Inspection [08/2014 - ]: Procedure
- INSPECT STEERING PAD SWITCH ASSEMBLY
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition z4-1 (HO) - A-1 (HO) Always Below 2.5 Ω z4-4 (DIST) - z4-7 (ECC) No switch pushed 1 MΩ or higher Distance control switch pushed*1 Below 2.5 Ω z4-2 (+DP) - z4-3 (-DP) No switch pushed 1 MΩ or higher DISP switch pushed Below 2.5 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 z4-10 (AU2) - z4-8 (EAU) No switch pushed 95 to 105 kΩ MODE switch pushed Below 2.5 Ω Voice switch pushed 2955 to 3265 Ω On hook switch pushed 313 to 345 Ω Off hook switch pushed 950 to 1050 Ω - *1: w/ Dynamic Radar Cruise Control System

- Disconnect the steering pad switch assembly connector.
- Check that the steering pad switch assembly illuminates according to the table below.
OK
Connection Specified Condition Auxiliary battery positive (+) → 5 (IL+2)
Auxiliary battery negative (-) → 8 (EAU)Switches of steering pad switch LH side illuminates Auxiliary battery positive (+) → 5 (IL+2)
Auxiliary battery negative (-) → 3 (-DP)Switches of steering pad switch RH side illuminates HINT:
If the result is not as specified, replace the steering pad switch assembly.
