Component Testing
CAUTION:
Refer to SIR Caution
.
- Ignition OFF, disconnect the harness connector at the audio steering wheel control switches.
- Test the switch for infinite resistance between the voltage supply terminal and the signal terminal with the switch in the open position.
- If less than infinite resistance, replace the switch.
- Test resistance values between the voltage supply terminal and the signal terminal with the switch closed in each position and verify readings are approximate to what the schematic reads.
- If values do not, replace the switch.
