Diagnostic mode 2: Check operating conditions

Function

This diagnostic mode displays the operating conditions at which an emission-relevant malfunction was detected and stored by the Engine Control Module (ECM) or Transmission Control Module (TCM).

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 2: Check operating conditions."
Select the desired operating condition "PID XX".

NOTE:

The following list only serves as an overview.
The operating conditions are sorted by the PID (parameter-identifications).
Bank 1 = Cylinder bank 1, in direction of travel, right.
Bank 2 = Cylinder bank 2, in direction of travel, left.
