Component Testing
CAUTION:
Refer to SIR Caution
in Cautions and Notices.
- Ignition OFF, disconnect the harness connector at the audio steering wheel control switch.
- Test for infinite resistance between the 10-volt reference 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 10-volt reference 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.
