Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Ignition OFF, disconnect the harness connector at the appropriate Engine Mount Solenoid Valve.
- Verify a test lamp illuminates between the ignition circuit terminal 2 and ground.
- If the test lamp does not illuminate and the circuit fuse is good
- Ignition OFF, remove the test lamp.
- Test for less than 2 Ω in the ignition circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, verify the fuse is not open and there is voltage at the fuse. Refer to Power Mode Mismatch
- If the test lamp does not illuminate and the circuit fuse is open
- Ignition OFF, remove the test lamp.
- Test for infinite resistance between the ignition circuit and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance, replace the appropriate Engine Mount Solenoid Valve.
- Go to next step: If the test lamp illuminates
- Connect a test lamp between the control circuit terminal 1 and the ignition circuit terminal 2.
- Verify the test lamp turns On and Off when commanding the Driveline Mount Output 1 and 2 On and Off with a scan tool.
- If the test lamp is always Off
- Ignition OFF, remove the test lamp, disconnect the harness connector at the K38 Chassis Control Module, ignition ON.
- Test for less than 1 V between the control circuit and ground.
- If 1 V or greater, repair the short to voltage on the circuit.
- Go to next step: If less than 1 V
- Ignition OFF.
- Test for less than 2 Ω in the control circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, replace the K38 Chassis Control Module.
- If the test lamp is always On
- Ignition OFF, remove the test lamp, disconnect the harness connector at the K38 Chassis Control Module.
- Test for infinite resistance between the control circuit and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance, replace the K38 Chassis Control Module.
- Go to next step: If the test lamp turns On and Off
- Test or replace the appropriate Engine Mount Solenoid Valve.
