Honda Odyssey Check Engine Light Due to Front Collision Warning System Failure After Restart on Honda Odyssey

Problem overview

Some Honda Odyssey owners report experiencing issues when the check engine light activates due to a front collision warning system (FCW) failure. This warning may indicate problems such as malfunctioning sensors, damaged wiring, or a failed control module. While restarting the vehicle might temporarily alleviate the issue, it is crucial for owners to diagnose the problem promptly to maintain safety and functionality. The FCW warning light suggests a malfunction in the forward collision warning system, and using a code scanner to check for trouble codes is recommended to pinpoint the specific cause. Additionally, some owners note that while the check engine light can illuminate for unrelated reasons, a more serious issue may trigger both the check engine light and the FCW system failure. Owners are advised to inspect sensors for obstructions and consider factors such as adverse weather, faulty sensors or cameras, damaged wiring, blown fuses, or software issues that could lead to FCW system failures. Addressing these concerns promptly is essential for the safe operation of the Honda Odyssey.
