If the fault memory cannot be erased, it is necessary to check whether the coding corresponds to the vehicle equipment.

A plus sign (+) present in the line or not present indicates a loose contact. A counter is started when the symbol changes from not present to present. This counter indicates how often the change took place from present to not present.

When a fault is identified, a fault start clock is started. The fault start clock shows the time in hours, minutes and seconds that has passed since the fault first occurred.
