Control module function (coding/programming): Diagnosis: Notes

Faults are only entered within the voltage range 9.0 V to 15.0 V. The specified voltage corresponds to the measured value on the measuring leads of the vehicle electrical system battery. In the event of an open circuit in the measuring leads, the vehicle electrical system control module receives an 'implausible signal', which is stored in the fault memory. Only the fault 'implausible signal' is stored in the fault memory; no other faults are stored. This approach is intended to speed up fault localization. The exception to this approach is the 'Rain/light sensor' fault, which is also stored when the voltage is less than 9.0 V.
