Circuit Description
WARNING: This page is about a different variant/trim than selected.
The transmission control module (TCM) provides voltage to the pressure control solenoid, the shift solenoids, and the torque converter clutch pulse width modulated (TCC PWM) solenoid through 2 separate solid-state devices called high side drivers (HSD) - HSD1 and HSD2. HSD1 provides electrical power to the pressure control solenoid. HSD2 provides power to the shift solenoids and the TCC PWM solenoid. A normal function of the TCM is to run tests on each driver to ensure that it is functioning properly.
When the TCM detects an open or a short to ground on HSD2, DTC P1833 sets. DTC P1833 is a type A DTC.
