Electronic Control Modules - Service Information: Diagnosis Dodge Durango II рестайлинг

SYSTEM SELF-TEST

When the ignition switch is turned-on the microprocessor is tested. If an error occurs during the test, a DTC will be set into the memory. However it is possible the DTC will not be stored in memory if the error has occurred in the module were the DTC's are stored.

The ABM contains a self check program that illuminates the ABS and ESP warning lights when a ABS system fault is detected. If only the ESP light is illuminated ESP system fault is detected. Faults are stored in memory and are accessible with the scan tool.

System faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected.

Diagnostic Test

1. 1) Perform Body Verification Test Disconnect all jumper wires and reconnect all previously disconnected components and connectors. Ensure that all accessories are turned off. Ensure that the battery is fully charged. Turn the ignition on. With the scan tool, record and erase DTCs from all modules. If an electronic control module was replaced, select the applicable module from the scan tool menu and press "Misc. Functions". If the module has programmable features, program as necessary. If any repairs were made to the Power Liftgate, use the scan tool and perform the open and close system tests. Observe the instructions on the scan tool. For MTC systems only, if repairs were made to any of the HVAC door actuator circuits, with the scan tool in HVAC, select System Tests and then select Actuator DTC Detection. The test must pass before proceeding to the next step. For either ATC or MTC systems, if repairs were made to any of the HVAC doors, linkage, door actuators, or door actuator circuits, with the scan tool in HVAC, select System Tests and then select Actuator Calibration Test. The test must pass before proceeding to the next step. Turn the ignition off, wait 10 seconds, and then turn the ignition on. Operate all functions of the system that caused the original concern. With the scan tool, select ECU View. Check for DTCs in the modules. Are DTCs present in any of the modules or is the original condition still present? Yes The repair is not complete. Refer to the related category for the DTC or symptom that is still present. No The repair is complete.

There are two Memory Mirror Modules (these are sometimes referred to as Driver Door Modules (DDM) and Passenger Door Modules (PDM) within the memory system. One located in the driver door and one in the passenger door, just behind the door trim panel. The modules send a bus message to the power mirrors to adjust them to a preset position when a memory recall request has been made.

The memory mirror modules also act as an interface in each door for electrical functions (door lock switches and door ajar switches).

The Memory System makes available for immediate recall personalized preferences of the following

1. Automatic temperature control settings.
2. Outside mirror positions.
3. Power adjustable brake and accelerator pedal position.
4. Power seat horizontal, vertical, recliner, and easy entry positions.
5. Radio push button station selections.

The major components of the Memory System are

1. Memory Selector Switch - located in the driver door trim panel.
2. Driver Memory Mirror Module (DMMM) - located in the driver door, behind the trim panel.
3. Passenger Memory Mirror Module (PMMM) - located in the passenger door, behind the trim panel.
4. Sentry Key Remote Entry Module (SKREEM) - located at ignition key cylinder.
5. Remote Keyless Entry (RKE) Transmitter - located with ignition key.
6. Memory Seat Module (MSM) - located underneath the driver seat and also controls the Adjustable Pedals.
7. Radio - located in the instrument panel center stack.
8. Automatic Temperature Control (ATC) - located in the instrument panel center stack.

The memory recall is available at the press of a button on the drivers door trim panel or, by using the Remote Keyless Entry (RKE) transmitter if it is programmed to trigger the recall.

Radio settings include up to 20 push button presets (10 AM and 10 FM), and the last station selection, even if it is not one of the 20 preset selections.

REPAIR PROCEDURE - Using StarMOBILE® Standalone Diagnostic Mode

Note. StarMOBILE® Standalone Mode is an efficient way to flash ECUs without having direct access to a network connection. It involves first copying the flash file to the StarMOBILE® device which DOES require a network connection. Once the file has been copied to the StarMOBILE® device, it can be used in a Standalone mode to flash the ECU WITHOUT a network connection.

Note. StarMOBILE® does not need to be connected to a vehicle when retrieving a flash file for Standalone Mode.
