2025-2026 Silverado 1500 Steering Module: Failure Symptoms & Programming Guide

Symptoms of a Failing Steering Column Control Module

A problem with the Steering Column Control Module (SCCM) on a 2025-2026 Silverado can manifest in several ways, often affecting multiple, seemingly unrelated functions. Because the module controls so many different components, a single internal fault can cause a variety of issues.

• Malfunctioning Controls: The most common symptoms are erratic or non-functional controls mounted to the column. This includes turn signals that don't work, windshield wipers that won't turn on or off, or cruise control that cannot be set.
• Dead Steering Wheel Buttons: Audio volume, track selection, and phone control buttons on the steering wheel may stop responding intermittently or altogether.
• "Service Steering Column Lock" Message: A warning message may appear on the driver information center. This indicates the module has detected an internal fault or a communication problem.
• Starting Issues or No-Start Condition: The SCCM is often part of the vehicle's anti-theft and immobilizer system. A faulty module may fail to recognize a valid key, preventing the engine from starting.
• Warning Lights: A general Check Engine Light or a more specific power steering warning light may illuminate on the dashboard.

Common Diagnostic Trouble Codes (DTCs)

A professional scan tool that can read Body ("B") and Network ("U") codes is necessary for proper diagnosis. Common codes pointing to a faulty SCCM include:

• U0537: Invalid Data Received From Column Lock Module.
• B2515: Steering Column Lock Motor fault.
• B2910: A code that may specifically instruct to replace the Steering Column Lock Module.
• U0121, U0100, etc.: General communication codes indicating the SCCM is not communicating with other modules like the ABS or Engine Control Module.

Critical: Programming and Setup Required

Modern GM vehicles use a system called Techline Connect with the Service Programming System (SPS2). This process requires:

1. A subscription to GM's software service, which is typically purchased on a per-VIN basis.
2. A compatible J2534 Pass-Thru device (like a GM MDI 2) to connect the vehicle to a computer.
3. A stable, hardwired internet connection and a power supply to maintain steady battery voltage during programming.

This is a job for a GM dealership or a well-equipped independent repair shop. Do not attempt to install this module without having a plan for immediate, professional programming. After programming, additional setup procedures like steering angle sensor calibration may also be required.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

As of late 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) issued by GM or the NHTSA for the steering column control module on the 2025-2026 Chevrolet Silverado 1500. Recalls for these model years have focused on other areas, such as missing owner's manuals or issues with specific engine types.

Buying a Used Steering Column Control Module for Your 2025-2026 Silverado

A used OEM module from a recycled vehicle is a cost-effective and reliable alternative to a new part. Since these are original factory parts, they offer perfect fitment and function once programmed. However, careful purchasing is essential.

1. Verify Compatibility: Power Tilt vs. Manual Tilt

The single most important factor is matching the module to your truck's steering column options. GM uses different modules for columns with and without the power tilt and telescoping feature.

• For vehicles WITHOUT power tilt/telescoping, the common part number is 13543768.
• For vehicles WITH power tilt/telescoping, a common part number is 87834163.

These parts are not interchangeable. Always match the part number from your original module to the replacement part. If you are unsure, provide your VIN to the seller to confirm fitment.

2. Physical Inspection

When you receive the used part, inspect it carefully. Look for any signs of damage to the plastic housing, and pay close attention to the electrical connector pins. Ensure they are straight, clean, and free of corrosion or water damage. A module from a vehicle with significant collision or water damage should be avoided.

3. Factor in Programming Costs

Remember that the price of the used part is not the final cost. You must budget for professional programming, which can add $120 to $250 to the total repair cost, depending on shop labor rates.

Estimated Costs

Prices can vary based on location and supplier. The primary difference in part cost is based on whether the vehicle has power tilt/telescoping features.
