Check Engine Light Reset

The check engine light reset process for a 2016 Ram Promaster Window Van requires more than clearing codes — it requires confirming the underlying issue is resolved. Factory scanners at Larry H.

Our technicians diagnose root causes, repair with OEM parts when necessary, and then verify the fix by completing drive-cycle and readiness checks before resetting the light. Resetting the light without repair can mask returning faults and may lead to failed emissions tests, reduced fuel economy, or progressive damage. Choosing dealership service ensures warranty integrity, transparent documentation, and longer-term protection for critical components; warranty-covered repairs must be performed at a certified dealership to remain valid. We offer service financing to spread cost, and you can check current service specials to save.
