Hmm, this
32951 - Control Module for Electronic Parking Brake
C10E2 54 [10001001] - Missing Calibration / Basic Setting
MIL ON - Confirmed - Tested Since Memory Clear
Should be as simple as the opening and closing you were doing last week. Please try this:
Battery charger connected
Parking brake off
Connect to 03-
Basic Settings > [*IDE03331-ENG114972*] Start lining change mode [Go]
Make note of the response. For instance; Not Running versus Finished Correctly
[Stop]
Exit Basic Settings at this point and check Fault Codes to see if there's one for Lining Change Mode. There should be since it would be in the middle of a service action.
Basic Settings > [*IDE03330-ENG114972*] End lining change mode [Go]
Note the response before using [Stop]
Exit the controller, foot on brake pedal, turn the on and back off two full cycles and then re-check for fault codes.
