Steering Pad Switch: Inspection
- INSPECT STEERING PAD SWITCH LH
- Measure the resistance according to the values in the table below.
Standard resistance
STEERING PAD SWITCH LHTester connection Condition Specified condition AU1 - EAU No switch is pushed Approx. 100 kΩ AU1 - EAU SEEK+ switch: push Approx. 0 Ω AU1 - EAU SEEK- switch: push Approx. 0.3 kΩ AU1 - EAU VOL+ switch: push Approx. 1 kΩ AU1 - EAU VOL- switch: push Approx. 3.1 kΩ AU2 - EAU No switch is pushed Approx. 100 kΩ AU2 - EAU MODE switch: push Approx. 0 Ω If the result is not as specified, replace the steering pad switch LH.
- INSPECT STEERING PAD SWITCH CABLE SUB-ASSEMBLY (w/ Navigation System)
- Disconnect the steering pad switch LH and the steering pad switch RH.
- Measure the resistance according to the values in the table below.
