Pinpoint Test F : DTCS P0C2A:00, P0C2C:00, P0C2D:00, P0C2E:00, P2796:00

WARNING: This page is about a different car, the 2015 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

F1 RETRIEVE AND RECORD ALL DTCS

Using the diagnostic scan tool, retrieve all DTCs.

Are DTCs P0C2A:00, P0C2C:00, P0C2D:00, P0C2E:00, P2796:00 present?

Yes	For DTC P2796, GO to F7 For all other DTCs, GO to F2

No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or terminal issues.

F2 CHECK THE TRANSMISSION FLUID AUXILIARY PUMP POWER CIRCUITS

F10 CHECK THE TRANSMISSION FLUID AUXILIARY PUMP DUTY CYCLE OPERATION
- Connect PCM C1232E .
- Connect Transmission Fluid Auxiliary Pump C1717 .
- Connect the diagnostic tool.
- Ignition ON.
- Using a diagnostic scan tool, COMMAND the transmission fluid auxiliary pump ON using, TRANS_PMP_CMD and set to a duty cycle of 70%.
- MONITOR the PIDs, TRANS_PMP_MEAS.
Does TRANS_PMP_MEAS quickly return to 44% to 51% after the command percentage changes?

Yes The transmission fluid auxiliary pump is operating correctly at this time.

No INSTALL a new transmission fluid auxiliary pump. Refer to: Transmission Fluid Auxiliary Pump .
