Warm-up Cycles

WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

If fault that caused DTC to set is repaired, ECM will begin to count warm-up cycles. After 40 consecutive warm-up cycles with no further faults, ECM will automatically clear DTC from memory.
