Circuit/System Testing

Vehicle OFF, disconnect the harness connector at the S16 driver information center switch.
Test for less than 10 Ω between the low reference circuit terminal 2 and ground.
- If 10 Ω or greater
1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster.
2. Test for less than 2 Ω in the low reference circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the P16 Instrument Cluster.
- If less than 10 Ω
Vehicle ON.
Test for less than 1 V between the low reference circuit terminal 2 and ground.
- If 1 V or greater, repair the short to voltage on the circuit.
- If less than 1 V
Test for 10-12 V between the signal S16 Driver Information Center Switch signal circuit terminal 1 and ground.
- If less than 10 V
1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster.
2. Test for infinite resistance between the signal circuit and ground.
  - If less than infinite resistance, repair the short to ground on the circuit.
  - If infinite resistance
3. Test for less than 2 Ω in the signal circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the P16 Instrument Cluster.
- If greater than 12 V
1. Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster, ignition ON.
2. Test for less than 1 V between the signal circuit and ground.
  - If 1 V or greater, repair the short to voltage on the circuit.
  - If less than 1 V, replace the P16 Instrument Cluster.
- If between 10-12 V
Test or replace the S16 Driver Information Center Switch.
