   1. 

      *a	Component without harness connected (Steering Pad Switch Assembly)	*b	Seek+
      *c	Seek-	*d	Volume+
      *e	Volume-	*f	MODE
      *g	Off Hook	*h	On Hook
      *i	Voice	*j	Up
      *k	Down	*l	Left
      *m	Right	*n	Enter
      *o	Back	*p	Top
      *q	Terminal-A	-	-

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition z4-2 (+DP) - z4-8 (EAU) No switch pushed 95 to 105 kΩ Enter switch pushed Below 2.5 Ω Top switch pushed 313 to 345 Ω Back switch pushed 950 to 1050 Ω z4-3 (+DP2) - z4-8 (EAU) No switch pushed 95 to 105 kΩ Left switch pushed Below 2.5 Ω Up switch pushed 313 to 345 Ω Down switch pushed 950 to 1050 Ω Right switch pushed 2955 to 3265 Ω z4-10 (AU2) - z4-8 (EAU) No switch pushed 95 to 105 kΩ MODE switch pushed Below 2.5 Ω On hook switch pushed 313 to 345 Ω Off hook switch pushed 950 to 1050 Ω Voice switch pushed 2955 to 3265 Ω z4-11 (AU1) - z4-8 (EAU) No switch pushed 95 to 105 kΩ Seek+ switch pushed Below 2.5 Ω Seek- switch pushed 313 to 345 Ω Volume+ switch pushed 950 to 1050 Ω Volume- switch pushed 2955 to 3265 Ω z4-6 (HO) - Terminal-A Always Below 2.5 Ω z4-7 (ECC) - z20-1 (ECC) Always Below 2.5 Ω z4-12 (CCS) - z20-3 (CCS) Always Below 2.5 Ω

      Tip:

      If the result is not as specified, replace the steering pad switch assembly.

   2. 

      *a

      Component without harness connected (Steering Pad Switch Assembly)

      -

      -

      Check the illumination.

      
      

      1. Connect a positive (+) lead from the battery terminal z4-5 (IL+2) and a negative (-) lead to terminal z4-8 (EAU) of the steering pad switch assembly connector.

      2. Check that the steering pad switch assembly illumination illuminates.

         OK
         The steering pad switch assembly illumination illuminates.

         Tip:

         If the result is not as specified, replace the steering pad switch assembly.
