Read and follow the basic instructions. Including GenBoard/Manual/GroundConnections http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FGroundConnections |

Finally the p259 replacement solved the problem. Almost certainly not following the basic instructions => GND problem => killed p259 chip earlier.
* Instructions must be followed * Harness problem can kill several ECU-s so best to follow instructions (the GND instructions are red on the paper sent with the ECU) before attempting to plug in other ECU |

I didn't get any help for vems wiki and vems.hu,
so i tried several things. Finally the p259 replacement solve the problem. (maybe was gnd problem earlier) |
