REMOVAL

To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery cable must be disconnected before unplugging PCM connectors.

  1. Disconnect negative battery cable at battery.
  2. Remove cover over electrical connectors. Cover snaps onto PCM.
  3. Carefully unplug the three 32 - way connectors from PCM.
  4. Remove three PCM mounting bolts and remove PCM from vehicle.

INSTALLATION

  1. Install PCM and mounting bolts to vehicle.
  2. Tighten bolts to 3 - 5 N·m (30 - 40 in. lbs.)
  3. Check pin connectors in the PCM and the three 32 - way connectors for corrosion or damage. Repair as necessary.
  4. Install three 32 - way connectors.
  5. Install cover over electrical connectors. Cover snaps onto PCM.
  6. Install battery cable.
  7. Use the DRB scan tool to reprogram new PCM with vehicles original Identification Number (VIN) and original vehicle mileage. If this step is not done, a Diagnostic Trouble Code (DTC) may be set.



Make sure wherever you buy the new one from that you provide your Durango's VIN code and mileage so that they can program it for you. If not programmed, the vehicle will not start. Also, used units from salvage yards cannot be reprogrammed so you cannot used a salvage yard one.

where can i get a DRB scan tool
Hi,

As long as you have the PCM programmed with your VIN code and mileage prior to installing it, you dont need to the DRB scan tool.

Almost every parts store you order it from will request your VIN code and mileage so that it is programmed by the supplier before the ship it out to you or your parts store.

IF you buy one unprogrammed, then you will need to run it by the dealer to be programmed. Usual charge is 1 hour labor, which is cheaper than buying a DRB scan tool. They run from $5000 to $8000

Again, just make sure to supply your VIN code and mileage and order it to come programmed already and you will not need to the scan tool. Already programmed, it is just plug in and go.
