Diagnostic Modes 01 - 09

Diagnostic Mode 01 - Read Current System Data

The information provided in Modes 01 through 09 displays the various levels of emission related data that may be monitored, as well as the ability to retrieve and read stored DTC trouble codes, erase stored DTC trouble codes, generate readiness codes, and select the various PIDs and Test-IDs used within the modes to monitor the engine, and emission related component parameters.

• Depending on scan tool and protocol used, the information in diagnostic mode 01 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), or On-Board Diagnostic Monitor Identifier (OBDMID).

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".

• 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

• Measuring values of Engine Control Module (ECM) are displayed under "10 - Engine electronics" and measuring values of Transmission Control Module (TCM) are displayed under "1A - Transmission electronics".





* PIDs that are not relevant are not listed.

- End diagnosis and switch ignition off.
