CIRCUIT DESCRIPTION:PCS2 is a Pressure Proportional to Current (PPC) solenoid used to control oncoming and off-going and holding pressure to any one of five clutches. The TCM sends control current to PCS2 from High Side Driver 2 (HSD2) via wire 171. HSD2 is continuously on unless the TCM detects a fault condition. The TCM regulates the amount of current to PCS2 by switching the low side driver ON and OFF. Wire 136 completes the circuit between PCS2 and its low side driver. DTC P0964 indicates that the TCM processor has detected an open condition in the electrical circuit. The open...

CIRCUIT DESCRIPTION:PCS3 is a Pressure Proportional to Current (PPC) solenoid used to control oncoming and off-going and holding pressure to any one of five clutches. The TCM sends control current to PCS3 from High Side Driver 3 (HSD3) via wire 131. HSD3 is continuously on unless the TCM detects a fault condition. The TCM regulates the amount of current to PCS3 by switching the low side driver ON and OFF. Wire 137 completes the circuit between PCS3 and its low side driver. DTC P0968 indicates that the TCM processor has detected an open condition in the electrical circuit. The open...

CIRCUIT DESCRIPTION:HSD3 supplies battery voltage to PCS3 via wire 131. HSD3 is continuously on during normal operation except during brief circuit tests. The TCM regulates control current to the solenoid by switching the appropriate low side driver on and off. DTC P0970 indicates the TCM has detected that the solenoid connected to the HSD3 is inactive with a supply voltage in the HSD3 circuit lower than a calibrated voltage. DTC P0970 indicates a shirt-to-ground has occurred in the high side wiring attached to HSD3 (wire 131). ACTION TAKEN WHEN THE DTC SETS:When DTC P0970 is active, the following conditions occur:1....
