How to Service and Repair the Engine Control Module (ECM) for a 6.7L Diesel on Dodge Ram 3500?

For the 6.7L Diesel ECM, put it in the ECM support bracket, secure it using the bolts and tighten those bolts to 24 Nm (18 ft. lbs.). Look for corrosion, damage or dirt in the pins inside the electrical connectors and check that they are not bent; repair any weak, filthy, bent or corroded ones, as they may result in poor conductivity and can create both intermittent electrical problems and Diagnostic Trouble Codes (DTCs). Clean all the pins in the electrical connectors with an electrical contact cleaner, then bolt the connectors onto the ECM, making sure the tightness is 3 Nm (27 in. lbs.). After that, mount the splash shield and the left front wheel and hook up both negative battery cables. Use the scanner to clear any error code messages from the ECM. For each fuel injector, a unique six-digit alphanumeric correction code-printed on the intake side-lets you know the injector calibration. Whenever fuel injectors are swapped, make sure to enter the code in the ECM and should you replace the ECM, transfer the injector codes from the old injectors to the new ECM with a scan tool.

How to Replace an Engine Control Module (ECM) on Dodge Ram 3500?

Bolted to the engine and placed behind the fuel filter is the Engine Control Module. Begin with checking the Diagnostic Trouble Codes (DTC's) from the Powertrain Control Module (PCM) or ECM. To save your insulation from a voltage spike, unplug the ECM connectors only after turning off the ignition and removing the negative terminals of your battery. Once you've removed the 50-way electrical connector bolt at the ECM using a ball-hex bit or similar, remove the connector as you take off the bolt. After that, get rid of the three ECM mounting bolts and take the ECM out of the car. As paint on the back of the ECM may harm the ground, make sure to avoid painting it. Wipe the ECM attaching areas on the engine block, set the ECM and put in the three bolts while tightening them to 24 Nm (18 ft. lbs.). Examine both the ECM pins and the pins in the 50-way electrical connector for corrosion or damage and if you find anything, have it repaired. Also, spray a suitable dry cleaner on the 50-way connectors' pins to clean them. Connect the 50-way plug to the ECM and install the connector hex bolt by tightening it. Place the new battery cables and again turn the key to the ON setting. To set up the sensor, depress the pedal slowly without cranking and then let it go while the ECM reads the data so that no DTCs appear. Then, follow DRB scan tool instructions to remove all the stored companion DTC's from the PCM.

Q: How to Service and Repair the Engine Control Module (ECM) for a 6.7L Diesel on Dodge Ram 3500?
A:
For the 6.7L Diesel ECM, put it in the ECM support bracket, secure it using the bolts and tighten those bolts to 24 Nm (18 ft. lbs.). Look for corrosion, damage or dirt in the pins inside the electrical connectors and check that they are not bent; repair any weak, filthy, bent or corroded ones, as they may result in poor conductivity and can create both intermittent electrical problems and Diagnostic Trouble Codes (DTCs). Clean all the pins in the electrical connectors with an electrical contact cleaner, then bolt the connectors onto the ECM, making sure the tightness is 3 Nm (27 in. lbs.). After that, mount the splash shield and the left front wheel and hook up both negative battery cables. Use the scanner to clear any error code messages from the ECM. For each Fuel Injector, a unique six-digit alphanumeric correction code-printed on the intake side-lets you know the injector calibration. Whenever fuel injectors are swapped, make sure to enter the code in the ECM and should you replace the ECM, transfer the injector codes from the old injectors to the new ECM with a scan tool.

Q: How to Replace an Engine Control Module (ECM) on Dodge Ram 3500?
A:
Bolted to the engine and placed behind the Fuel Filter is the Engine Control Module. Begin with checking the Diagnostic Trouble Codes (DTC's) from the Powertrain Control Module (PCM) or ECM. To save your insulation from a voltage spike, unplug the ECM connectors only after turning off the ignition and removing the negative terminals of your battery. Once you've removed the 50-way electrical connector bolt at the ECM using a ball-hex bit or similar, remove the connector as you take off the bolt. After that, get rid of the three ECM mounting bolts and take the ECM out of the car. As paint on the back of the ECM may harm the ground, make sure to avoid painting it. Wipe the ECM attaching areas on the engine block, set the ECM and put in the three bolts while tightening them to 24 Nm (18 ft. lbs.). Examine both the ECM pins and the pins in the 50-way electrical connector for corrosion or damage and if you find anything, have it repaired. Also, spray a suitable dry cleaner on the 50-way connectors' pins to clean them. Connect the 50-way plug to the ECM and install the connector hex bolt by tightening it. Place the new battery cables and again turn the key to the ON setting. To set up the sensor, depress the pedal slowly without cranking and then let it go while the ECM reads the data so that no DTCs appear. Then, follow DRB scan tool instructions to remove all the stored companion DTC's from the PCM.
