Initial Inspection and Diagnostic Overview
VEHICLE THEFT SECURITY SYSTEMThe VTSS-related hard wired inputs to and outputs from the high-line or premium Central Timer Module (CTM) may be diagnosed and tested using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM, the Powertrain Control Module (PCM), or the Chrysler Collision Detection (CCD) data bus network. In order to obtain conclusive testing of the VTSS, the CTM, the PCM, and the CCD data bus network must also be checked.
The most reliable, efficient, and accurate means to diagnose the VTSS requires the use of a DRBIII scan tool. Refer to the appropriate diagnostic information. The DRBIII scan tool can provide confirmation that the CCD data bus network is functional, that all of the electronic modules are sending and receiving the proper messages over the CCD data bus, and that these modules are receiving the proper hard wired inputs and responding with the proper hard wired outputs needed to perform their functions. See the "Vehicle Theft Security System" menu item on the DRB III scan tool.
System Diagnostics
* Fault detection is through active and stored Diagnostic Trouble Codes (DTC's)
* DTC's are displayed by the DRB III (R).
* Active DTC's are those which currently exist in the system.
* The condition causing the fault must be repaired in order to clear this type of DTC.
* Stored DTC's are those which occurred in the system since the A/C-Heater Control Module received the last "clear diagnostic info" message.
System Controls
* is fully addressable with the DRB III (R).
* Refer to these systems for the trouble code / symptom diagnostic procedures.
