The transmission control module (TCM) samples the system voltage on the Ignition 1 circuit every 0.1 seconds. Higher than normal voltage may cause the transmission control solenoids to operate improperly or damage the solid-state components inside the TCM.

If the TCM detects high voltage, DTC P0563 sets. DTC P0563 is a type A DTC.
