Code U112D Description
The U112D diagnostic trouble code indicates that there is a communication error between the Electronic Vehicle Information Center (EVIC) and the steering wheel switches in the vehicle. The EVIC is responsible for displaying various information to the driver, such as vehicle settings, warnings, and other data. The steering wheel switches allow the driver to interact with the EVIC without taking their hands off the wheel.
Common Causes of U112D
- Faulty wiring or connectors in the communication system
- Malfunctioning EVIC or steering wheel switch module
- Software issues or programming errors
- Electrical interference or signal disruption
- Faulty body control module (BCM)
Symptoms of U112D
- Loss of communication with the EVIC display
- Inability to access certain vehicle settings or information
- Steering wheel controls not functioning properly
- Warning lights related to the EVIC system appearing on the dashboard
How to Fix U112D
- Perform a diagnostic scan using a professional scan tool to identify the exact cause of the communication error.
- Inspect the wiring harness and connectors for any damage or corrosion, repair or replace as needed.
- Check for software updates or reprogramming for the EVIC and steering wheel switch modules.
- Test the communication system between the EVIC and steering wheel switches to ensure proper functionality.
- If necessary, replace the faulty EVIC or steering wheel switch module to restore communication.
Cost to Fix U112D
The typical repair costs for addressing a U112D code can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's recommended to consult local rates for a more accurate estimate.

Frequently Asked Questions about U112D Code
1. What are the common symptoms of OBDII code U112D?
- Common symptoms include a loss of communication with the steering wheel switches, leading to non-functional controls for features like audio, cruise control, and vehicle information displays.
2. What could cause the OBDII code U112D to trigger?
- The code U112D is typically triggered by a communication breakdown between the Electronic Vehicle Information Center (EVIC) module and the steering wheel switches due to issues such as wiring problems, a faulty EVIC module, or a defective steering wheel switch.
3. How can I diagnose the cause of the U112D code?
- Diagnosing the U112D code involves checking the wiring connections between the EVIC module and the steering wheel switches, testing for continuity, inspecting for physical damage, and using a scan tool to analyze communication signals.
4. Is it safe to continue driving with the U112D code present?
- While it may be safe to drive with the U112D code, it is advisable to address the issue promptly to ensure the proper functioning of essential vehicle controls accessed through the steering wheel switches.
5. What are some repair tips for resolving the U112D code?
- Repair tips include checking and repairing any damaged wiring, replacing a faulty EVIC module or steering wheel switch, resetting the system by disconnecting and reconnecting the battery, and performing a relearn procedure if necessary.
6. Can the U112D code be cleared/reset without fixing the underlying issue?
- Clearing or resetting the U112D code without addressing the root cause, such as a wiring fault or a defective component, may result in the code reappearing once the communication issue resurfaces.
7. How much does it typically cost to repair the U112D code?
- The cost of repairing the U112D code can vary depending on the underlying cause and the specific components that need to be replaced. It is recommended to consult a professional mechanic for an accurate diagnosis and cost estimate.
8. Are there any preventive measures to avoid the U112D code in the future?
- Regularly inspecting and maintaining the wiring connections, steering wheel switches, and EVIC module can help prevent issues that may lead to the U112D code. Additionally, following the manufacturer's recommended maintenance schedule is essential.
9. Can a DIY enthusiast fix the U112D code issue?
- DIY enthusiasts with advanced automotive repair skills and access to the necessary tools and diagnostic equipment may be able to address the U112D code issue themselves. However, it is recommended to seek professional help if unsure.
10. Will the U112D code cause the vehicle to fail an emissions test?
- The U112D code itself may not directly cause the vehicle to fail an emissions test, but it is indicative of a communication problem that should be resolved to ensure the vehicle's onboard systems are functioning correctly.
