Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the ESC module.
- Ignition OFF, test for less than 5 Ω between the ground circuit terminal 47 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 32 and ground.
- 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 ESC module.
