Electronic Control Modules - Service Information: Diagnosis Dodge Durango III

DIAGNOSIS AND TESTING

The hard wired circuits between components related to the electronic front door control modules (also known as a Driver Door Module/DDM, a Passenger Door Module/PDM or Front Door Multiplex/MUX Modules) may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the front door control modules or the electronic controls and communication between modules and other devices that provide some features of the door modules. The most reliable, efficient, and accurate means to diagnose the front door control modules or the electronic controls and communication related to module operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

START-UP DIAGNOSTICS

When the DTCM is activated, the internal circuitry will undergo a diagnostic procedure. The controller will examine all inputs and outputs for short circuits to ground, short circuits to battery and open circuits and will also verify proper CPU and memory operation. If a fault is detected, a message will be sent out over the CAN C bus to the Cluster based Electronic Vehicle Information Center EVIC indicating that service is recommended.

After passing all diagnostic tests, the controller will receive and process inputs and produce the appropriate outputs. Proper monitoring of the controller inputs and outputs performance will continue.

The most reliable, efficient, and accurate means to diagnose the power liftgate system, the PLGM or the electronic controls and communication related to power liftgate or PLGM operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

The hard wired circuits between components related to the Steering Column Control Module (SCCM) and the Steering Control Module (SCM) may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the SCCM, the SCM or the electronic controls and communication between modules and other devices that provide some features of the SCCM or SCM. The most reliable, efficient, and accurate means to diagnose the SCCM, the SCM or the electronic controls and communication related to SCCM or SCM operation requires the use of a diagnostic scan tool.
