Diagnostic Test

1. FLIP-UP GLASS AJAR FUNCTIONAL TEST

Open the Flip-up Glass.
With the scan tool in Data Display, read the FLIP-UP AJAR SW state.

Does the scan tool display TRUE?

Yes


No

2. OPEN FLIP-UP GLASS AJAR SWITCH GROUND CIRCUIT



Disconnect the Tailgate Flip-up Glass Ajar switch connector.
Using a 12-volt Test Light connected to 12-volts, test the Ground circuit.

Does the test light illuminate brightly?

Yes


No

3. CHECK FOR OPEN FLIP-UP GLASS AJAR SWITCH



With the scan tool in Data Display, read the FLIP-UP AJAR SW state.
Connect a jumper wire between Sense circuit and the Ground circuit in the Tailgate Flip-Up Glass Ajar Switch connector.

Does the scan tool display FLIP-UP AJAR SW: TRUE?
