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 

Connector Inspection 

P.00E-2

. The remote controlled 

radio switch (RH) should work normally.

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
