Circuit/System Testing

Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the K60 Steering Column Lock Module. It may take up to 5 minutes for all vehicle systems to power down.
Test for less than 3 V between the control circuit terminal 2 and ground.
- If 3 V or greater
1. Disconnect the harness connector at the K9 Body Control Module. Ignition ON.
  NOTE: For vehicles with push button start, it is necessary to back out the terminal for the steering column lock status signal circuit at the K9 Body Control Module harness. When the harness connector is removed, the vehicle cannot be put back into an Ignition ON state.
2. Test for less than 3 V between the control circuit terminal 2 and ground.
  - If 3 V or greater, repair the short to voltage on the circuit.
  - If less than 3 V, replace the K9 Body Control Module.
- If less than 3 V
Ignition ON.
Test for B+ between the control circuit terminal 2 and ground.
- If less than B+
1. Disconnect the harness connector at the K9 Body Control Module.
2. Test for infinite resistance between the signal circuit terminal 2 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 terminal 2 end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω
4. Replace the K9 Body Control Module.
- If B+
Replace the K60 Steering Column Lock Module.
