STEP 4. Measure the resistance at remote controlled radio 
switch ground circuit to the clock spring connector C-306.
(1) Disconnect the clock spring connector C-306.

(2) Measure resistance between terminal 3 and ground.

• The measured value should be 2 ohm or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 7.
NO :  Go to Step 5.

STEP 5. Check radio, CD player and CD changer connector 
C-117 and clock spring connector C-306 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are radio, CD player and CD changer connector C-117 

and clock spring connector C-306 in good condition?
YES : Go to Step 6.
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 6. Check the wiring harness between radio, CD 
player and CD changer connector C-117 (terminal 25) and 
clock spring connector C-306 (terminal 3).
Q: Is the wiring harness between radio, CD player and CD 

changer connector C-117 (terminal 25) and clock spring 
connector C-306 (terminal 3) in good condition?
YES : Go to Step 7.
NO :  Repair the wiring harness. The remote controlled 

radio switch should work normally.

STEP 7. Measure the resistance between the clock spring 
connector C-306 terminals.
(1) Disconnect the clock spring connector C-306.

(2) Measure the resistance between clock spring connector 

C-306 (clock spring side) terminals 2 and 3. Operate the 
right and left remote controlled radio switches, and check 
that the table below is satisfied.

NOTE: When checking the right remote controlled radio 
switch, do not operate the left remote controlled radio 
switch.

Q: Is the resistance between terminals 2 and 3 normal?

YES : This malfunction is intermittent. Refer to GROUP 00, 

How to Use Troubleshooting/Inspection Service 
Points-How to Cope with Intermittent Malfunction 

P.00-14

.

NO :  Go to Step 8.

STEP 8. Measure the resistance at clock spring terminal.
(1) Remove the clock spring (Refer to GROUP 52B, Air Bag 

Module(s) and Clock Spring 

P.52B-237

).

(2) Measure the resistance at clock spring connectors C-303 

and C-306.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 9.
NO :  Replace the clock spring.
