UPDATE Technical Bulletin
Note:
The supplied software is not associated with stalling or other performance issues. If the
ECM/TCM fault memory contains faults, these faults must be addressed before performing this
UPDATE Technical Bulletin.
If no fault codes are found in the ECM/TCM fault memory: DO NOT diagnose or replace any
components before performing the software update function as explained in this bulletin.

This UPDATE is in effect until removed.
Vehicle must meet all of the following criteria:
•

Procedure is valid only for vehicles that show the 24Y4 code in ElsaWeb, Campaign/Action
Information screen on the day of repair.

•

If the vehicle is sold it must be within the FEDERAL EMISSIONS WARRANTY.

•

Procedure must be performed within the allotted time frame stated in this UPDATE.

•

Procedure must be performed on applicable vehicles in dealer inventory prior to sale.

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, only ECM programming is required.
Current ECM programming may be causing slight hesitation related concerns on vehicles
equipped with 2.0 liter CBPA engines (depending on driving conditions).
The concern as described may be difficult to reproduce.

Production Solution
Improved ECM/TCM software was introduced to address drivability concerns and slight hesitation
complaints.

Service
NOTE:
• ElsaWeb is the only valid inquiry/verification source. Check ElsaWeb on the day this vehicle UPDATE
will be performed to verify vehicle eligibility for the UPDATE. Status must show “open”. Attach an
ElsaWeb printout showing the “open” status to the repair order.

contact Warranty before proceeding further. Another dealer may have recently performed this
UPDATE but not yet entered a claim for it in the system.
• ElsaWeb may also show additional open action(s); if so, inform your customer - this work can be done
while the vehicle is in for this UPDATE.

questions.

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 VAS-PC application and starting control module update process, confirm tester screen
saver and power settings in accordance with ServiceNet=> Workshop Equipment=> VAS Tester=>
Service Information=> 2012=> 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.
