Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the I/P multifunction switch.
  2. Ignition ON, verify the scan tool CDLS Switch Status parameter is Off.
    • If not the specified value, test the signal circuit terminal 5 for a short to ground. If the circuit tests normal, replace the instrument panel cluster.
  3. Connect a 3A fused jumper wire between the signal circuit terminal 5 and ground, verify the CDLS Switch Status parameter is On.
    • If not the specified value, test the signal circuit for a short to voltage or and open/high resistance. If the circuit tests normal, replace the instrument panel cluster.
  4. If all circuits test normal, test or replace the I/P multifunction switch.
