Circuit/System Testing
- Ignition OFF, disconnect the X1 harness connector at the EBCM.
- Test for less than 1.0 ohm between the ground circuit terminal 16 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, and the fuse is open, replace the EBCM.
- If all circuits test normal, replace the EBCM and verify DTC does not reset, if DTC reset replace the BPMV.
