Circuit/System Testing
- Ignition OFF, disconnect the EBCM connector.
- Test for infinite resistance between the CSW circuit and ground.
- If less than the specified range, test the circuit for a short to ground. If circuit tests normal, replace the VSC switch.
- Using a scan tool, command the IPC display test ON and OFF. The VSC warning indicator should turn ON and OFF.
- If IPC does not perform as specified, replace the IPC.
- If IPC performs as specified, replace the BPMV/EBCM.
