2.0L - Generic Scan Tool - Engine Code(s): Bpy: Diagnosis Volkswagen Eos I

GENERIC SCAN TOOL MANUAL CONTENTS

"GST" is an acronym for Generic Scan Tool Information.

Included in the contents of this GST manual is a summary table of the vehicle specific OBD II Emission Related Engine and Transmission DTCs. This table contains all necessary Malfunction Criteria, Threshold Values, Secondary Parameters, Enabling Conditions, Monitoring Time Length, Frequency of Checks, and MIL Illumination to accurately monitor and diagnose the Engine Emissions and Transmission and perform all functions required to run Modes 01 through 09 with a hand held scan tool. For a further description of the monitor strategies, a document reference has been provided throughout this GST manual to the applicable OBD System Strategy document.

This GST information also contains the step by step pin point test procedures to accurately diagnose the suspected component or system once a DTC has been set. All references to repair procedures and wiring diagrams will be found within the diagnostic test procedure.

DIAGNOSTIC MODE, SELECTING

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, generate readiness codes, and select the various PIDs and Test-IDs used within the modes to monitor the engine, and emission related component parameters.

The following table provides a link to all diagnostic modes that monitor all components and systems which influence the emission quality.

Note. 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 - READ CURRENT SYSTEM DATA

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.

Depending on scan tool and protocol used, the information displayed in diagnostic mode 01 may be referred to by different names such as Test-ID (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.

Test requirement

1. Coolant temperature at least 80° C.

Procedure

Connect the scan tool.

Start the engine and run at idle.

Select "Diagnostic Mode 1: Obtain data.".

From the following table, select the desired the "PID" that is to be monitored, e.g. "PID 05-Coolant temperature".

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

Switch the ignition off.

End of diagnosis.

DIAGNOSTIC MODE 02 - READ OPERATING CONDITIONS

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.

Depending on scan tool and protocol used, the information displayed in diagnostic mode 02 may be referred to by different names such as Test-ID (CID), 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.

Switch the ignition off.

End of diagnosis.

DIAGNOSTIC MODE 03 - READ DTC MEMORY

Diagnostic Mode 03 makes it possible to read emissions-related faults (confirmed DTCs: faults which have activated the MIL) in the ECM and in the TCM.

When the Engine Control Module (ECM) -- recognizes an emission related fault it turns on the Malfunction Indicator Lamp (MIL) -- or if a Electronic Throttle Malfunction is recognized, the Engine Control Module (ECM) -- turns on the Electronic Power Control (EPC) Warning Lamp -- which are both located in the instrument cluster.

The DTC's are sorted by SAE code with the DTC tables consisting of a 5-digit alpha-numeric value.

Depending on scan tool and protocol used, the information displayed in diagnostic mode 03 may be referred to by different names such as Test-ID (CID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.

The following tables provide a breakdown and explanation of the DTC code.

P-Codes

U-Codes

DIAGNOSTIC MODE 04 - ERASE DTC MEMORY

Diagnostic Mode 04 makes it possible to erase the DTC memory and to reset all emissions-related diagnostic data. In that way, all faults in the DTC memory in the ECM and TCM are erased. The adaptation values may also be reset.

Emissions-related diagnostic data includes (as applicable)

1. MIL Status
2. Number of DTCs
3. Readiness Bits
4. Confirmed DTCs
5. Pending DTCs
6. DTC that belongs to freeze frame
7. Freeze frame data
8. Test results of specific diagnostic functions
9. Distance driven with "MIL ON"
10. Number of Warm-Up Cycles after erasing the DTC memory
11. Distance driven after erasing the DTC memory
12. Misfire counter

Depending on scan tool and protocol used, the information displayed in diagnostic mode 04 may be referred to by different names such as Test-ID (CID), 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.

Switch the ignition on.

Select "Diagnostic Mode 03: Interrogating fault memory ".

Then select "Mode 4: Reset/delete diagnostic data".

The scan tool will display: "Diagnostic data are being erased".

Switch the ignition off.

End of diagnosis.

DIAGNOSTIC MODE 06 - READ TEST RESULTS FOR SPECIFIC DIAGNOSTIC FUNCTIONS

Diagnostic Mode 06 makes it possible to retrieve test results for special components and systems which are continuously or not continuously monitored. If the diagnosis of a system is complete, the diagnostic result and the corresponding thresholds are saved and displayed in mode 06. This data remains saved (even with the ignition off) until either new diagnostic results become available or the DTC memory is erased.

The min & max values for each individual test in Mode 06 represent the min & max operating values for a properly operating system. This data is provided to the individual aftermarket scan tool companies for development of their scan tool. Depending on the scan tool being used, the min & max values shown may vary, or be rounded up or down to the nearest decimal point depending on the aftermarket scan tool company's development process. e.g.

Depending on the scan tool and protocol used, the information displayed in Diagnostic Mode 06 may be referred to by different names such as Test-ID (CID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and may be referenced by only a number.

Test requirements

2. No DTCs stored in the DTC memory.
3. Coolant temperature at least 80° C.
