Volvo XC90 CEM problem - pimpammm - 28-03-2024 Hi guys, I have volvo xc90, 2005y. Car cannot start, no cranck, there is a fault code in CEM - 6C48 transponder type faulty signal. I check immo parameters: Battery in the car was dead for a while and after that I couldnt start the car. I dont know if it needs some synchro cem-ecu, or keys need to be added to cem... If someone had this problem before, or know what to do that would be grate. I've read CEM module M30855FW and 93LC86C, CEM number 30728539. ECU is edc15c11 with eeprom 5P08C3, I also took a photo of ABS id. Maybe someone can help me with this problem. Thanks
