Diagnostic Test

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. 1)  INTERMITTENT DTC 

    With the scan tool, erase the current Intrusion Transceiver Module DTC's.

    Turn the ignition off.

    Arm the VTSS and wait 1 minute.

    Disarm the VTSS and turn the ignition on.

    Does the scan tool display the same DTC? 

    Yes 

    1. Go To  2).

    No 

    1. The condition that caused this symptom is currently not present. Inspect the related wiring harness for a possible intermittent condition. Look for any chafed, pierced, pinched or partially broken wires.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
  2. 2)  (A117) FUSED B(+) (I.O.D.) CIRCUIT OPEN

    Gain access to the VTSS Siren.

    Disconnect the Siren connector.

    Using a 12-volt test light connected to ground, check the (A117) Fused B(+) (I.O.D.) circuit in the Siren connector.

    Does the test light illuminate brightly?  

    Yes 

    1. Go To  3).

    No 

    1. Repair the (A117) Fused B(+) (I.O.D.) circuit for an open.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
  3. 3)  (Z904) GROUND CIRCUIT 
    Fig 2: Checking Ground Circuit

    Using a 12-volt test light connected to 12-volts, check the (Z904) Ground circuit at the siren connector.

    Does the test light illuminate brightly? 

    Yes 

    1. Go To  4).

    No 

    1. Repair the (Z904) Ground circuit for an open.
    2. Perform BODY VERIFICATION TEST - 1A. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
  4. 4)  FAULTY SIREN 
    Fig 3: Connect Scope Input Cable To Siren Connector

    Use the DRBIII® and set up as follows:

    Use the Scope input cable CH7058, Cable to Probe adapter CH7062, and the red and black test probes.

    Connect the scope input cable to the channel one connector on the DRBIII®. Attach the red and black leads and the cable to probe adapter to the scope input cable.

    Select DRBIII® Stand-alone.

    Select lab scope.

    Select Live.

    Select 12 volt square wave.

    Press F2 for Scope.

    Press F2 and use the down arrow to set voltage range to 20 volts. Press F2 again when complete.

    Disconnect the Siren connector.

    Connect the black lead to the chassis ground. Connect the red lead to the (D96) Siren Signal Control circuit in the Siren connector.

    Close all doors and arm the VTSS.

    Observe the voltage displayed on the DRBIII® Lab Scope.

    Is there a voltage square wave present 1 to 2 seconds? 

    Yes 

    1. Connect a known good siren and try to reset the DTC. If the DTC does not reset the original siren needs to be replaced. If the DTC does reset replace the ITM.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

    No 

    1. Go To  5).
  5. 5)  (D96) SIREN SIGNAL CONTROL CIRCUIT SHORT TO BATTERY 
    Fig 4: Measuring Voltage Of Siren Signal Control Circuit
    GC0040897Courtesy of DAIMLERCHRYSLER CORP.

    Disconnect the Siren harness connector.

    Measure the voltage of the (D96) Siren Signal Control circuit.

    Is there any voltage present?  

    Yes 

    1. Repair the (D96) Siren Signal Control circuit for a short to voltage.

      Perform BODY VERIFICATION TEST - 1A. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

    No 

    1. Go To  6).
  6. 6)  (D96) SIREN SIGNAL CONTROL CIRCUIT SHORT TO GROUND 
    Fig 5: Measuring Resistance Between Ground & Siren Signal Control Circuit
    GC0040898Courtesy of DAIMLERCHRYSLER CORP.

    Disconnect the Siren harness connector.

    Disconnect the Intrusion Transceiver Module harness connector.

    Measure the resistance between ground and the (D96) Siren Signal Control circuit.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Go To  7).

    No 

    1. Repair the (D96) Siren Signal Control circuit for a short to ground.
    2. Perform BODY VERIFICATION TEST - 1A. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
  7. 7)  (D96) SIREN SIGNAL CONTROL CIRCUIT OPEN 
    Fig 6: Measuring Resistance Of Siren Signal Control Circuit
    GC0040899Courtesy of DAIMLERCHRYSLER CORP.

    Disconnect the Intrusion Transceiver Module harness connector.

    Measure the resistance of the (D96) Siren Signal Control circuit between the Intrusion Transceiver Module and the Siren connector.

    Is the resistance below 5.0 ohms? 

    Yes 

    1. Replace the Intrusion Transceiver Module in accordance with the Service Information.
    2. Perform BODY VERIFICATION TEST - VER 1. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

    No 

    1. Repair the (D96) Siren Signal Control circuit for an open.
