Action Taken When the DTC Sets
WARNING: This page is about a different variant/trim than selected.
- The TCM will store the DTC when a failure is detected on the first ignition cycle.
- The TCM will illuminate the HOLD lamp.
- The TCM can no longer determine the validity of any information it may or may not receive from the ECM. Therefore the TCM substitutes default values for engine speed, throttle position, and other engine data signals.
- Transmission operation will be reduced, affecting shift points, torque converter clutch operation, and other driveability concerns.
