Frequently Asked Questions
Can I drive with code U0150?
Yes. This code only affects the passenger power seat. All other vehicle systems remain fully operational.

Potentially. On some vehicles, the seat control module communicates occupancy detection data to the airbag system. If U0150 is set, the passenger airbag status indicator should be checked.
What causes U0150?
A failed passenger seat module or damaged wiring under the passenger seat are the most common causes. Items stored under the passenger seat can damage the wiring harness over time.
