INSPECTION PROCEDURE 3: Remote controlled radio switch: The system does not recognize the remote controlled radio switch (RH) only. < Vehicles with audio amplifier>: Diagnosis

Required Special Tools: 

• MB991223: Harness set
• MB992006: Extra Fine Probe

1. STEP 1. Measure the resistance at remote controlled radio switch (RH). 
   1. Remove the airbag module assembly (Refer to AIR BAG MODULE(S) AND CLOCK SPRING ).
   2. Measure the resistance by operating the remote controlled radio switch (RH) in each position.
   RESISTANCE SPECIFICATION
   
   

   SWITCH POSITION	MEASUREMENT VALUE
   No push	Approximately 24.0 kΩ
   Upper	Approximately 5.3 kΩ
   Center	Less than 2 ohms
   Lower	Approximately 9.2 kΩ

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

   YES:  Go to Step  2.

   NO:  Replace the remote controlled radio switch (RH).

2. 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 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 (terminals 1 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 radio switch (RH) should work normally.
