INSPECTION PROCEDURE 3: The System does not Recognize the Remote Controlled Radio Switch (RH) Only. < Vehicles with Seven Speakers >: Diagnosis

Required Special Tool: 

• MB991223: Harness set

1. STEP 1. Measure the resistance at remote controlled radio switch (RH). 
   1. Remove the air bag module (Refer to AIR BAG MODULE AND CLOCK SPRING < VEHICLES WITHOUT ADVANCED AIR BAG > or < VEHICLES WITH ADVANCED AIR BAG) >.
   2. Measure the resistance by operating the remote controlled radio switch (RH) in each position.

      RESISTANCE REFERENCE
      
      

      SWITCH POSITION	MEASUREMENT VALUE
      No push	Approximately 24.0 kΩ
      Upper	Approximately 6.8 kΩ
      Center	Less than 2 ohms
      Lower	Approximately 15.0 kΩ

   Q: Are the resistance at the right remote controlled radio switch normal? 

   1. YES  : Go to Step 2.
   2. NO  : Replace the remote controlled radio switch (RH).
2. STEP 2. Check the 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? 

   1. YES  : Go to Step 3.
   2. NO  : Repair or replace it. Refer to HARNESS CONNECTOR INSPECTION . The remote controlled radio switch (RH) should work normally.
3. 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? 

   1. YES  : The procedure is complete.
   2. NO  : Repair the wiring harness. The remote controlled radio switch (RH) should work normally.
