Diagnostic Mode 01 - Read Current System Data

Special tools and workshop equipment required

Scan Tool

Function

Diagnostic Mode 01 makes it possible to access current emissions-related measured values and diagnostic data. The original measured values (no replacement values), input and output data and system status information are displayed using Diagnostic Mode 1.

Prerequisite

Coolant temperature must be at least 80° C → PID 5, Coolant temperature.

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 1: Checking measured values."

-- Select the 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.

PID	Diagnostic mode	Module number 10 (bank 1) and 11 (bank 2) Engine electronics	Module number 1A Transmission Electronics
01:	Monitoring status since erasing DTC memory	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
