Pinpoint Test F: The Luggage Compartment Lid Release Is Inoperative/Does Not Operate Correctly - With Police Package
Refer to Wiring Diagram Set 113, Luggage Compartment for schematic and connector information. Diagrams By Number
Normal Operation
Vehicles equipped with the police package have 2 luggage compartment lid release switches, one located on the instrument panel and one located on the LH door trim panel. The instrument panel switch is supplied voltage through 1 of the 2 circuits, circuit 193 (YE/LG) or circuit 517 (BK/WH). If the switch receives voltage through circuit 193 (YE/LG), the switch receives voltage through the accessory delay relay and the switch is active any time the accessory delay relay is energized. If the switch receives voltage through circuit 517 (BK/WH), the switch receives voltage directly from the Battery Junction Box (BJB) circuit breaker 601 (20A) and is active at all times. When the luggage compartment lid release switch is pressed, the switch supplies voltage to circuit 84 (VT/YE ) sending voltage to the luggage compartment release solenoid releasing the luggage compartment lid. The luggage compartment lid release solenoid is grounded through circuit 57 (BK).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Luggage compartment lid release solenoid (part of the luggage compartment lid latch)
- Luggage compartment lid release switch
PINPOINT TEST F: THE LUGGAGE COMPARTMENT LID RELEASE IS INOPERATIVE/DOES NOT OPERATE CORRECTLY - WITH POLICE PACKAGE
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
F1 CHECK CIRCUIT 193 (YE/LG) OR 517 (BK/WH) FOR VOLTAGE
- Disconnect: Suspect Luggage Compartment Lid Release Switch.
- Ignition ON.
- Measure the voltage between the luggage compartment lid release switch, harness side and ground as follows:
- Is the voltage greater than 10 volts?
Yes
GO to F2.
No
REPAIR the circuit in question. TEST the system for normal operation.
-------------------------------------------------
F2 CHECK THE LUGGAGE COMPARTMENT LID RELEASE SWITCH FOR CORRECT OPERATION
- NOTE: If the fuse in the jumper wire fails, repair circuit 84 (VT/YE) for a short to ground.
- Connect a fused jumper wire between the luggage compartment lid release switch terminals, harness side as follows:
- Does the luggage compartment lid release?
Yes
INSTALL a new luggage compartment lid release switch. TEST the system for normal operation.
No
LEAVE the jumper wire connected. GO to F3.
-------------------------------------------------
F3 CHECK CIRCUIT 84 (VT/YE) FOR VOLTAGE
- Disconnect: Luggage Compartment Lid Release Solenoid C430.
- Measure the voltage between the luggage compartment lid latch C430-2, circuit 84 (VT/YE), harness side and ground.
- Is the voltage greater than 10 volts?
Yes
GO to F4.
No
REPAIR the circuit for an open. TEST the system for normal operation.
-------------------------------------------------
F4 CHECK CIRCUIT 57 (BK) FOR AN OPEN
- Disconnect: Negative Battery Cable.
- Measure the resistance between the luggage compartment lid release solenoid C430-3, circuit 57 (BK), harness side and ground.
- Is the resistance less than 5 ohms?
Yes
INSTALL a new luggage compartment lid latch. REFER to Luggage Compartment Lid Latch Service and Repair. TEST the system for normal operation.
No
REPAIR the circuit. TEST the system for normal operation.
