What is U0208?

The diagnostic trouble code (DTC) U0208 signals that there is a loss of communication between the vehicle's control modules, specifically the Seat Control Module. This code typically indicates that the powertrain control module (PCM) is unable to communicate with the seat module due to various issues such as wiring problems, module failure, or software glitches. When the PCM and seat control module fail to communicate, the features associated with the seat, such as power adjustments, memory settings, and heating/cooling functions, may not work correctly. This can lead to discomfort for drivers and passengers, particularly if the seat adjustments are not functioning. In some cases, the check engine light may illuminate, and other warning lights may also appear on the dashboard. Ignoring this issue can lead to more severe electrical problems, impacting various systems in the vehicle. If you encounter this code, it's essential to address it promptly to ensure all seat functionalities operate correctly, maintain vehicle safety, and avoid escalating repair costs.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0208 is present:

  • Check engine light activates and remains lit, indicating an underlying issue with the vehicle's electrical system.
  • Seat adjustments become non-responsive; drivers may find it difficult to adjust their seating position or memory settings.
  • Heating or cooling features of the seat fail to operate, leading to discomfort especially in extreme weather conditions.
  • Other electrical features associated with the seat, such as lumbar support, may also malfunction.
  • An unusual noise may occur when attempting to adjust the seat, suggesting possible mechanical failure.

Possible Causes

Most common causes of U0208 (ordered by frequency):

  1. The most common cause of U0208 is damaged wiring or connectors, accounting for about 60% of cases. Over time, vibration and exposure can lead to wear and tear on the wiring.
  2. Another frequent cause is a failed seat control module itself, which can occur due to manufacturing defects or exposure to moisture, generally seen in about 25% of cases.
  3. Software glitches in the PCM can also lead to communication loss, especially after updates or repairs; this occurs in approximately 10% of cases.
  4. Less commonly, issues with the PCM itself can prevent communication with the seat control module, which is more serious and requires immediate attention.
  5. Rarely, a short circuit in the electrical system due to improper modifications can cause the U0208 code, potentially leading to extensive damage if not addressed.
