Diagnostic Mode 02 - Read Operating Conditions

Function 

When an emissions-related fault (pending DTC, visible in mode 07) is first detected, operating conditions are stored. Mode 02 makes it possible to access this freeze frame data as soon as this fault is shown in mode 03. Each control module only shows freeze frame data for one fault via mode 02. Therefore, there are two priority levels. If there is a malfunction with higher priority, the freeze frame data is overwritten.

-- Fault with higher priority: Misfire malfunction or fuel trim malfunction.

-- Fault with normal priority: All other emissions-related faults.

Procedure 

-- Connect diagnostic tester.

-- 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".

PID	Diagnostic mode			Module number 10 (bank 1) and 11 (bank 2) 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	---
05:	Coolant temperature			X	X
11:	Intake manifold pressure			X	---
12:	Engine rotations per minute			X	X
13:	Vehicle speed			X	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 P0XXX DIAGNOSTIC TROUBLE CODES .
• SAE P1xxx-DTCs SAE P1XXX DIAGNOSTIC TROUBLE CODES .
• SAE P2xxx-DTCs SAE P2XXX DIAGNOSTIC TROUBLE CODES .
• SAE P3xxx-DTCs SAE P3XXX DIAGNOSTIC TROUBLE CODES .
• SAE U0xxx-DTCs SAE U0XXX DIAGNOSTIC TROUBLE CODES .

-- End diagnosis and switch ignition off.
