Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the EBCM.
- Ignition OFF, test for less than 5.0 ohms between the ground circuit terminals listed below and ground.
- If greater than the specified range, test the ground circuits for an open/high resistance.
- Ignition ON, verify a test lamp illuminates between the B+ circuits listed below and ground.
- Terminal A
- Terminal B
- Terminal C
- If test did not illuminate, test the B+ circuits for a short to ground or an open/high resistance.
- If the circuits test normal, replace the EBCM.
