Circuit/System Testing
- Ignition OFF, disconnect the EBCM connector.
- Ignition ON, check for 11-14V between the B+ circuit and ground.
- If the voltage is not as specified, test the B+ circuit for a short to ground or an open/high resistance.
- Test for less than 1 ohm between the ground circuits and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the BPMV/EBCM.
