Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the ESC module.
  2. Ignition OFF, test for less than 3 ohms between the ground circuit terminal 2 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 1 and ground
    • If the test lamp did not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the ESC module.
