Circuit Description

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control module (TCM) continuously monitors the system voltage on the Ignition 1 circuits. Lower than normal voltage may be inadequate to operate the transmission control solenoids properly. Improper solenoid operation may cause erratic transmission operation, which may result in internal damage.

When the TCM detects low voltage, DTC P0562 sets. DTC P0562 is a type A DTC.
