SUBJECT

Update Programming (Flashing) Engine Control Module (ECM)

CONDITION

ECM requires "Update - Programming" to correct Diagnostic Trouble Code (DTC) P0300 and any of the following DTCs - P0301, P0302, P0303, P0304.

For ECM Part Nos:

SERVICE

CAUTION: The following "Update - Programming" (flashing) process may overwrite any "TUNED" ECM programming.

A "TUNED" ECM is described as any ECM altered so as to perform outside the normal parameters and specifications approved by Volkswagen of America, Inc..

If you encounter a vehicle with a "Tuned" ECM prior to performing the "Update - programming" (flashing) procedure.

Your Dealership should place the vehicle owner on notice in writing. that their ECM was found to have been tuned and that any damage caused by the tunning of the ECM (including any adverse emissions consequences) will not be covered by volkaswagen of america, Inc. warranties.
For any repair requested by the owner under warranty or outside warranty that requires flashing, which will automatically wipe out the "Tuning" program, your Dealership should advise the owner of the above and get Owner's written consent (see attached Control Module Tuning form) to the flashing procedure.

TOOL REQUIREMENTS

VAS 5051 or 5052 (with Basis CD V.05.10 and the Brand CD V.05.35 or higher) with old diagnosis logs erased prior to start.
"Update - Programming" (flashing) CD W42JETGF18UPDATECD01

NOTE: Additional copies of the "Update - Programming" CD (Literature Number W42JETGF18UPDATECD01) may be ordered from the Volkswagen Technical Literature Ordering Center at vw.ddsltd.com, or by calling 1-800-544-8021 from 8:00 a.m. to 8:00 p.m. EST Monday through Friday. This number can be dialed in both the United States and Canada.

VEHICLE REQUIREMENTS

Battery MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM failure) (it is advised to use an approved battery charger to maintain battery voltage).
VAS 5051: connected to vehicle and to 110V AC Power supply at all times during procedure.
VAS 5052: connected to vehicle with battery voltage requirements met.
Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.
No Stored DTC's, erase any stored DTCs.

CAUTION: Non-observance of the following points may lead to ECM failure!

VAS 5051 or 5052 must always be connected to the approved power supply at the approved voltages. Under no circumstances should the power supply be interrupted or the diagnostic connector unplugged during the flash procedure.

Any appliances with high electromagnetic radiation (i.e. mobile phones) must be switched OFF.

"UPDATE - PROGRAMMING" (FLASHING) PROCEDURE, CHECKING FOR UPDATE MATCH

Switch ignition ON.
Switch VAS 5051/5052 ON and insert flash CD into CD drive as soon as start screen appears.

Fig 1: Testing And Information System Display

NOTE: You must return to the start screen before starting a new (flashing) session, otherwise the flashing CD will not be recognized by the tester.
Select "Vehicle Self Diagnosis" mode.
Select vehicle system "01-Engine electronics".

Program checks software level.

If software level of ECM MATCHES level indicated by Flashing CD:

"Update - Programming" (arrow) will not appear.

Fig 2: Selecting Vehicle System 01-Engine Electronics

NOTE: The "Update - Programming" function is only available when the inserted flashing CD level and current vehicle ECM level are different.

If "Update - Programming" does not appear:

Programming (flashing ECM cannot be performed, continue to diagnose condition.

If software level DOES NOT match the level indicated on Flashing CD:

"Update - Programming" (arrow) appears.

PRIOR TO PERFORMING PROCEDURE TO "UPDATE - PROGRAMMING" (FLASH) THE ECM

ALL fault memories must be interrogated and erased.

NOTE: Failure to erase ALL fault memories may cause "Update - Programming" (flashing) procedure to fail!

Select Diagnosis function 06 "End output".

Fig 3: Selecting Diagnosis Function 06 End Output
Select Diagnosis function 00 "Collection services".
Select "Check DTC memory - complete system". which will interrogate all fault memories.
Erase ALL fault memories.

Once ALL fault memories have been erased:

Select vehicle system "01-Engine electronics".
Select "Update - Programming" option at bottom of screen (arrow).

Fig 4: Selecting Update - Programming Option

CAUTION: Once "Update - Programming" function has been started, switching ignition OFF or disconnecting the diagnostic connector may completely destroy the ECM.

"UPDATE - PROGRAMMING" (FLASHING), PERFORMING

After selecting "Update - Programming" function:

Fig 5: Display After Selecting Update - Programming Function

New program version 0005 for ECM Part No: 06A 906 032 DM.
New program version 0006 for ECM Part Nos: 06A 906 032 GH or 06A 906 032 DL.
Approximate timing for update is shown on the VAS 5051/5052 screen.

By selecting the > button, the programming procedure begins.

Similar screen appears:

Fig 6: Display Programming In Progress

The previous data in the ECM is erased and the new data is being transferred to the module from the flash CD.

NOTE: Approx. flashing time is 17-19 minutes.

NOTE: If, during the "Update - Programming", a fault message is displayed:

Fig 7: Display Diagnosis Bus Faulty

Confirm that VAS 5051 or VAS 5052 diagnostic tool power supply is adequate and that ALL appliances with high electromagnetic radiation (i.e. mobile phones) are switched OFF.
The "Update - Programming" (flashing) process must then be started from the beginning using the "Repeat" button (arrow). DO NOT use the "Cancel" button.

IMPORTANT: On NO occasion should the "Cancel" button be selected.

Once "Update - Programming" (flashing) is complete:

Similar screen appears.

Fig 8: Display Programming Log, Save Result
ECM Part Number and old software level is still displayed at (arrows).

NOTE: New software level is not displayed until process is complete and fault memories have been erased.

Select the "Print", then "Screen" button.
- VAS 5051 will print to printer immediately.
- VAS 5052 will hold the print until process is complete and then you may take the tester to the printer for printing the screen.
Attach print to vehicle Repair Order.
Once "Update - Programming" (flashing) is complete, the control module must be re-initialized.

Select the > button.
- The tester requests you to switch the ignition OFF.

Switch ignition OFF.

IMPORTANT:

Wait at least 20 seconds before switching the ignition back ON (failure to wait at least 20 seconds may damage the ECM).

After waiting 20 seconds:

Switch ignition ON.

After switching ignition ON, the ECM has been re-initialized, however, fault memories must now be erased.

Select the "Continue button"

FAULT MEMORIES, ERASING AFTER "UPDATE - PROGRAMMING" (FLASHING)

Due to the CAN bus system, fault messages will be stored in various Control Modules during programming.

To erase ALL fault memories:

Fig 10: Erase Fault Memories Display

Confirm by selecting the > button.
NOTE: Erase fault memories takes approx. 15 minutes.

Once fault memories have been erased:

Similar screen appears.

Fig 11: DTC Memories Are Erased Display

Updated software level "0005" or "0006" (depending on ECM Part No.) will appear at (arrow).
Flash CD can now be removed from VAS 5051 or VAS 5052 Diagnostic tool.
- Print the ECM screen to verify ECM update software level.
VAS 5051 will print to printer immediately.
VAS 5052 will hold the print until process is complete and then you may take the tester to the printer for printing the screen.

Attach print to vehicle Repair Order.
Select "Go to" then select "Exit".

NOTE: It is not generally necessary to encode the ECM following the "update - Programming" (flashing procedure. However, you must set the readiness code.

Set readiness code.
