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
- Connect diagnostic tester. Refer to Diagnostic tester, connecting
- Depending on the desired operating condition: switch on ignition
or
start engine and let run at idle.
- Under address word 33, select "Diagnostic mode 1: Check measured values."
- Select the desired measured value(s) "PID XX".
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).
