CONDITION

01 14 04 February 19, 2014 2028625 Supersedes Technical Bulletin V011327 dated August 13, 2013 to include additional model year and update the software levels, SVM code and part number.

Update Programming ECM to Eliminate DTC 03366 Stored in Brake Electronics Fault Memory

Customers may complain of a Brake Warning Light ON in the instrument cluster.

Tip:

This software update is designed to re-program both the ECM and TCM with new software. The re-programming itself should carry out the updates without technician intervention. Please ensure both ECM and TCM software has been updated after the flash is completed.

The following fault code may be stored in the Brake Electronics Fault Memory:

DIAGNOSTIC TROUBLE CODES

DTC	Description
03366	Brake electronics - (03366) Vacuum Sensor -G608 Implausible Signal

NOTE: DO NOT diagnose or replace components due to 03366 fault before performing the update function as explained in this bulletin.

TECHNICAL BACKGROUND

If vehicle is equipped with an automatic transmission, TCM must be reprogrammed along with the ECM. If vehicle is equipped with a manual transmission, TCM reprogramming is not possible.

This condition occurs due to an incorrect sampling rate between the ECM and the G608 Vacuum Sensor. The symptom as described will store the fault 03366 in the Brake Electronics Fault Memory. This fault will cause the Brake Warning Light to display in the instrument cluster

DO NOT replace any parts for this condition.

The condition as described does not affect vehicle braking performance or operation.

PRODUCTION SOLUTION

Improved ECM software was introduced in production.

SERVICE

Update-Programming Procedure

Tip:

To Update-Programming using SVM, review and follow instructions in Technical Bulletin Instance 2014603 "Software Version Management".

The SVM Process must be completed in its entirety so the database receives the update confirmation response. A warranty claim may not be reimbursed if there is no confirmation response to support the claim.

NOTE: Prior to launching the VAS-PC and ODIS service diagnostic applications and starting control module update process, confirm tester screen saver and power settings in accordance with Special Tools and Equipment - Service Information Circular # VVT-12-02. Failure to do so may result in the tester entering power save mode during data transfer, and subsequent control module failure.

When using a VAS 6150/5051B or VAS 5052A tester in conjunction with a VAS 5054A wireless transmitter head for a flash procedure, please connect a USB cable between the transmitter head and the tester. Failure to do so may lead to errors during the flash procedure.

VAS tools must only be used with their power adapters plugged in. Under no circumstances should they be used on battery power alone during the programming procedure.

Critical Warning: The Midtronics Battery Charger must be connected to the vehicle battery for the duration of the programming, to ensure the battery state of charge remains above 12.5 volts during the update process. If the battery drops below 12.5 volts, the programming could fail which may result in damage to the control module. Control modules damaged by inadequate voltage will not be covered under the warranty policy. The technician should verify the vehicle voltage prior to starting the update process, and should monitor the voltage for the duration of the update.

Update the Engine Control Module using the SVM Unit code as listed in the table below:

SOFTWARE VERSION MANAGEMENT

Model	Engine	Old Software Part No.	Old Software Version	New Software Part No.	New Software Version (or higher)	SVM Unit Code
Jetta (A6)	2.0L MPI (CBPA)	All	All	06G 906 055 AD	1302	3989
Jetta (A6)	2.0L MPI (CBPA)	All	All	06G 906 055 AE	1302	3989

Tip:

Upon completion of software update, verify Cruise Control function (if originally equipped) is activated via GFF Function Test Plan 01 - Activate/Deactivate Cruise Control System.

Update the Transmission Control Module using the SVM Unit code as listed in the table below:

SOFTWARE VERSION MANAGEMENT

Model	Engine	Old TCM Software Part No.	Old TCM Software Version	New TCM Software Part No.	New TCM Software Version (or higher)	SVM Unit Code
Jetta (A6)	2.0L MPI (CBPA)	09G927750LE	1791 1975	09G927750LE	2330	3801
Jetta (A6)	2.0L MPI (CBPA)	09G927750LE	2040 2174	09G927750LE	2329	3801

The procedure can be found in GFF under Functions/Component Selection, Software Version Management, Adapting Software.

Tip:

Upon completion of software update, verify Cruise Control function (if originally equipped) is activated via GFF Function Test Plan 01 - Activate/Deactivate Cruise Control System.

WARNING: Radiator Fan(s) may cycle ON high speed during the Update Process! There is a risk that personal injury may result if contact is made with spinning fan blades.

Keep hands and all objects away from Radiator Fan(s) during Update Process!

Tip:

Ensure attached ECM/TCM Tuning Form has been completed and signed by customer as required in SVM Technical Bulletin Instance 2014603 .
