Circuit/System Testing

PLUS and MINUS Switch Malfunction

1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the S16 Driver Information Center Switch, ignition ON.
2. Test for less than 10 Ω between the ground circuit terminal 7 and ground.
   • If 10 Ω or greater 

     Repair the open/high resistance in the circuit

   • If less than 10 Ω 
3. Test for 4.8-5.2 V between the signal circuit terminal 5 and ground.

   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 5.2 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 4.8-5.2 V 
4. Test for 4.8-5.2 V between the signal circuit terminal 6 and ground.
   • If less than 4.8 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 5.2 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 4.8-5.2 V 
5. Test or replace the S16 Driver Information Center Switch.

SELECT, CONFIG, and BACK Switch Malfunction

1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the S16 Driver Information Center Switch, ignition ON.
2. 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 
3. Test for 9.8-12.2 V between the signal circuit terminal 1 and ground.
   • If less than 9.8 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 12.2 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 9.8-12.2 V 
4. Test or replace the S16 Driver Information Center Switch.
