Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the S78 Turn Signal/Multi-Function Switch.
  2. Ignition ON, test for greater than 4.8 V between the harness connector signal circuit terminal 5 and ground.
    • If less than the specified range, test the signal circuit for a short to ground. If the circuit tests normal replace the P16 Instrument Cluster.
  3. Test for greater than 11 V between the signal S78 Turn Signal/Multi-Function Switch circuit terminal 12 and ground.
    • If not within the specified range, test the signal for an open/high resistance or a short to ground. If the circuit tests normal replace the P16 Instrument Cluster.
  4. Install a 5 A fused jumper wire between the signal S78 Turn Signal/Multi-Function Switch circuit terminal 12 and the low reference circuit terminal 6. Verify the scan tool Driver Information Center Switch parameter displays 0 V.
    • If not the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal replace the P16 Instrument Cluster.
  5. If all circuits tests normal, replace the S78 Turn Signal/Multi-Function Switch.
