Action Taken When the DTC Sets
WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
The TCM will not request the illumination of the malfunction indicator lamp (MIL) or hold lamp, but will store the DTC when the TCM detects a failure on the first ignition cycle.
