What is C17C2?

DTC code C17C2 pertains to a specific issue related to the vehicle’s ABS (Anti-lock Braking System) module, particularly indicating a communication fault between the ABS control module and the vehicle's powertrain control module (PCM). This can lead to various braking system problems, compromising safety by preventing the ABS from functioning properly. If you are driving a 2015-2018 Honda Accord, this code may illuminate your check engine light and could manifest as a lack of ABS functionality during braking. In practical terms, this means you may experience increased stopping distances, especially in slippery conditions, as your vehicle will revert to standard braking mode without the enhanced control provided by the ABS. Ignoring this code could lead to further complications, including potential damage to other components of the braking system or even failure to pass state inspections. It’s essential to address this code promptly to ensure your vehicle’s safety and reliability on the road.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C17C2 is present:

  • The check engine light or ABS warning light stays on constantly, indicating a fault in the braking system.
  • Driver may feel a difference in braking performance, such as the brakes feeling less responsive or requiring more pressure to stop.
  • You might notice a decrease in fuel economy, potentially by 10-15%, due to the increased demand on the vehicle's powertrain.
  • The ABS system may fail to engage during hard braking, which could increase stopping distances on slick roads.
  • In some cases, you may experience erratic ABS warning light behavior, turning on and off without a clear pattern.

Possible Causes

Most common causes of C17C2 (ordered by frequency):

  1. The most common cause of the C17C2 code is a faulty ABS control module, with an approximate likelihood of 60%. This can result from electrical issues, water intrusion, or internal failure of the module.
  2. Another potential cause is damaged wiring or poor connections between the ABS module and the PCM, which can happen due to corrosion or wear over time.
  3. A third cause might be software issues within the ABS control module itself. Regular updates to the vehicle's software can help prevent this.
  4. Less commonly, a faulty PCM can trigger this code, which is a more serious issue as it affects multiple systems within the vehicle.
  5. A rare but possible cause is an issue with the vehicle's CAN (Controller Area Network) bus, which could disrupt communication among various modules.
