Circuit Description
WARNING: This page is about a different variant/trim than selected.
The transmission control module (TCM) continuously monitors the system voltage on the Ignition 1 and the battery circuits. Lower than normal voltage may be inadequate to operate the transmission control solenoids properly. Improper solenoid operation may cause erratic transmission operation and tie-up conditions, which may result in internal damage.
When the TCM detects low voltage, DTC P0562 sets. DTC P0562 is a type C DTC.
