C1282 Cadillac Code - Yaw Rate Sensor Bias 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 Yaw Rate Sensor, Faulty Electronic Brake Control Module (EBCM). 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 C1282 Cadillac 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 C1282 Cadillac?
- Faulty Steering Wheel Position Sensor (SWPS)
- Faulty Yaw Rate Sensor
- Faulty Electronic Brake Control Module (EBCM)
- Yaw Rate Sensor harness is open or shorted
- Yaw Rate Sensor circuit poor electrical connection
How to Fix the DTC C1282 Cadillac?
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?

Frequently Asked Questions about C1282 Cadillac Code
1. What does the OBDII code C1282 mean on a Cadillac?
C1282 indicates a Yaw Rate Sensor Bias Circuit Malfunction, which means the electronic stability control system has detected an issue with the yaw rate sensor's bias signal.
2. What are the common symptoms of the C1282 code?
Symptoms include the ABS or stability control warning light illuminating, reduced or disabled stability control functionality, and potential difficulty maintaining vehicle stability during sharp turns or slippery conditions.
3. What causes the C1282 code to appear?
Common causes include a faulty yaw rate sensor, damaged wiring or connectors in the sensor circuit, a loose connection, or issues with the vehicle's electronic control module (ECM).
4. How do I diagnose the C1282 code?
Diagnose this code by scanning the vehicle with an OBDII scanner, checking the yaw rate sensor and its wiring for physical damage, and testing the sensor's bias voltage with a multimeter.
5. Can I drive my Cadillac with the C1282 code?
While the vehicle may still be drivable, driving with this code can compromise stability control and increase the risk of losing control in slippery or emergency situations.
6. How do I fix the C1282 code on a Cadillac?
Repairs may include replacing the yaw rate sensor, repairing or replacing damaged wiring or connectors, and clearing the code with a diagnostic scanner after the issue is resolved.
7. Where is the yaw rate sensor located in my Cadillac?
The yaw rate sensor is typically located under the center console, near the vehicle's center of gravity, but exact placement may vary by model.
8. How much does it cost to fix the C1282 code?
Repair costs can vary widely, ranging from $150 to $600 or more, depending on whether the issue is with the sensor itself, the wiring, or other related components.
9. Can a low battery cause the C1282 code?
Yes, a low or weak battery can sometimes trigger stability control system errors, including the C1282 code, due to inconsistent voltage supply.
10. Do I need to recalibrate the yaw rate sensor after replacing it?
Yes, most vehicles require recalibration of the yaw rate sensor using specialized equipment to ensure the stability control system functions properly.
