Fuel Injector, cylinder 5 - Interruption

Function:
The coil of the fuel injector is supplied on one side with B+ (battery voltage) and on the other with ground via an end stage of the ECM.
For these faults the connection to ground is monitored.

Diagnostic Conditions:
A fault is recognized and stored in memory when the engine speed is above 80 rpm and the battery voltage is between 7.5 Volt and 17 Volt.
