2015 Jeep Cherokee Latitude 3.2L (S EHB) 9-spd (948TE) — 1C4PJMCS0FW595504
C10D0
Start/Stop In-Op
Check Engine Light

SO vehicle has code C10D0-Electronic Park Brake System Failure in ECM that is active. I erased it and code came back. If I cycle the key I can use the park brake switch no problem until ode sets again. I can go into the parking brake module and control the parking brakes. I have put the rear brakes in service mode then taken them out of service mode. Erased codes and code still resets. ECM has latest calibration available from Chrysler. Not really sure what else I could check other than replacing the module. Hoping you guys might have some ideas on what I could test before making that call.

I would try a hard reset first

Did this and now it sets a code for a P057F-14 VOLT BATTERY STATE OF CHARGE PERFORMANCE. This is going to be a fun one.

It is actually normal to set ignore it the MIL should be off and will not effect a inspection. Sometimes if the vehicle sits for a few hours it will go stored and you can erase the code. This is a programming issue from FCA.

It always rests as a active code. The parking brake becomes in-op and start/stop becomes in-op.

How long has the vehicle been allowed to sit with the key off no scantool in it. I've had to let one sit for nearly 24 hours to clear a code when I was still a dealership tech. This is provided there are no EPB codes, there may also be some corrosion in the EPB module/connector just not causing a issue. You can also try to run the assembly check routine in the EPB, place EPB in service mode…

There is one step I would do next for good measure. (Grounds) pin 30 and pin 28 at the control module , voltage drop test while actuating.

I would look for the ground, G923A, in cargo area on the left rear. It looks like its one ground point for a few different things. If it is ok, I would replace the module.

Check module in left rear and look for a green/ crusty connector. There might be a bulletin for this.

I have seen a few Electronic Park Brake modules with (green) in the connectors. Just a thought.
