9917 - TRUNK LATCH UNLOCKED SIGNAL CIRCUIT OPEN





- When Monitored: Continuously, with the ignition on.
- Set Condition: When the Power Top Control Module (PTCM) senses the Trunk Latch Locked signal is not active and the control module senses B(+) on the Trunk Latch Unlocked circuit.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

1. Read DTCs
Turn the ignition on.
With the DRBIII(R), read Current DTCs.
Are both Trunk Latch Signal Circuit Open DTCs set?

Yes

- Check the Trunk Latch Assembly ground circuit for a loose, damaged or corroded ground circuit. If the ground circuit is OK, replace the Trunk Latch Assembly.
- Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test

No

- Go To 2

2. Trunk Latch Assembly
Turn the ignition off.
Disconnect the Trunk Latch Assembly C1 harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Connect a fused jumper wire between the Trunk Latch Unlocked Signal circuit and the Trunk Latch Assembly Ground circuit of the Trunk Latch Assembly C1 harness connector.
Turn the ignition on.
With DRBIII(R), select Input/Output Display and monitor the TRUNK LTCH UNLCK SW.
Does the DRBIII(R) display TRUNK LTCH UNLCK SW "ACTIVE"?

Yes

- Replace the Trunk Latch Assembly.
- Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test

No

- Go To 3

3. Open Trunk Latch Unlocked circuit




Turn the ignition off.
Disconnect the Power Top Control Module C1 harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance of the Trunk Latch Unlocked signal circuit from the Trunk Latch Assembly C1 harness connector to the Power Top Control Module C1 harness connector.
Is the resistance below 5.0 ohms?

Yes

- Replace the Power Top Control Module.Removal.
- Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test

No

- Repair the Trunk Latch Unlocked circuit for an open.
- Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test
