Upon further investigation the technician may find the following Diagnostic Trouble Codes \(DTCs\) have been set: P0563\-00 \- System Voltage High\(2020 M6 Vehicles equipped with 2.0L I4 Turbo Diesel Engine W/ESS \(Sales Code EBS only\)\). P21CC?00 \- Reductant Control Module Supply Voltage High\(2020 M6 Vehicles equipped with \(Sales Code EBS only\)\). P1515\-00 \- Plausibility Check R1 Stuck Closed Or Vsensing Short To Battery In Engine Running\(2019 M6 only\). B25C9 \- Driver Door Ajar Switch 2 Stuck Closed \(Module, Powertrain Control \(PCM\)\). Stored DTC only, this update isnotfor active fault.If B25C9 is an active fault normal diagnostic must be performed. This software update will not correct active DTC. P26E4\-64 \- Starter Control 2 Circuit\-Signal Plausibility Failure. In addition, customers or technicians may comment on one or more of the following:Engine Stop/Start \(ESS\) not functioning properly\(2020 M6 Vehicles equipped with \(Sales Code EBS only\). Four wheel drive not functioning\(2020 M6 Vehicles equipped with \(Sales Code EBS only\). No start condition if the vehicle has both P1515\-00 and P26E4\-64 DTCs\(2019 M6 only\).
