Fail-Safe Table

WARNING: This page is about a different car, the 2007 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.

When any of the following DTCs is detected, ECM enters fail-safe mode as long as malfunction continues to exist but that mode is canceled when ECM detects normal condition after that.
