2011 Jeep Grand Cherokee Steering Column Module: Decoding Widespread Electrical Failures

Symptoms of a Failing 2011 Grand Cherokee Steering Column Module

Failure of the Steering Column Control Module (SCCM) on the 2011 Grand Cherokee often presents as a bizarre and cascading series of electrical problems. Because the module controls so many different functions, symptoms can appear unrelated at first, making diagnosis confusing. A failing SCCM is the likely culprit if you experience a combination of the following issues.

• Steering Wheel Controls Stop Working: Often, the first sign is the buttons on one or both sides of the steering wheel (for radio, cruise control, or phone) becoming intermittent or failing completely.
• Horn Failure: The horn may stop working at the same time as the steering wheel controls.
• Turn Signal and Wiper Malfunctions: Turn signals may not activate, or the windshield wipers may turn on by themselves and refuse to turn off. In some cases, the wipers may not work at all.
• Traction Control Light: A warning light for the Traction Control or Electronic Stability Control (ESC) system may illuminate on the dashboard. This is often due to the loss of data from the integrated Steering Angle Sensor.
• Interior and Exterior Lighting Problems: Headlights may turn on and stay on, and interior dome lights may stop working.
• Warning Chimes and Dashboard Messages: The vehicle may display messages like "Key Not Programmed" or other warnings on the instrument cluster.

Common Diagnostic Trouble Codes (DTCs)

A professional scan tool may reveal the following codes, which strongly point to a faulty SCCM:

• U0126 - Lost Communication With Steering Angle Sensor Module: This is a very common code when the SCCM fails. Since the Steering Angle Sensor (SAS) is part of the SCCM assembly, a failure of the module or its ability to communicate on the vehicle's network will log this code.
• C0051 - Steering Wheel Position Sensor: This code indicates a fault with the SAS itself, its calibration, or its circuitry. It often triggers ABS and ESC warning lights. After replacement, a calibration procedure with a compatible scan tool is required to clear this code.
• U112D-00 - Lost communication with EVIC steering wheel switches: This code specifically indicates a loss of communication between the module and the steering wheel buttons.

Known Issues, TSBs, and Recalls

While there are no major recalls specifically for SCCM failure on the 2011 model, its electrical system was the subject of other service actions.

• Technical Service Bulletin (TSB) #05057980A: This bulletin instructs technicians to verify which steering column is installed in the vehicle before ordering a replacement. It highlights that multiple versions of the part exist and that a flowchart must be used to select the correct one, confirming the importance of matching part numbers to the vehicle's specific options.
• Related Recall W53: While not for the SCCM itself, this safety recall was issued for some Jeep models due to the Electronic Steering Lock (ESL) wiring harness potentially rubbing against the steering column shaft. This could cause damaged wires, leading to a loss of power steering or motive power. This highlights the tight packaging and potential for wiring issues within the steering column.

Programming and Installation Requirements

Replacing the SCCM is not a simple plug-and-play repair. Programming is mandatory for the part to function correctly and communicate with the vehicle's other electronic modules.

VIN Programming is Required: Every module on a modern vehicle, including the SCCM, is programmed with the car's Vehicle Identification Number (VIN). This acts as a digital signature, allowing all the computers to recognize and trust each other.

• New Modules: A brand new SCCM from the dealer is a blank slate. It must be installed and then programmed with the vehicle's VIN using a dealership-level diagnostic tool, like wiTECH.
• Used Modules: A used SCCM already has the VIN from its donor vehicle stored in its memory. It cannot be simply installed in another car. The old VIN must be erased and the new vehicle's VIN written to the module. This requires specialized equipment and knowledge, and not all independent shops can perform this service.

Buying a Used 2011 Grand Cherokee Steering Column Module

Given the high cost of a new module, a used OEM part can be an excellent value. However, there are critical details to be aware of to ensure you get the right part.

1. Match the Part Number EXACTLY: This is the most important rule. As confirmed by a TSB, multiple versions of the SCCM exist for the 2011 Grand Cherokee, depending on options like a heated steering wheel, power tilt/telescoping column, and specific trim levels. Do not buy a part that "looks similar." You must physically inspect your original module and match the Mopar part number (e.g., 05026788AE, 1HE80HL9AO, etc.) precisely.
2. Verify Compatibility with your VIN: When buying from a reputable seller, provide your VIN to confirm fitment. Many dealer sites require a VIN to order a new module because of the high number of variations.
3. Inspect Connectors and Wiring: When you receive the used part, carefully inspect all plastic connector housings and pins. Look for any signs of corrosion, bent pins, or damage to the integrated wiring pigtails.
4. Budget for Programming: Remember that a used module is not plug-and-play. You must factor in the cost of having a professional shop install and program the part to your vehicle's VIN. Call local shops beforehand to confirm they have the capability to program a used Chrysler module.
5. Why Used OEM is a Strong Choice: Direct aftermarket replacements for the complete SCCM assembly are not widely available from major brands. Your main choices are a very expensive new OEM part or a recycled OEM part. A used OEM module that is correctly identified and professionally installed can provide the same performance as a new one for a fraction of the price.
