Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION CHART Electrical Smart junction box (SJB) fuse(s): 9 (15A) 10 (15A) 25 (10A) Wiring, terminals or connectors Courtesy lamps Map lamps Puddle lamps Luggage compartment lamp Vanity lamps Overhead console Instrument panel dimmer switch (part of the headlamp switch) SJB
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
- If the scan tool does not communicate with the VCM: Check the VCM connection to the vehicle. Check the scan tool connection to the VCM. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-293472) article, No Power To The Scan Tool, to diagnose no communication with the scan tool.
- If the scan tool does not communicate with the vehicle: Verify the ignition key is in the ON position. Verify the scan tool operation with a known good vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-293472) article to diagnose no response from the PCM.
- Carry out the network test. If the scan tool responds with no communication with the SJB or liftgate/trunk module (LTM) (if equipped), refer to «MODULE COMMUNICATIONS NETWORK»(ref-293472) article. If the network test passes, retrieve and record the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the SJB and the LTM (if equipped).
- If the DTCs retrieved are related to the concern, refer to DTC Tables. For all other DTCs, refer to «MULTIFUNCTION ELECTRONIC MODULES»(ref-293473) article.
- If no DTCs related to the concern are retrieved, go to «Symptom Chart»(ref-293474-S00680275162008080700000) .

- K1 CHECK THE LUGGAGE COMPARTMENT LATCH Open the luggage compartment using the integrated keyhead transmitter (IKT) or the luggage compartment release switch on the instrument panel. Does the luggage compartment open? YES : Go to K2 . NO : REFER to «HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS»(ref-293464) article.
- K2 CHECK THE LUGGAGE COMPARTMENT AJAR PID Key in ON position. Enter the following diagnostic mode on the diagnostic tool: SJB DataLogger Monitor the SJB luggage compartment ajar switch PID (DECKLID) while opening and closing the luggage compartment. Does the luggage compartment ajar switch PID value agree with the luggage compartment positions? YES : Go to K5 . NO : Go to K3 .
- K3 CHECK THE LUGGAGE COMPARTMENT AJAR SWITCH Disconnect: Luggage Compartment Lid Latch C4223 Enter the following diagnostic mode on the diagnostic tool: SJB DataLogger Monitor the SJB luggage compartment ajar switch PID (DECKLID). Connect a (5A) jumper wire between the luggage compartment latch C4223-1, circuit CPL58 (GY/OG) harness side, and the luggage compartment latch C4223-4, circuit GD147 (BK/VT) harness side. Does the luggage compartment ajar switch PID indicate ajar with the jumper wire removed and closed with the jumper wire connected? YES : REMOVE the jumper wire. INSTALL a new luggage compartment lid latch. REFER to «HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS»(ref-293464) article. TEST the system for normal operation. NO : REMOVE the jumper wire. Go to K4 .
- K4 CHECK CIRCUIT CPL58 (GY/OG) FOR AN OPEN AND SHORT TO GROUND Key in OFF position. Disconnect: SJB C2280c Measure the resistance between the luggage compartment lid latch C4223-1, circuit CPL58 (GY/OG), harness side and the SJB C2280c-16, circuit CPL58 (GY/OG), harness side; and between the luggage compartment lid latch C4223-1, circuit CPL58 (GY/OG), harness side and ground. Is the resistance less than 5 ohms between the luggage compartment lid latch and the SJB, and greater than 10,000 ohms between the luggage compartment lid latch and ground? YES : Go to K8 . NO : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- K5 CHECK CIRCUIT CLN09 (YE/GN) FOR AN OPEN NOTE: Make sure all other demand lamps are operating before continuing this pinpoint test. Disconnect: Luggage Compartment Lamp C428 Key in ON position. Measure the voltage between the luggage compartment lamp C428-1, circuit CLN09 (YE/GN), harness side and ground. Is the voltage greater than 10 volts? YES : Go to K6 . NO : REPAIR the circuit. TEST the system for normal operation.
- K6 CHECK THE LUGGAGE COMPARTMENT LATCH Disconnect: Luggage Compartment Lid Latch C4223 Connect: Luggage Compartment Lamp C428 Monitor the luggage compartment lamp. Connect a (5A) jumper wire between the luggage compartment latch C4223-2, circuit CLN13 (WH/BU) harness side, and the luggage compartment latch C4223-4, circuit GD147 (BK/VT) harness side. Is the luggage compartment lamp illuminated with the jumper wire installed and off with it removed? YES : REMOVE the jumper wire. INSTALL a new luggage compartment lid latch. REFER to «HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS»(ref-293464) article. TEST the system for normal operation. NO : REMOVE the jumper wire. Go to K7 .
- K7 CHECK CIRCUIT CLN13 (WH/BU) FOR AN OPEN AND SHORT TO GROUND Key in OFF position. Disconnect: Luggage Compartment Lamp C428 Measure the resistance between the luggage compartment lid latch C4223-2, circuit CLN13 (WH/BU), harness side and the luggage compartment lamp C428-2, circuit CLN13 (WH/BU), harness side; and between the luggage compartment lid latch C4223-2, circuit CLN13 (WH/BU), harness side and ground. Is the resistance less than 5 ohms between the luggage compartment lid latch and the luggage compartment lamp, and greater than 10,000 ohms between the luggage compartment lid latch and ground? YES : INSTALL a new luggage compartment lamp. TEST the system for normal operation. NO : REPAIR the circuit. TEST the system for normal operation.
- K8 CHECK FOR CORRECT SJB OPERATION Disconnect all the SJB connectors. Check for: corrosion damaged pins pushed-out pins Connect all the SJB connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present? YES : INSTALL a new SJB. REFER to «MULTIFUNCTION ELECTRONIC MODULES»(ref-293473) article. TEST the system for normal operation. NO : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
Pinpoint Test L: The Battery Saver Does Not Deactivate After Time-Out
Refer to appropriate SYSTEM WIRING DIAGRAMS article, Interior lamps for schematic and connector information.
- L1 CHECK THE SJB IGNITION SWITCH PID Key in ON position. Enter the following diagnostic mode on the diagnostic tool: SJB DataLogger Monitor the SJB ignition switch PID (IGN_SW) while rotating the ignition switch through all positions. Does the ignition switch PID agree with the ignition switch positions? YES : Go to L2 . NO : REFER to «STEERING COLUMN SWITCHES»(ref-293477) article.
- L2 CHECK CIRCUIT CLN09 (YE/GN) FOR A SHORT TO VOLTAGE Key in OFF position. Disconnect: SJB C2280d Key in ON position. Operate the demand lamps. Do the demand lamps illuminate? YES : REPAIR the circuit. TEST the system for normal operation. NO : Go to L3 .
- L3 CHECK FOR CORRECT SJB OPERATION Disconnect all the SJB connectors. Check for: corrosion damaged pins pushed-out pins Connect all the SJB connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present? YES : INSTALL a new SJB. REFER to «MULTIFUNCTION ELECTRONIC MODULES»(ref-293473) article. TEST the system for normal operation. NO : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
