CIRCUIT DESCRIPTION:PCPS1 is a Pressure Proportional to Current (PPC) solenoid used to control oncoming, off-going and holding pressure to any one of five clutches. The TCM sends control current to PCS1 from High Side Driver 1 (HSD1) via wire 111. HSD1 is continuously on unless the TCM detects a fault condition. The TCM regulates the amount of current to PCS1 by switching the low side driver on and off. Wire 155 completes the circuit between PCS1 and its low side driver. DTC P2730 indicates that the TCM processor has detected a short-to-battery condition in the low side of the electrical...

CIRCUIT DESCRIPTION:The TCC PCS is a Pressure Proportional to Current (PPC) solenoid used to control the TCC apply and release. The TCM sends control current to solenoid TCC from High Side Driver 1 (HSD1) via wire 111. HSD1 is continuously on unless the TCM detects a fault condition. The TCM regulates the amount of current to the TCC by switching the low side driver on and off. Wire 178 completes the circuit between the TCC and its low side driver. DTC P2761 indicates that the TCM processor has detected an open condition in the electrical circuit. The open condition may...

CIRCUIT DESCRIPTION:Clutch Life Monitor is part of OEM 5th Generation Prognostics functionality. When enabled in the TCM, prognostic logic determines transmission health with clutch adaptive volumes. When the transmission is new the TCM stores the initial clutch volumes. Throughout the life of the transmission these initial volumes are compared to the current volumes and are correlated to free running clearance, allowing transmission life expectancy to be determined. If the TCM determines that clutch volumes are out of range for a specific clutch, a J1939 message is sent to a dash mounted SERVICE TRANS indicator lamp informing the driver the transmission...
