Supersedes T.B Repair Group 01 No. 03-04 dated Apr. 17, 2002 due to incorrect date only
Condition
ECM requires "Update - Programming" (flashing) to correct following DTCS:
In addition, "Update - Programming" (flashing) where the following groups of 3 misfire DTCs
(cylinders 1, 2 and 3) on Bank 1 and / or
(cylinders 4, 5 and 6) on Bank 2 are stored.
For cylinder misfire DTCs stored on 1 or 2 cylinders only, reflash is not indicated, additional diagnosis will be required.
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 Audi of America, Inc..
If you encounter a vehicle with a "Tuned" ECM, prior to performing the 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 tuning of the ECM (including adverse emissions consequences) will not be covered by Audi 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 his written consent (see Control Module Tuning form) to the flashing procedure.
Tool requirements
^ VAS 5051 or VAS 5052 with Basis CD A.05.15 and the Brand CD A.05.0 (or later).
^ "Update - Programming" (flashing) CD "KM01" (indicated on CD).
Additional copies of "Update - Programming" (flashing) CD (Item no: A0050012588) may be ordered from the Audi Technical Literature Ordering Center.
Vehicle requirements
^ Battery MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM failure).
^ VAS 5051: connected to vehicle (using K-lead adapter VAS6017A) and to 110V AC Power supply at all times during procedure.
^ VAS 5052: connected to vehicle (using K-lead adapter VAS 6017A) with battery voltage requirements met.
^ Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.
^ No stored DTCs, print and 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.
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 the level indicated on Flashing CD:
^ "Update - Programming" (arrow) will not appear.
Note:
The "Update - Programming" function is only available when the inserted flash 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) will appear.
PRIOR to performing procedure to
"Update - Programming" (flash) the ECM:
Note:
Failure to erase ALL fault memories may cause "Update - Programming" (flashing) procedure to fail!
^ ALL fault memories must be interrogated and erased.
- Select Diagnosis function 06 "End output".
- Select Diagnosis function 00 "Collection services".
- Select "Check DTC memory - complete system" which will interrogate all fault memories.
- Print all DTCs.
- Erase ALL fault memories.
Once ALL fault memories have been erased:
- Select vehicle system "01 - Engine electronics".
- Select "Update - Programming" option at the bottom of the screen (arrow).
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:
^ New program version and approximate timing for update is shown on the VAS 5051/5052 screen.
- By selecting the --> button, programming procedure begins.
<-- Similar screen appears.
^ The previous data in the ECM is erased and the new data is being transferred to the module from the flash CD.
Note:
Approx. flash time is 17-19 minutes.
NOTE:
If, during the "Update - Programming"; a fault message is displayed:
- 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.
^ Old ECM Part No. and software level are still displayed at (arrows).
Note:
New ECM Part No. and software level are 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 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 be 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, confirm by selecting the --> button.
Note:
Erase fault memories takes approx. 15 minutes.
Once the fault memories have been erased:
^ Similar screen appears.
^ Old software level still appears at (arrow).
^ Function ended appears at bottom of screen.
- You must now select the ~ button to access and view the ECM update data.
^ Similar screen appears.
^ New ECM Part No. 8E0 909 559E will appear
^ Update version software level 0003 will appear at (arrow).
- Print the ECM screen to verify ECM update software level.
- Attach print to vehicle Repair Order.
^ Flash CD can now be removed from VAS 5051 or VAS 5052 Diagnostic tool.
- 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.
To set readiness code:
^ Use VAS 5051 or VAS 5052 and Self Diagnosis, along with the attached Quick Reference "How to set Readiness Code".
Note:
VAS5O51 Guided Fault Finding (GFF) may also be used to set readiness code.
