Circuit/System Testing

NOTE:

Circuit/System Verification must be performed before proceeding with Circuit/System Testing.

Set, Up and Down Switch Malfunction

Ignition OFF and all vehicle systems OFF, disconnect the X1 harness connector at the S48A multifunction switch, ignition ON.
Test for less than 10 Ω between the low reference circuit terminal 6 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
Test for 11.8-12.2 V between the signal circuit terminal 12 and ground.
- If less than 11.8 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 11.8-12.2 V
Test or replace the S48A multifunction switch.
