Diagnostic mode 1: Check measured values

Function

In this diagnostic mode, all emissions-relevant measured values are displayed.

Requirement

Coolant temperature must be at least 80 ° C. Refer to PID 5, Coolant temperature.

Work procedure

start engine and let run at idle.

NOTE:

The specified values for the measuring values can be found under the respective component- and function tests.
The following list only serves as an overview.
The measuring values are sorted according to the PID (parameter-identifications).
