Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector of the module that set the DTC.
  2. Verify that there is less than 1.0 ohm between the ground circuit and the negative battery terminal.
    • 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 of the appropriate module 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 appropriate control module.
