Code P0658 GMC Description

The Transmission Control Module (TCM) receives information from a variety of sensors, switches, and serial data information from other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio, and torque converter clutch operation. The Transmission Control Solenoid Valves are electro-mechanically operated valves. The valves are controlled by an electric current through the solenoid. The TCM high side driver 1 is located inside of the control solenoid valve assembly which has no serviceable parts. The high side driver 1 provides power to the Transmission Control Module pressure control solenoids and shift solenoids. The Diagnostic Trouble Code (DTC) will be set when the TCM detects an internal open or short to ground on the high side driver 1 for 1 s.
