2020-2021 Jeep Compass Heated Steering Wheel Module: Programming, Failures, and Replacement
Diagnose a failing heated steering wheel, understand the critical programming requirements, and learn how to choose a reliable used module for your Compass.
- This module MUST be programmed to the vehicle using a "Proxy Alignment" procedure after installation.
- Failure to perform the Proxy Alignment will result in a non-functional part and a flashing odometer.
- Ensure the part number matches your vehicle's options: this module is for models WITH a heated wheel but WITHOUT ventilated seats.
- The most common failure symptom is the heater turning on for a few seconds and then shutting itself off.
- Part number 68438356AF is the latest, most updated version of this module.
Symptoms of a Failing Heated Steering Wheel Module
When the heated steering wheel module begins to fail, the symptoms are usually straightforward and related directly to the heating function. You will likely not experience any issues with the vehicle's drivability.
- Heated Steering Wheel Doesn't Turn On: The most common symptom is a complete lack of function. When you press the heated steering wheel icon on the Uconnect screen, nothing happens, and the wheel remains cold.
- Function Turns On, Then Immediately Off: Many owners report that when they activate the heated wheel, the indicator light comes on for a few seconds and then turns off by itself. This often points to a short circuit or a fault detected by the module, causing it to shut down as a safety measure.
- Intermittent Operation: The heated wheel may work sometimes but not others, indicating a developing internal fault, a loose connection, or a problem with the related clockspring wiring.
- Warning Lights or Messages: A failure in the module can trigger a warning message on the instrument cluster, such as "Steering Wheel Heater Fault."
- Associated OBD-II Codes: While a generic scanner may not pull specific codes, a more advanced tool might find codes related to the module. A common code for loss of communication with this module is U0229 (Lost Communication With Heated Steering Wheel Module). Other body codes in the B159x range, like B159D, can also be related to heated wheel circuit faults.
Pro Tip: Before condemning the module, check for simple issues. A low battery can cause the vehicle's load-shedding system to disable non-essential features like the heated steering wheel. Also, inspect the fuse for the heated wheel circuit.
Known Issues, TSBs, and Recalls
As of this writing, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Jeep directly addressing the failure of the heated steering wheel module for the 2020-2021 Compass. Most issues appear to be isolated electronic failures. The primary cause of failure is often related to internal module faults or issues with the clockspring, which contains the wiring that flexes as the steering wheel turns.
Programming and Installation Requirements
This is the most critical part of replacing this module. You cannot simply swap the part and expect it to work. On modern FCA/Stellantis vehicles like the 2020-2021 Compass, a procedure called Proxy Alignment (or Proxi Configuration) is required after installing a new module.
A Proxy Alignment is a diagnostic procedure that synchronizes the configuration of all electronic modules in the vehicle with the master configuration stored in the Body Control Module (BCM). If you install a new module without performing this alignment, the vehicle's network will detect a mismatch. This can cause a flashing odometer, various warning lights, and the new part (and sometimes other features) will not function correctly.
This procedure requires a compatible high-level diagnostic scan tool, such as the factory wiTECH tool used by dealers, or advanced aftermarket tools like Autel, Launch, or software like AlfaOBD. 🎬 Watch: How a PROXI alignment is performed using AlfaOBD A standard OBD-II code reader cannot perform a Proxy Alignment. This means a visit to a dealership or a well-equipped independent repair shop is almost always necessary after installation.
Warning: Because 2018 and newer Jeep vehicles have a Secure Gateway Module (SGW), the scan tool needs a special bypass cable or an authorized account to perform configuration changes like a Proxy Alignment.
Buying a Used Heated Steering Wheel Module
A used OEM module is an excellent, cost-effective alternative to a new part, especially since aftermarket options are virtually nonexistent. Here’s what to look for:
- Verify Compatibility: This is crucial. The module 68438356AF (and its predecessors) is for vehicles equipped with a heated steering wheel but WITHOUT ventilated seats. Installing the wrong module will cause a configuration mismatch and a failed Proxy Alignment. Always match the part number or verify compatibility with the vehicle's specific options.
- Inspect the Part Numbers: The part numbers for this module have been updated over time (superseded). The sequence is 68438356AB -> AC -> AD -> AE -> AF. The latest number, 68438356AF, is the most revised version and is the best choice if available. It will have the most up-to-date hardware and firmware fixes from the manufacturer.
- Physical Inspection: When you receive the used module, check the connector pins for any signs of corrosion, bending, or damage. Ensure the plastic housing is not cracked or showing signs of water intrusion.
- Source from a Reputable Recycler: Buy from a seller that offers a warranty and guarantees the part is tested and functional. This protects you in case you receive a defective unit.
Cost Breakdown
Prices can vary, but this table provides a general estimate for replacing the heated steering wheel module.
| Part or Service | Estimated Cost |
|---|---|
| New OEM Module | $80 - $115 |
| Used OEM Module | $40 - $75 |
| Shop Labor (Installation & Programming) | $150 - $300 |
Note: Labor costs include the physical installation of the module (often located under the steering column) and the necessary Proxy Alignment procedure.
Frequently Asked Questions (FAQ)
Does the heated steering wheel module need to be programmed?
Yes, absolutely. After installation, the vehicle requires a "Proxy Alignment" procedure to recognize and configure the new module. Without this step, the module will not work, and you may see a flashing odometer or other warning lights.
Where is the heated steering wheel module located on a 2020-2021 Jeep Compass?
The module, often called the Heated Seat Module (as it controls both functions), is typically located under the dashboard in the area of the steering column. Access usually involves removing the lower dash trim panel beneath the steering wheel.
Can an independent mechanic replace and program this module?
Yes, provided the mechanic has an advanced diagnostic scan tool capable of performing a Proxy Alignment on FCA/Stellantis vehicles and a method to bypass the Secure Gateway Module (SGW). Not all independent shops have this equipment, so you should confirm with them before scheduling the repair.
My heated wheel button turns on for 3 seconds then shuts off. Is the module bad?
This is a classic symptom of a fault in the heated steering wheel circuit. The module is detecting a problem (like a short in the heating element, a bad clockspring, or an internal fault) and is shutting down power as a precaution. While the module itself could be the cause, the problem could also be the clockspring or the heating element within the steering wheel. Proper diagnosis is needed to pinpoint the exact failed component.
