This code means there's a problem with the car's computer system that helps keep the car stable. It's like when a video game controller doesn't work right, and you can't control your character properly.
The code C1087 indicates an issue with the Dynamic Stability Control (DSC) system's internal control module, specifically in the valve driver circuit.
The C1087 code is triggered when the DSC control module detects a malfunction in the valve driver circuit. This circuit is responsible for controlling the hydraulic valves that manage the braking pressure to each wheel, ensuring vehicle stability and traction.
• DSC warning light illuminated
• Loss of traction control
• Inconsistent braking performance
• Faulty DSC control module
• Damaged wiring or connectors in the valve driver circuit
• Internal failure of the valve driver circuit
DSC: Dynamic Stability Control
OBD-II: On-Board Diagnostics II
• Perform a visual inspection of the DSC control module and wiring.
• Use a diagnostic scanner to read and clear the code.
• Test the valve driver circuit for continuity and proper operation.
• Replace the DSC control module if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram the DSC control module if necessary.

Control Module Issue
• Drive cautiously as the stability control may not function properly.
• Have the vehicle inspected by a professional as soon as possible.
Check with the manufacturer for warranty coverage on the DSC control module.
The C1087 code has been reported in vehicles with advanced stability control systems, primarily in European models.
High – This issue affects vehicle stability and safety, requiring prompt attention.
Driving with a malfunctioning DSC system can lead to loss of vehicle control, increasing the risk of accidents.
• Vehicle on a flat surface
• Ignition in the 'On' position
The DSC control module is typically located near the vehicle's ABS module, often in the engine bay or under the dashboard.
Q: Can I drive my car with a C1087 code?
A: It's not recommended as the stability control may not work, increasing the risk of losing control of the vehicle.
Q: How do I reset the DSC system?
A: Clearing the code with a diagnostic scanner may reset the system, but it's important to fix the underlying issue first.
