Circuit/System Testing

Ignition OFF, disconnect the harness connector at the EBCM.
Test for less than 1 Ω between the ground circuits listed below and ground.
- Terminal 13
- Terminal 38
- If greater than the specified range, test the ground circuits for an open/high resistance.
Ignition ON, verify that a test lamp illuminates between the B+ circuits listed below and ground.
- Terminal 1
- Terminal 25
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
If all circuits test normal, replace the EBCM.
