Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION

Turn the ignition on.
With the scan tool, record and erase DTC's

YES: Go To 2
NO: The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test




2. SWITCH SHORTED

With the scan tool, erase DTC's.
Disconnect the Decklid or Liftgate Release Switch connector.

YES: Go To 3




3. (P1) DECKLID OR (P30) LIFTGATE RELEASE SWITCH SENSE CIRCUIT SHORT TO GROUND

Turn the ignition off.
Disconnect the Cluster C3 connector.
Measure the resistance between ground and the (P1) Decklid or (P30) Liftgate Release Switch Sense circuit.

Q: Is the resistance below 10,000.0 ohms?

YES: Repair the (P1) Decklid or (P30) Liftgate Release Switch circuit for a short to ground. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
