RE: Mokka B1517 Problem - xander20005 - 18-12-2018 bring the car and I fix. check the battery, generator, ground... RE: Mokka B1517 Problem - Koira - 08-04-2019 Any progress on this issue? Have a similar case here. I tried measuring ground and supply from bcm - all good, bcm show battery voltage same as on battery terminals, after 10 seconds B1517 5A is flagged. Battery sensor has B+ and LIN to BCM connection ok. Only thing that I have discovered is that in ECU data show malfunction state for generator low voltage test result. As found on some repair documents, measured resistance between generator L-terminal and ground is ~300ohm opposed to suggested infinite resistance. |
