What is C0B35?
The Diagnostic Trouble Code (DTC) C0B35 indicates an issue with the driver seat position sensor circuit in your vehicle, specifically related to range or performance problems. This code typically arises when the vehicle's onboard diagnostic system detects that the seat position sensor is providing readings that are outside of the expected range. This sensor is crucial for ensuring that the seat is positioned correctly for optimal driver comfort and safety, as well as for the proper functioning of advanced features like airbags and seat belt tensioners. When the seat position sensor fails or sends incorrect data, it can lead to various issues including improper airbag deployment or even a lack of seat adjustment capabilities, which could affect driving comfort. This code can be particularly common in vehicles like the 2016-2020 Toyota RAV4 and 2017-2021 Ford F-150, where advanced technology is integrated into seating systems. Ignoring this code could lead to more severe problems down the line, including safety risks and increased repair costs. Therefore, understanding the implications of DTC C0B35 is essential for maintaining your vehicle's functionality and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0B35 is present:
- The check engine light illuminates, indicating a fault in the vehicle's sensor systems.
- Driver's seat adjustment controls may become unresponsive, making it difficult to achieve a comfortable driving position.
- Inconsistent airbag warning lights may appear, suggesting potential safety issues related to airbag deployment.
- Seat position memory settings may not work correctly, which can be frustrating for drivers who share a vehicle.
- Unusual noises from the seat adjustment mechanism, which may indicate a mechanical fault.
Possible Causes
Most common causes of C0B35 (ordered by frequency):
- The most common cause of C0B35 is a faulty driver seat position sensor, which can account for about 60% of cases. Over time, wear and tear or electrical issues can lead to sensor failure.
- A second cause could be damaged wiring or connectors in the seat adjustment circuit, which can disrupt the sensor’s operation. This can occur due to frequent seat adjustments or improper installation of aftermarket seats.
- A third cause might be a fault in the body control module (BCM) that receives and processes the seat position data. Keeping the BCM updated can prevent these issues.
- Less commonly, a defective seat adjustment motor could cause the sensor to read incorrectly. Regular maintenance checks can help catch mechanical faults early.
- In rare cases, software glitches in the vehicle's onboard computer can lead to erroneous readings from the seat position sensor.
