P0748

Conditions for Setting the DTC
- The Transmission Control Module (TCM) detects that the current of the Pressure Control Solenoid (PCS) is less than 10 mA for 12.5 seconds continuously when the TCM output current is greater than or equal to 60 mA. (The PCS circuit is shorted to ground or open.)
- The TCM detects that the current of the PCS is greater than 1.4A for 0.5 second continuously. (The PCS circuit is shorted to battery.)

Action Taken When the DTC Sets
- TCM will request the illumination of power lamp and store DTC when TCM detects a failure on the first ignition cycle.
- 4th near is held in "D" range.
- 4th gear is held in "2" range.
- 1st gear is held in "L" range.
- No TCC lockup control.
- Full line pressure.

Conditions for Clearing the MIL/Power Lamp/DTC
- The TCM turns off the MIL when no further failures detected for three consecutive ignition cycles.
- The Scan-100 scan tool can clear the DTC from the TCM history.
- The TCM clears the DTC from the TCM history memory after forty consecutive ignition cycles without fault while it detects that the current of the PCS is between 0.01 and 1 .4A for 12.5 seconds continuously.
