What is C0097?
The diagnostic trouble code (DTC) C0097 indicates a communication error between the Anti-lock Braking System (ABS) control module and other control units in the vehicle. This code is particularly prevalent in models like the 2016-2020 Chevrolet Silverado and 2015-2019 GMC Sierra. When the ABS control module fails to communicate properly, it can lead to several issues, including the inability to engage the anti-lock braking system during critical situations, which can compromise vehicle safety. The warning light on the dashboard may illuminate, alerting the driver to a malfunction. Additionally, if the ABS module is failing, it may not activate during hard braking scenarios, potentially increasing stopping distances and leading to hazardous driving conditions. Drivers may also notice symptoms such as unusual brake pedal behavior, with the pedal feeling spongy or excessively firm, indicating that the ABS system is not functioning as intended. Ignoring this code can lead to further issues, including the malfunction of other safety systems, making it imperative for drivers to address C0097 promptly to ensure vehicle safety and reliability.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0097 is present:
- The ABS warning light remains illuminated on the dashboard, indicating a fault in the braking system.
- Drivers may experience a spongy or excessively hard brake pedal, suggesting that the ABS system isn't functioning correctly.
- There may be noticeable changes in braking performance, such as longer stopping distances when braking hard.
- In some cases, the traction control light may also illuminate, indicating issues with traction control related to the ABS.
- Inconsistent braking behavior can occur, making it difficult to predict how the vehicle will respond during emergency stops.
