Circuit Description
WARNING: This page is about a different variant/trim than selected.
The transmission control module (TCM) provides voltage to the main modulation (MAIN MOD), torque converter clutch (TCC) and pressure control solenoid 1 (PCS1) through a separate solid state device called high side driver 1 (HDS1). HSD1 is continuously ON during normal operation, except during a brief circuit test. The TCM regulates control current to the solenoids by switching the appropriate low side driver ON and OFF.
DTC P0658 is a type A DTC.
