Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
    IMPORTANT: You must perform the Circuit/System Verification before proceeding with Circuit/System Testing.
  1. Ignition OFF, disconnect the 14-volt and 42-volt harness connectors at the APM.
  2. Test for less than 1.0 ohm between the APM chassis and ground.
    • If greater than the specified value, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit connector X3 terminal 1 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the APM.
