Diagnostic mode 1: Check measured values
Requirement
- Coolant temperature must be at least 80° C. Refer to PID 5, Coolant temperature.
Work sequence
- Connect diagnostic tester. Refer to Diagnostic tester, connecting
- Depending on 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 desired measured values "PID XX".
NOTE:
- The specified values for the respective measuring values can be found at 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).
- Bank 1 = Cylinder bank 1, in direction of travel, right
- Bank 2 = Cylinder bank 2, in direction of travel, left
