Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the K64 Theft Deterrent Module.
  2. Ignition OFF, test for less than 10Ω between the low reference circuit terminal 1 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K64 Theft Deterrent Module.
  3. Ignition ON, test for B+ between the ignition circuit terminal 3 and ground.
    • If not the specified value, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K64 Theft Deterrent Module.
  4. Ignition OFF, disconnect the X3 harness connector at the K9 Body Control Module.
  5. Ignition ON, test for less than 1 V between the signal circuit terminal 2 at the K9 Body Control Module harness connector and ground.
    • If greater than the specified range, test the signal circuit for a short to voltage.
  6. Ignition OFF, test for infinite resistance between the signal circuit terminal 2 at the K9 Body Control Module harness connector and ground.
    • If less than the specified range, test the signal circuit for a short to ground.
  7. Test for less than 1Ω between the signal circuit terminal 2 at the K9 Body Control Module harness connector and the signal circuit terminal 2 at the K64 Theft Deterrent Module harness connector.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  8. If all circuits test normal, replace the K64 Theft Deterrent Module.
  9. Ignition ON, verify DTC B3055 is not set as current.
    • If the DTC is set, replace the K9 Body Control Module.
