : The procedure is complete.
NO : Repair the wiring harness. The remote controlled
