This code means that the car's computer thinks there's a problem with how the back wheels are turning or sliding when you drive. It's like the car is having trouble keeping the back wheels steady.
The code C1155 indicates an issue with the vehicle's system that controls the rear axle's slip angle, which is important for stability and handling.
The C1155 code is triggered when the vehicle's stability control system detects a problem with the rear axle's slip angle control. This system helps ensure the vehicle remains stable during turns and slippery conditions by adjusting the angle of the rear wheels. If the system is not performing as expected, this code is set.
• Warning light on the dashboard
• Poor handling or stability
• Unusual tire wear
• Faulty rear wheel speed sensor
• Malfunctioning stability control module
• Damaged or worn-out suspension components
Slip Angle: The angle between the direction a wheel is pointing and the direction it is actually moving.
Stability Control: A system that helps maintain vehicle control during extreme steering maneuvers.
• Check for any stored codes and freeze frame data.
• Inspect the rear wheel speed sensors and connections.
• Test the stability control module for proper operation.
• Replace faulty rear wheel speed sensor.
• Repair or replace damaged suspension components.
• Reprogram or replace the stability control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Consult a professional mechanic for diagnosis and repair.
Check vehicle warranty for coverage on stability control system components.
This code has been associated with vehicles that have advanced stability control systems, particularly in models with a focus on off-road capabilities.
Moderate – This issue can affect vehicle handling and should be addressed to ensure safety.
Ignoring this code may lead to reduced vehicle stability and increased risk of accidents.
• Vehicle driven on a slippery surface
• Sharp turns or sudden maneuvers
The rear wheel speed sensors are typically located at the wheel hubs, while the stability control module is often found under the hood or beneath the dashboard.
