C1288 Buick Code - Steering Sensor Circuit Malfunction
Quick Answer
The Vehicle Stability Enhancement System (VSES) is activated by the Electronic Brake Control Module (EBCM) calculating the desired yaw rate and comparing it to the actual yaw rate input. Common causes include Faulty Steering Wheel Position Sensor (SWPS), Faulty Electronic Brake Control Module (EBCM), Steering Wheel Position Sensor (SWPS) harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1288 Buick Description
The amount of differential braking applied to the left or right front wheel is based on both the yaw rate error and side slip rate error. The side slip rate error is a function of the lateral acceleration minus the product of the yaw rate and vehicle speed. The yaw rate error and side slip rate error are combined to produce the total delta velocity error. When the delta velocity error becomes too large and the VSES system activates, the drivers steering inputs combined with the differential braking will attempt to bring the delta velocity error toward zero.
The VSES activations generally occur during aggressive driving, in the turns or bumpy roads without much use of the accelerator pedal. When braking during VSES activation, the brake pedal will feel different than the ABS pedal pulsation. The brake pedal pulsates at a higher frequency during VSES activation.
What are the Possible Causes of the DTC C1288 Buick?
- Faulty Steering Wheel Position Sensor (SWPS)
- Faulty Electronic Brake Control Module (EBCM)
- Steering Wheel Position Sensor (SWPS) harness is open or shorted
- Steering Wheel Position Sensor (SWPS) circuit poor electrical connection
How to Fix the DTC C1288 Buick?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the C1288 Buick code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about C1288 Buick Code
1. What does the OBDII code C1288 mean on a Buick?
C1288 indicates a Steering Sensor Circuit Malfunction, which means the vehicle's Electronic Brake Control Module (EBCM) has detected an issue with the steering angle sensor or its circuitry.
2. What are the common symptoms of code C1288 in a Buick?
Symptoms may include the ABS or traction control warning light being illuminated, loss of power steering assist, or difficulty with stability control functions.
3. What causes the C1288 code to appear in a Buick?
Common causes include a faulty steering angle sensor, damaged wiring or connectors in the sensor circuit, or issues with the Electronic Brake Control Module (EBCM).
4. How is the C1288 code diagnosed on a Buick?
A mechanic will use a scan tool to read the code and analyze live data from the steering angle sensor, followed by inspecting the sensor, wiring, and connectors for damage or faults.
5. Can I drive my Buick with a C1288 code?
It’s possible to drive, but not recommended. Reduced stability control and ABS functionality can make handling and braking less effective, especially in slippery conditions.
6. How do you fix a C1288 code on a Buick?
Repairs may involve replacing the steering angle sensor, repairing damaged wiring or connectors, or reprogramming or replacing the EBCM if necessary.
7. Is the steering angle sensor calibration required after replacing it?
Yes, after replacing the steering angle sensor, it must be calibrated using a scan tool to ensure proper functionality.
8. What tools are needed to repair the C1288 code on a Buick?
A diagnostic scan tool capable of reading ABS and stability control systems, a multimeter for testing wiring, and possibly tools for removing and replacing the steering angle sensor.
9. How much does it cost to fix the C1288 code on a Buick?
Repair costs can range from $150 to $500 or more, depending on whether the issue is with the sensor, wiring, or EBCM.
10. Can a low battery cause the C1288 code in a Buick?
Yes, a low or weak battery can sometimes cause electrical issues, including triggering the C1288 code, by disrupting proper communication in the system.
