What is C08C6?

The Diagnostic Trouble Code (DTC) C08C6 refers to a communication issue between the vehicle's control modules, specifically relating to the Electronic Power Steering (EPS) system. When this code appears, it indicates that the Power Steering Control Module (PSCM) is not receiving expected data from other onboard systems. This can lead to a range of issues, from a malfunctioning steering system to a complete loss of power steering functionality. The impact of this code is significant as it directly affects the vehicle's handling and safety. If you notice this code, it’s crucial to address it promptly, as driving without proper steering assistance can be dangerous. The code is most commonly reported in vehicles like the 2015-2020 Jeep Cherokee and the 2015-2020 Ram 1500. Owners might experience symptoms such as difficulty steering, warning lights illuminating on the dashboard, or even an unexpected loss of power steering while driving. Proper diagnosis and repair are essential for safe vehicle operation.

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

Symptoms

Common symptoms when C08C6 is present:

  • Check engine light stays on constantly, indicating potential issues with the power steering control module.
  • Steering feels heavy or unresponsive, making it difficult to maneuver the vehicle, especially at low speeds.
  • Inconsistent power steering performance, where it may work intermittently and then suddenly fail.
  • Audible warning chimes may occur, alerting the driver to a problem with the steering system.
  • Dashboard displays error messages related to steering assist, further indicating a need for immediate diagnostic attention.

Possible Causes

Most common causes of C08C6 (ordered by frequency):

  1. The most common cause of code C08C6 is a faulty Power Steering Control Module (PSCM), with a likelihood of about 60%. This module may fail due to electrical issues or corrosion.
  2. Wiring issues, such as frayed or damaged wires in the EPS harness, can cause communication failures. This is the second most common cause, accounting for approximately 25% of cases.
  3. Software glitches in the vehicle's control modules can disrupt communication. Keeping the vehicle's software updated is essential to prevent this issue.
  4. Less commonly, the EPS motor itself can fail, leading to severe steering issues. This is a more serious cause and should be addressed immediately.
  5. In rare cases, issues with the vehicle's battery or alternator can cause low voltage problems affecting the PSCM's operation.
