Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent any electrical shorts or shocks.
Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Remove the ABS Module

Locate the ABS module, typically mounted on or near the brake master cylinder.
Use a socket set to remove the bolts holding the ABS module in place.
Carefully detach the wiring harness connected to the ABS module by pressing the release tab and pulling it out.
Remove the module from its mounting location.

3. Inspect and Replace

Inspect the old ABS module for signs of internal damage or water ingress.
If the module is faulty, replace it with a new unit, ensuring it is compatible with the 2019 Ram 1500 DT.
If reusing the module, clean any corrosion from the connectors and wiring.

4. Install the New ABS Module

Position the new or refurbished ABS module into place, ensuring it aligns correctly with the mounting points.
Reattach the wiring harness firmly until it clicks into place.
Secure the module with the mounting bolts, tightening them to the manufacturer’s specified torque (typically around 10-15 ft-lbs).

5. Reconnect Battery and Test

Reconnect the battery terminals, ensuring they are tight and secure.
Start the vehicle and check for any warning lights on the dashboard.
Perform a brake system test to ensure the ABS system is functioning correctly.
