Action Taken When The DTC Sets
WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 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, 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; and if the gearshift lever is moved to a forward gear range, then the transmission will shift to 3rd or 5th range 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.
