2015 Kia K900 Steering Column Control Module: Diagnosing Failures and Replacement Guide

Symptoms of a Failing 2015 Kia K900 Steering Column Control Module

Diagnosing a faulty Steering Column Control Module (SCCM) can be tricky because its symptoms often overlap with other parts in the steering column, like the clock spring or multifunction switch. The most common signs point to a loss of electrical functions controlled by the module.

• Power Tilt/Telescopic Failure: The most direct symptom for part number 954503T001 is the inability to adjust the steering wheel's position up, down, in, or out.
• Unresponsive Steering Wheel Buttons: Buttons for cruise control, audio volume, track selection, or phone calls may stop working entirely or work only intermittently.
• Horn Failure: The horn may become inoperable, which is a significant safety issue. This often happens in conjunction with other button failures.
• Airbag Warning Light: While more commonly associated with a bad clock spring, the SCCM can be part of the communication path for the airbag system. An airbag warning light appearing with other steering wheel electrical issues can point to a problem in the column.
• Associated OBD-II Codes: While specific codes for this module on the K900 are not widely documented, network communication codes starting with 'U' (like U0537 - Invalid Data Received From Column Lock Module) can indicate a module failure.

Differentiating Between the SCCM and a Bad Clock Spring

Many symptoms of a bad SCCM are identical to those of a failing clock spring. The clock spring is a coiled ribbon cable directly behind the steering wheel that maintains electrical connections as the wheel turns. A key diagnostic tip is to test the non-functional buttons while turning the steering wheel from lock to lock. If the buttons work at certain angles but not others, the clock spring is the most likely culprit due to a break in its internal ribbon. If the functions are completely dead regardless of wheel position, the SCCM or a fuse is a more likely cause.

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

As of mid-2026, there are no recalls or Technical Service Bulletins (TSBs) issued by Kia or the NHTSA that specifically address the Steering Column Control Module (part 954503T001) for the 2015 Kia K900.

It is important not to confuse other recalls with an SCCM issue:

• NHTSA Recall 16V-288 (Kia SC130): This recall concerned the headlight multifunction switch on the steering column, which could cause headlights to flicker. It did not involve the internal control module.
• NHTSA Recall 23V652: This recall was for a potential electrical short in the Hydraulic Electronic Control Unit (HECU) for the ABS, which could pose a fire risk. This part is unrelated to the steering column.

Programming and Calibration Requirements

A critical question for any electronic module replacement is whether it requires programming. While there is no definitive statement found for this specific part on the 2015 K900, it is highly likely that a replacement module will require some form of programming or calibration by a dealer or a qualified independent shop.

Modern vehicle modules are often coded to the car's Vehicle Identification Number (VIN) and its specific set of options. A used module from a donor car may have different settings. At a minimum, a replacement may require a "variant coding" procedure or calibration of the steering angle sensor. This is typically done using Kia's proprietary Global Diagnostic System (GDS) software, which requires a subscription to `kiatechinfo.com` and a compatible J2534 Pass-Thru device. Failure to program the module correctly could result in it not functioning properly.

Buying a Used 2015 K900 Steering Column Control Module

Given the significant cost savings, a used OEM module is a popular choice. However, buying a used electronic part requires careful consideration.

• Match the Part Number Exactly: The only way to ensure compatibility is to match the OEM part number. For the 2015 K900, the primary number is 954503T001. Do not rely on visual appearance alone.
• Inspect for Damage: Check the module for any signs of physical damage, especially to the connectors and pins. Bent or corroded pins will cause communication errors. Avoid parts that show signs of water intrusion or heat damage.
• Source from a Reputable Seller: Purchase from a recycled parts seller that offers a warranty and a return policy. This gives you protection in case the part is dead on arrival.
• Understand Programming Needs: Be prepared for the added cost and step of having the used module programmed to your vehicle. Factor this into the total cost of the repair.

Replacement Cost Comparison

The cost to replace the Steering Column Control Module can vary significantly based on the part source and labor rates.

Note: Labor is estimated at 1.5-2 hours. Prices are estimates and do not include taxes or potential programming fees.
