Diagnostic Mode 02: Obtain operating conditions

Diagnostic Mode 02 is used to monitor the operating conditions under which the Motronic Engine Control Module (ECM) J220 has detected and stored an emissions related DTC.

Depending on scan tool and protocol used, the information displayed in diagnostic mode 02 may be referred to by different names such as OBDMID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.

Procedure

Connect the scan tool.
Start the engine and run at idle.

NOTE:

If the engine does not start, crank the engine using starter for at least 5 seconds, do not switch the ignition off afterward under any circumstances.

Select "Diagnostic Mode 2: Obtain operating conditions.".
From the following table, select the desired the "PID" , e.g. "PID 05-Coolant temperature" that is to be monitored.

The current values of the component or system that is being monitored will be displayed on the scan tool screen.

PID	Component or System
02:	DTC which triggered the current reception of all control module information
03:	Condition of fuel system
04:	Calculated load condition value
05:	Coolant temperature
06:	Short term gasoline-air ratio bank 1
07:	Gasoline-air ratio bank 1
12:	Engine rotations per minute (RPM)
13:	Vehicle speed
14:	Ignition timing adjustment at 1. cyl. in direction
15:	Intake air temperature (IAT)
16:	Air stream amount at Mass Air Flow (MAF) sensor
17:	Throttle valve position (absolute)
31:	Time after engine on
35:	Fuel Rail Pressure
46:	Commanded Evaporative Purge
51:	Barometric Pressure
66:	Control module voltage
67:	Absolute Load Value
68:	Commanded Equivalence Ratio
69:	Relative Throttle Position
70:	Ambient air temperature
71:	Absolute Throttle Position B
73:	Accelerator Pedal Position D
74:	Accelerator Pedal Position E
76:	Commanded Throttle Actuator Control

Switch the ignition off.
End of diagnosis.
