This diagnostic checks for the range of the hydraulic pump driver feedback signal provided by the Smart Drive Unit (SDU) to the Transmission Control Module (TCM). The SDU unit drives the hydraulic pump by actuating a PWM command signal received from the TCM. The normal range of the hydraulic pump driver feedback signal is up to 30% of the power supply voltage.
