Diagnostic Test

WARNING:

1. TEST RELEASE SWITCH

With the scan tool in Inputs/Outputs, read the FLIP-UP GLASS REL SW state.

Observe the scan tool and move the tailgate handle from open to closed positions.

Does the scan tool display OPEN then CLOSED as the handle is moved?

Yes

- Go to 2

No

- Go to 5

2. CHECK FLIP-UP GLASS RELEASE MOTOR





Disconnect the Flip-Up Glass Release Motor connector.

Connect a 12-volt test light between the (P100) Flip-Up Glass Release Motor Driver circuit and the (Z213) Ground circuit in the motor connector.

With the scan tool actuate the RELEASE FLIP-UP GLASS.

Does the test light illuminate brightly when the motor is actuated?

Yes

- Replace the Flip-Up Glass Release Motor.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 3

3. CHECK FOR OPEN GROUND CIRCUIT





Using a 12-volt test light connected to 12-volts, check the (Z213) Ground circuit in the motor connector.

Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the (Z213) Ground circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

4. TEST FOR OPEN (P100) FLIP-UP GLASS RELEASE MOTOR DRIVER WIRE





Turn the ignition off.

Connect a jumper wire between the (P100) Flip-Up Glass Release Motor Driver circuit and (Z213) Ground in the motor connector.

Disconnect the Body Control Module C1 connector.

Measure the resistance between ground and the (P100) Flip-Up Glass Release Motor Driver circuit.

Is the resistance below 5.0 ohms?

Yes

- Replace the Body Control Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Repair the (P100) Flip-Up Glass Release Motor Driver circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

5. CHECK FLIP-UP GLASS RELEASE SWITCH





Remove the tailgate trim panel.

Disconnect the Flip-Up Glass Release Switch. connector.

Connect a jumper wire between the (P101) Flip-Up Glass Release Switch circuit and the (G910) Tailgate Switch Ground circuit in the switch connector.

With the scan tool in Data Display, read the Flip-Up Glass Rel Sw state.

Does the scan tool display CLOSED?

Yes

- Replace the Flip-Up Glass Release Switch.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 6

6. CHECK (G910) TAILGATE SWITCH GROUND FOR AN OPEN





Using a 12-volt test light connected to 12-volts, check the (G910) Tailgate Switch Ground circuit.

Does the test light illuminate brightly?

Yes

- Go To 7

No

- Repair the (G910) Tailgate Switch Ground circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

7. CHECK (P101) FLIP-UP GLASS RELEASE SWITCH SENSE WIRE FOR AN OPENl





Turn the ignition off.

Connect a jumper wire between the (P101) Flip-Up Glass Release Switch Sense circuit and (G910) Ground circuit in the Flip-Up Glass Release Switch connector.

Disconnect the Body Control Module C1 connector.

Measure the resistance between ground and the (P101) Flip-Up Glass Release Switch Sense circuit.

Is the resistance below 5.0 ohms?

Yes

- Replace the Body Control Module.

No

- Repair the (P101) Flip-Up Glass Release Switch Sense circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
