Code B1E28 Description
The B1E28 diagnostic trouble code (DTC) indicates a problem with the 3rd row seat normal/stow switch circuit being detected as low. This code is typically found in vehicles equipped with power-folding 3rd-row seats. The switch circuit is responsible for controlling the movement of the 3rd-row seats between their normal seating position and the stowed position to create additional cargo space. When this circuit is detected as low, it means that there is an issue with the electrical signal being sent to the control module, causing the system to malfunction.
Common Causes of B1E28
- Faulty normal/stow switch in the 3rd-row seat.
- Damaged wiring or connectors in the switch circuit.
- Corrosion or poor connections in the electrical system.
- Issues with the control module interpreting the switch signals.
- Electrical short circuits within the system.
Symptoms of B1E28
- Inability to move the 3rd-row seats between normal and stowed positions.
- Unresponsive switch when attempting to adjust the 3rd-row seats.
- Warning light illuminated on the dashboard related to the 3rd-row seat system.
- Audible clicking or grinding noises when trying to operate the 3rd-row seats.
How to Fix B1E28
- Begin by diagnosing the specific cause of the B1E28 code using a scan tool to pinpoint the faulty component.
- Inspect the normal/stow switch for any visible damage or signs of wear, replacing it if necessary.
- Check the wiring harnesses and connectors for any breaks, corrosion, or loose connections, repairing or replacing them as needed.
- Test the control module to ensure it is functioning correctly and receiving the proper signals from the switch circuit.
- Clear the DTC from the system memory after completing the repairs and test the 3rd-row seat system to verify proper operation.
Cost to Fix B1E28
The typical repair costs for addressing the B1E28 code can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, replacing a faulty normal/stow switch or repairing wiring/connectors may range from $100 to $300, including parts and labor. However, if the control module needs to be replaced or additional electrical work is required, the costs can increase accordingly.
