Summary
Technical Bulletin (Update Programming for Catalyst System Bank Efficiency Below Threshold): This document informs of diagnostic fault codes which state that the Catalyst System Bank Efficiency is Below Threshold this is because the Diagnostic strategy was too sensitive. The production solution for this issue was to stop making the Engine Control Module, and thus it is out of production. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.

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 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 6150X or 6160X 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.
