5R44E/5R55E EPC In Bench Mode

5R44E/5R55E EPC in BENCH MODE
The BENCH MODE is also used to test the functionality of the transmission's electronic pressure control. During BENCH MODE, the EPC solenoid can ramp in increments of 15 PSI from zero to 90 PSI and 90 to zero PSI.

The OSC functions for the parameter EPC allow the technician to choose the following operations.
^ EPC - Activates EPC to selected values.
^ [00] - sets EPC pressure to 00 PSI.
^ [15] - sets EPC pressure to 15 PSI.
^ [30] - sets EPC pressure to 30 PSI.
^ [45] - sets EPC pressure to 45 PSI.
^ [60] - sets EPC pressure to 60 PSI.
^ [75] - sets EPC pressure to 75 PSI.
^ [90] - sets EPC pressure to 90 PSI.

OSC "EPC" BENCH MODE Operates ONLY when:
^ VSS and digital TR sensor are operational.
^ No VSS and digital TR sensor DTCs.
^ Transmission range selector lever in P.
^ Pressure gauge installed.
^ Key ON.
^ Engine ON.
^ Engine rpm at 1500.
