Common Questions
What does C087E mean and how does it affect my car?
DTC C087E indicates a fault in your vehicle’s Electronic Brake Control Module, which is crucial for the operation of your braking system. If this code appears, it can affect your car's ability to brake effectively, potentially leading to unsafe driving conditions. It's important to address this issue promptly to maintain your vehicle's safety features.
What are the most common causes of C087E and how much does it cost to fix?
Common causes of the C087E code include a faulty brake pressure sensor and damaged wiring. Repair costs can range from $150 for sensor replacement to over $1,200 for EBCM replacement. It's advisable to have a professional inspection for an accurate diagnosis.
Can I drive my car with C087E or should I stop immediately?
It is not recommended to drive your vehicle if the C087E code is present, as it can compromise your braking system. Ignoring this code could lead to brake failure, which poses significant safety risks. It’s best to have your vehicle inspected as soon as possible.
How can I diagnose C087E myself using GeekOBD APP?
To diagnose C087E, download the GeekOBD APP on your smartphone. Connect it to your OBD2 port and retrieve the diagnostic codes. The app will provide freeze frame data and history, helping you understand the context of the fault. From there, you can perform visual inspections and component tests as needed.
What vehicles are most commonly affected by C087E?
DTC C087E is most prevalent in 2015-2018 Chevrolet Silverado models and similar models from GMC. These vehicles often experience brake system issues related to the EBCM and related sensors.
How can I prevent C087E from happening again?
To prevent the C087E code from recurring, ensure regular maintenance of your braking system, including checking brake fluid levels and replacing worn components. Additionally, inspect wiring and connectors for signs of corrosion or damage during routine service.
What is C087E?
DTC C087E refers to a problem detected by the Electronic Brake Control Module (EBCM) in vehicles, particularly common in the 2015-2018 Chevrolet Silverado. This code indicates that the EBCM has detected a fault in the system monitoring the brake pressure or the operation of the brake pedal sensor. This can lead to various issues, including problems with the ABS (Anti-lock Braking System), traction control, and stability control features of your vehicle. When this code is triggered, it essentially means that the EBCM is not receiving the expected signals from the brake pressure sensor or has detected an inconsistency in the system's operation. If left unaddressed, this can result in reduced braking performance and could potentially make your vehicle less safe to drive. Car owners should take this code seriously, as it often illuminates the check engine light or the ABS warning light on the dashboard. Ignoring it could lead to more extensive repairs and safety hazards. Regular diagnostic checks using tools like the GeekOBD APP can help catch such issues early, allowing for timely repairs and ensuring your vehicle operates safely and efficiently.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C087E is present:
- The check engine light or ABS warning light remains illuminated on the dashboard, indicating a system malfunction.
- Unusual braking behavior, such as the brakes feeling spongy or unresponsive, which can affect driver confidence.
- A noticeable decline in braking performance, which may include longer stopping distances during normal driving conditions.
- Increased pedal travel, meaning you have to press the brake pedal down further than usual to engage the brakes.
- Traction control or stability control systems may deactivate, leading to reduced vehicle stability in adverse conditions.
Possible Causes
Most common causes of C087E (ordered by frequency):
- The most common cause of DTC C087E is a faulty brake pressure sensor, which has a likelihood of about 60%. This sensor measures the brake fluid pressure and sends the signal to the EBCM.
- Another frequent cause is damaged or corroded wiring in the brake control system. This can interfere with signal transmission, leading to erroneous readings.
- Brake fluid contamination or low fluid levels can cause performance issues; ensuring the braking system is properly maintained can prevent this.
- Less commonly, a malfunctioning EBCM itself may trigger this code, which could require replacement if diagnosed correctly.
- Rarely, issues with the vehicle's ABS module can also cause this code to appear, which typically requires advanced diagnostics to resolve.
