The most common failure is a circuit fault which causes the loss of power or ground to the door control module e. Check all fuses that power up the DCM-E module on this vehicle. Check all grounds for the DCM-E. Locate where the ground attaching points are on the vehicle and make sure that these connections are clean and tight. If you must, take them off, get a small wire bristle brush and baking soda/water solution and clean each one, both the connector and where it connects. If any repairs were made, clear the diagnostic trouble codes from all the modules that set the code in memory, and see if you can now communicate with the DCM-E module. If communication is re-established with the DCM-E, then the fuses/connections were most likely your problem. If the code returns or communication still cannot be established with the module, locate the CAN bus communication connections on your vehicle, most importantly the DCM-E connector, which is usually located behind the kick panel adjacent to the door in question. may also be mounted inside the door in question. Disconnect the negative battery cable before unplugging the connector at the DCM-E. Once located, visually inspect the connectors and wiring. Look for scraping, rubbing, bare wires, burn spots or melted plastic. Pull the connectors apart and carefully inspect the terminals (the metal parts) inside the connectors. See if they look burned or have a green tint indicating corrosion. Use electrical contact cleaner and a plastic bristle brush if cleaning of the terminals is needed. Let dry and apply electrical grease where the terminals contact. Before connecting the connectors back to the DCM-E, make these few voltage checks. You will need to have access to a digital volt-ohmmeter (DVOM). Verify that you have power and ground at the DCM-E. Gain access to a wiring diagram and determine where the main powers and grounds come into the DCM-E. Reconnect the battery before continuing, with the DCM-E still disconnected. Connect the red lead of your voltmeter to each B+ (battery voltage) supply coming into the DCM-E connector and the black lead of your voltmeter to a good ground (if not sure, battery negative always works). You should see a reading of battery voltage. Verify that you have good grounds as well. Hook the red lead of your voltmeter to battery positive (B+) and the black lead to each ground circuit. Once again you should see battery voltage at each connection. If not, repair the power or ground circuit problem. Next, check the two communication circuits. Locate the CAN C+ (or HSCAN + circuit) and CAN C- (or HSCAN - circuit). With the black lead of your voltmeter connected to a good ground, connect the red lead to CAN C+. With the Key On, Engine Off, you should see about 2.6 volts and fluctuating slightly. Next, connect the red voltmeter lead to the CAN C- circuit. You should see approximately 2.4 volts and fluctuating slightly. Other manufacturers show CAN C- at approximately .5 volts and fluctuating Key On Engine Off. Check the specifications for your manufacturer. If all tests have passed and communication is still not possible, or you were unable to clear the U0203 fault code, the only thing left that can be done is to seek assistance from a trained automotive diagnostician, as this would indicate a failed DCM-E. Most of these DCM-E must be programmed, or calibrated to the vehicle to be installed correctly.
