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 control module for Diesel-Direct fuel injection system or the 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 desired operating condition "PID XX".

NOTE:

The following list only serves as an overview.
The operating conditions are sorted by the PID (parameter-identifications).

PID	Diagnostic mode	Module number 10 Engine Electronics	Module number 1A Transmission Electronics
02:	DTC which triggered the current reception of all control module information	X	X
04:	Calculated load condition value	X	X
05:	Coolant temperature	X	X
11:	Intake manifold pressure	X	---
12:	Engine rotations per minute (RPM)	X	X
13:	Vehicle speed	X	X
14:	Valve timing adjustment at 1. cyl. to "advance"	X	---
15:	Intake Air Temperature (IAT)	X	---
16:	Air flow quantity at Mass Air Flow (MAF) sensor	X	---
17:	Pedal value sensor (%)	X	X

If DTCs are displayed in "PID 02":

Repair stored malfunctions according to DTC table:

SAE P0xxx-DTCs.
SAE P1xxx-DTCs.
SAE P2xxx-DTCs.

NOTE:

The DTC table is sorted by SAE code.
"Emission"-relevant malfunctions are indicated in the instrument cluster via the exhaust Malfunction Indicator Lamp (MIL).
Erase DTC memory after repairing malfunction. Refer to Diagnostic mode 4: Reset/erase diagnostic data .

End diagnosis and switch ignition off.
