Functionality associated with the RCM may be missing. Electronic Parking Brake was unable to release due to fault. Electronic Parking Brake faulted during release && (nonterminal == FALSE) Electronic Parking Brake release in progress will be stopped due to the fault, caliper may not have fully released Alert Manager encountered an internal processing error. Debug information for 100ms task errors. The communication link between Electronic Parking Brake and Electronic Parking Brake Monitor has encountered an error. Debug information for 1000ms task errors. Motor current was lower than expected Motor current measurement, with calibration offset subtracted, was lower than 0.25 amps Caliper could be disconnected or the harness is damaged. One or more of the expected CAN messages from SCCM were not received.
