Body Control Modules: Other Dodge Durango I

AIR BAG CONTROL MODULE (ACM)

Air Bag Control Module (ACM) continuously monitors air bag system for faults to ensure driver-side and/or passenger-side air bag deployment will occur when necessary. There are no external impact sensors, it is all contained within ACM. Other components of air bag system include AIRBAG warning light, driver-side air bag module, clockspring, passenger-side air bag module, passenger-side air bag on/off switch and related wiring. When vehicle is started, AIRBAG warning light should illuminate for 6-8 seconds, then turn off. If AIRBAG warning light remains illuminated, a fault is indicated in air bag control system or CCD bus network between all body control modules. ACM has its own set of Diagnostic Trouble Codes (DTC). ACM DTC are not permanent and can clear when reason for code is corrected. When AIRBAG warning light is illuminated, see appropriate AIR BAG RESTRAINT SYSTEMS article.

CENTRAL TIMER MODULE (CTM)

On base-line models, CTM is hard wired to switches or indicators for chime and warning buzzer operations only, and does not communicate with any other modules through CCD bus. If a fault is present, repair switch and/or wiring or replace CTM as necessary.

On high-line models, Central Timer Module (CTM) is the main Body Control Module (BCM) for vehicle. CTM communicates with other modules through CCD bus and controls chime and warning indicators, courtesy entry lighting, Power Door Locks (PDL), Remote Keyless Entry (RKE), speed sensitive and intermittent wiper/washers and vehicle anti-theft monitoring related functions. CTM is fully addressible with DRBIII(R) scan tool, and is the preferred method for diagnostics. Retrieving CTM reports, Diagnostic Trouble Codes (DTC), or monitor actuator inputs and activate output commands can all be done using DRBIII(R), or compatible generic scan tool. During self-diagnostics or testing, if actuators and inputs can be monitored, and outputs are cycled when commanded, the fault is usually within the CTM.

CCD BUS SYSTEM

The Chrysler Collision Detection (CCD) bus is a pair of twisted wires traveling from module-to-module to receive and deliver coded information between modules. The code identifies information message and its importance. Codes are sent to all modules, and are addressed to appropriate module for which information is intended. When multiple messages attempt to gain access to CCD bus at once, codes are assigned by address, level of importance and priority ranking. The 2 twisted wires used by CCD bus system are called bus (+) positive and bus (-) (negative). Both wires carry approximately 1.8-2.8 volts. CCD bus network consists of some modules with "bias" and some modules with "termination".

"Bias" is the voltage divider of CTM network, and places both CCD bus (+) and CCD bus (-) circuits at 1.8-2.8 volts. "Termination" is the part of circuitry required to complete the voltage loop in CCD bus circuit and also provides some electromagnetic protection for CCD bus network. Termination in most all CCD bus system applications have a 120-ohm resistor connecting the CCD bus (+) and CCD bus (-) circuits, thus completing the CCD bus circuit. If a fault exists in CCD bus network, it must be corrected before proceeding with any other testing or diagnostics. For CCD bus diagnostic and testing procedures, see SYMPTOM INDEX DIRECTORY under SYSTEM TESTS.

COMPASS MINI TRIP COMPUTER (CMTC)

The Compass Mini Trip Computer (CMTC) is located in overhead console or Overhead Travel Information System (OTIS). This dual-function display provides a digital readout of ambient (outside) temperature and 8 primary compass readings to indicate direction in which vehicle is facing. CMTC is self-calibrated and requires no adjustment. The word CAL will be displayed to indicate that compass is in fast calibrating mode. The CAL display will be turned off after vehicle has completed 3 continuous circles without stopping, in an area free of magnetic disturbance, and calibration of compass is complete. If module displays ambient temperature while compass display is blank, vehicle must be demagnetized. If compass display still goes blank after vehicle is demagnetized, Compass Mini Trip Computer (CMTC) module must be replaced.

The Overhead Travel Information System (OTIS) provides vehicle operator with supplementary information on a Vacuum Fluorescent Display (VFD) in the overhead console (if equipped), and is controlled by the Compass Mini Trip Computer (CMTC). Vehicle operator selects and resets display functions through use of US/M, STEP, C/T and RESET buttons. OTIS obtains most of its information from the network through CCD bus.

OTIS powers up when it senses vehicle (battery) voltage through ignition input circuit. When OTIS is powered-up, the VFD display is blank, then becomes illuminated by segments of VFD. During this time, OTIS sends and receives information from CCD bus to determine what to display after initialization. OTIS will display dashes (- -) for any screens for which it did not receive CCD bus messages during initialization. Dashes will be replaced by valid information if and when it is received.

MECHANICAL INSTRUMENT CLUSTER (MIC)

With several different Mechanical Instrument Cluster (MIC) packages available, typical high-line model MICs include, but are not limited to, a speedometer, tachometer, fuel gauge, oil pressure gauge, water temperature gauge, voltmeter, an information Vacuum Fluorescent Display (VFD) and a series of warning lights (if equipped).

Powertrain Control Module (PCM) sends signals necessary for MIC to position gauges. MIC receives continuously updated messages through CCD bus and translates them to gauge positions. Central Timer Module (CTM) sends necessary signals for all indicator lights and dimming level settings to MIC through CCD bus, when ignition switch is in ON or START positions. Malfunction (CHECK ENGINE) indicator light state is sent to CTM from PCM through CCD bus. VFD odometer/trip display works when ignition switch is in ON or START positions from CTM, which also stores actual mileage information that odometer displays. If CCD bus network is transmitting data, odometer will display dashes (- -) instead of mileage reading. All other MIC features only work when ignition switch is in ON position.

VEHICLE THEFT SECURITY SYSTEM (VTSS)

Anti-theft control system, or Vehicle Theft Security System (VTSS), monitors vehicle doors, hood, trunk key cylinder and ignition for unauthorized operation/entry. When alarm is triggered, horn will sound for up to 3 minutes and parking lights will flash for 15-18 minutes. When an unauthorized entry into vehicle occurs, VTSS module signals Powertrain Control Module (PCM) through CCD bus to disable the ignition system. PCM then "zeros out" pulse width of fuel injectors, thus preventing engine from starting (start/stall condition). The vehicle will remain disabled until VTSS is disarmed.

To verify if VTSS is operational, perform the following procedure. Open driver's door (all others closed). Remove ignition key. Lock doors with interior Power Door Lock (PDL) switch. Close driver's door. If VTSS SET light flashes, system is armed and operational. If VTSS SET light does not flash, 20 engine cranking cycles have not occurred or there is a problem with VTSS system. VTSS will not arm if doors are locked using keys or manually locked from door knob. If horn will sound 3 times when either front door is unlocked, indicating alarm was activated.

CCD BUS FAILURE MESSAGES

If a CCD bus fault message is present, it must be repaired before proceeding with any other repair procedures. If CCD bus messages are stored, go to appropriate procedure for displayed fault message. See RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC) and SYMPTOM INDEX DIRECTORY tables.

SYSTEM TESTS

Note. A scan tool with 2000 diagnostic program cartridge, body diagnostics cable, oil pressure gauge, jumper wires, and DVOM will be needed for system tests. To access Diagnostic Trouble Codes (DTC), proceed to RETRIEVING DIAGNOSTIC TROUBLE CODES (DTC) under SELF-DIAGNOSTIC SYSTEM.
