Action Taken When The DTC Sets
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.
TCM performs the following actions if DTC is set:
- While diagnostic response is active, one of the following conditions can occur: If the gearshift lever is moved to Neutral, then the transmission will shift to Neutral. If the gearshift lever is moved to Reverse, then the transmission will shift to Reverse. If the gearshift lever is moved to a forward gear range, then the transmission will shift to 3rd or 5th gear unless the transmission is compromised by overspeeding or direction change (then the transmission will shift to Neutral).
- DTC will be stored in the TCM history.
- The TCM freezes shift adapts.
- Illuminates the MIL when active.
- Due to this failure and associated response, DTC P0722 and DTC P0845 also set.
- TCM inhibits TCC engagement.
