Component Testing

CAUTION: Refer to SIR Caution .
  1. Ignition OFF, disconnect the harness connector at the suspect audio steering wheel control switch.
  2. Test the right switch for 2360-2400 ohms of resistance between the supply voltage terminal and the supply voltage terminal for the left switch.
    • If the resistance is not between 2360-2400 ohms, replace faulty switch.
  3. Test the switch for infinite resistance between the supply voltage terminal and the signal terminal with the switch in the open position.
    • If less than infinite resistance, replace the switch.
  4. Test resistance values between the supply voltage 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.
