Steps

🔧Does this apply to your car? After replacing an electric power steering module, most vehicles require a steering angle sensor calibration (and often module coding) with a capable scan tool. Skipping calibration can cause pull, lane-keep faults, or stability-control warnings.

✓Expert-verified. Personally reviewed and approved by OLP's master technicians (Chris Hackleman & Jeff Moore — 20+ years each). Always follow the vehicle's factory service information and torque specs.

This procedure covers the removal and replacement of the electric power steering control module on a 2014-2018 Chevrolet Silverado 1500 with the 5.3L V8 engine.

Warnings

⚠Disconnecting the battery will erase radio presets and may require relearning procedures for other modules.

⚠Do not turn the steering wheel with the intermediate shaft disconnected, as this can damage the clockspring.

ℹ️The electric power steering module is located on the steering column below the instrument panel.

Preparation

Park vehicle on level ground and set parking brake
Turn ignition to OFF position and remove key
Disconnect negative battery cable and wait 2 minutes for airbag system capacitors to discharge
Adjust steering wheel to full up position for best access
Remove driver's side lower dash panel/knee bolster using trim tools

Procedure

1
Disconnect Intermediate Steering Shaft
Locate the intermediate shaft coupling bolt at the base of the steering column. Mark the relationship between the upper and lower shafts with a paint pen or marker for proper alignment during reinstallation. Remove the coupling bolt and separate the intermediate shaft from the steering column shaft.
2
Remove Steering Column Covers
Remove the upper and lower steering column cover screws. There are typically 4-6 screws holding the covers in place. Carefully separate the covers and set aside.
3
Disconnect Electrical Connectors
Locate the EPS module electrical connector on the side of the steering column. Press the connector release tab and carefully pull the connector straight out from the module. Note the routing of the wiring harness for reinstallation.
4
Remove EPS Module Mounting Bolts
Identify the EPS module mounting bolts securing the module to the steering column bracket. There are typically 2-3 mounting bolts. Remove these bolts while supporting the module weight.
5
Remove EPS Module
Carefully slide the EPS module off the steering column shaft. The module may be tight on the shaft; gently wiggle and pull straight back to remove. Inspect the steering shaft for any damage or wear.
6
Install New EPS Module
Clean the steering shaft with a wire brush if needed. Align the new EPS module with the steering column shaft, ensuring the splines engage properly. Slide the module fully onto the shaft until it seats against the mounting bracket.
7
Install Module Mounting Bolts
Apply a small amount of medium-strength thread locker to the mounting bolt threads. Install the mounting bolts and tighten to specification in a cross pattern to ensure even seating.
8
Reconnect Electrical Connector
Route the wiring harness as noted during removal. Push the electrical connector firmly into the EPS module until you hear and feel a positive click. Verify the connector is fully seated and the locking tab is engaged.
9
Reinstall Steering Column Covers
Position the lower and upper steering column covers around the column. Install all cover screws and tighten to specification. Ensure covers are properly aligned and gaps are even.
10
Reconnect Intermediate Shaft
Align the marks made during disassembly on the intermediate shaft and steering column shaft. Ensure the shafts are fully engaged and aligned. Install the coupling bolt and tighten to specification.
⚠Ensure the intermediate shaft is properly aligned using the alignment marks. Misalignment can cause steering issues and premature wear.
11
Reinstall Lower Dash Panel
Position the driver's side lower dash panel/knee bolster and secure all fasteners. Ensure all clips are properly engaged.
12
Reconnect Battery and Initialize System
Reconnect the negative battery cable. Turn the ignition to ON position without starting the engine. The power steering warning light should illuminate briefly then turn off. If available, use a scan tool to clear any stored DTCs and verify EPS module communication.

Reassembly

Ensure all electrical connectors are fully seated and locked
Verify steering column covers are properly aligned and all screws are tight
Confirm intermediate shaft coupling bolt is torqued to specification

Verification

Turn steering wheel lock-to-lock with engine off to verify smooth operation with no binding
Start engine and verify power steering warning light turns off
With engine running, turn steering wheel to verify proper power assist in both directions
Test drive vehicle at low speed to confirm normal steering operation and no warning lights
Verify steering wheel returns to center properly after turns
Use scan tool to verify no EPS-related diagnostic trouble codes are present
