Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the right steering wheel control switch.
  2. Ignition OFF, test for less than 2.0 ohms between the low reference circuit terminal 3 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the SCCM.
  3. Ignition ON, test for 4.8-5.2 volts between the signal circuit terminal 6 and ground.
    • If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the SCCM.
    • If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the SCCM.
  4. If all circuits test normal, test or replace the right steering wheel control switch.
