F0 - Data List






The current actual values of all important sensors and signals in the system are displayed through Mode F0. The displayed actual values must then be compared with the specifications listed in the Checking instructions. From these the trouble can be clearly diagnosed. In the Quick Check list, all the test steps are summarized, so that (for example), after a mechanical/hydraulic problem, the electronic functions can also be quickly checked.

NOTE: Values shown in the chart are for example only. See F0: DATA LIST QUICK CHECK for actual specifications.
