Transit BJ 2008 rarely starts. When pushing immediately and running calmly. Crankshaft sensor renewed, Delphi program does not read out any error. Sometimes during the key turn, the entire power grid breaks away. At the re-turning organ it returns. Then comes error “Communication with immobilizer control unit failed” At the start process…. – Engine speed 216 U/min. – 10,6 Volt. – Relay start process = Disactivated – Synchronization camswele crankshaft= yes – Request fuel injection = 0.00 – fuel pulse width = 0.0 ms – fuel distribution requirement = 0 Mpa What could this indicate? Should I read out other values? On Saturday I try to get the 2 keys.
