Pinpoint Test P: The Luggage Compartment Lid Is Inoperative - With Police Package

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Luggage Compartment for schematic and connector information.

Normal Operation 

Vehicles equipped with the police package have 2 luggage compartment release switches, 1 located on the instrument panel and 1 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 only when the key is in the ON position, the key is in the OFF position and the doors have not been opened, or the key is in the OFF position and the accessory delay relay has not timed out. If the switch receives voltage through circuit 517 (BK/WH), the switch receives voltage directly from the battery junction box (BJB) and is active at all times. When the luggage compartment 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 release solenoid is grounded through circuit 57 (BK).

This pinpoint test is intended to diagnose the following:

• Fuse
• Wiring, terminals or connectors
• Luggage compartment lid release switch
• Luggage compartment latch

PINPOINT TEST P: THE LUGGAGE COMPARTMENT LID IS INOPERATIVE - WITH POLICE PACKAGE 

1. P1 CHECK THE LUGGAGE COMPARTMENT LID RELEASE SWITCH FOR CORRECT OPERATION 
   • Disconnect: Luggage Compartment Release Switch C534
   • Disconnect: Luggage Compartment Release Switch C2203 or C2204

   • Measure the resistance between the suspect luggage compartment lid release switch pin 1, component side and suspect luggage compartment lid release switch pin 2, component side while pressing and releasing the luggage compartment lid release switch.
   • Is the resistance greater than 10,000 ohms with the luggage compartment lid release switch released, and less than 5 ohms with the luggage compartment lid release switch pressed? 
   1. YES  : Go to  P2.
   2. NO  : INSTALL a new luggage compartment lid release switch. TEST the system for normal operation.
2. P2 CHECK CIRCUITS 193 (YE/LG) AND 517 (BK/WH) FOR VOLTAGE 
   • Key in ON position.
   • Measure the voltage between the luggage compartment lid release switch(es), harness side and ground as follows:

     Circuit	Connector-Pin
     193 (YE/LG)	C534-1
     517 (BK/WH)	C2203-2
     193 (YE/LG)	C2204-2

   • Are the voltages greater than 10 volts? 
   1. YES  : Go to  P3.
   2. NO  : If the voltage is less than 10 volts on circuit 193 (YE/LG), CHECK that other components on the accessory delay system operate correctly. If the accessory delay system is OK, REPAIR circuit 193 (YE/LG). TEST the system for normal operation.

      If the voltage on circuit 517 (BK/WH) is less than 10 volts, VERIFY the BJB fuse 601 (20A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.

3. P3 CHECK CIRCUIT 84 (VT/YE) FOR AN OPEN 
   • Disconnect: Luggage Compartment Lid Release Solenoid C430
   • Measure the resistance between the suspect luggage compartment release switch connector, circuit 84 (VT/YE), harness side and the luggage compartment latch connector, circuit 84 (VT/YE), harness side as follows:

     Luggage Compartment Release Switch Connector-Pin	Luggage Compartment Latch Connector-Pin
     C430-2	534-2
     C430-2	C2203-1
     C430-2	C2204-1

   • Are the resistances less than 5 ohms? 
   1. YES  : Go to  P4.
   2. NO  : REPAIR the circuit. TEST the system for normal operation.
4. P4 CHECK CIRCUIT 57 (BK) FOR AN OPEN 
   Fig 2: Checking Circuit For Open

   • 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? 
   1. YES  : INSTALL a new luggage compartment lid latch. REFER to Luggage Compartment Lid Latch . TEST the system for normal operation.
   2. NO  : REPAIR the circuit. TEST the system for normal operation.
