Circuit Description
WARNING: This page is about a different variant/trim than selected.
The transmission control module (TCM) samples the system voltage on the Ignition 1 circuit every 0.1 seconds. 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.
If the TCM detects low voltage, DTC P0562 sets. DTC P0562 is a type A DTC.
