Hellooo



It's jaguar XF 2013 portfolio

The problem is that there is plenty of warnings on the dash regarding DSC parking brake EBP battery not charging and sometimes the car doesn't want to start ....so from what I read it can be BCM that I already checked and there is no water damage or corrosion on both central and rear junction boxes....washer system work ...car lock and unlock ...key less working ....all fuses been checked and ground cables rechecked and the cable on right side under washer tank as well checked .....parking brake doesn't work as well with all the warning ......on the diagnostic plenty of issues most of them regarding list communication with different modules .....and on this time car doesn't want to start .. after removing battery and charged in in full ...after clear all fault codes with launch diagnistic ...car start and the only one fault is regarding transmision box module and fault cide for oarking brake ....on this time car start and drive but dash still warning fir press brake pedal ir simmilar ....after leaving the car fir a day it starts agaib with lost communication with modules and cant start and need disconnecting battery again ......battery is new ...next days will replace alternator as well .... charging is 15.8 on cold and 14.8 on warm .....

I have SSD (but never used it ) and 100a 12v psu power supply
