Update Programming MIL On DTCs P0420 And P0430 Stored In ECM Fault Memory

One or more of the following fault codes may be stored in the ECM Fault Memory:

DIAGNOSTIC TROUBLE CODES

DTC	Description
P0420	Catalyst System Efficiency Below Threshold, Bank 1
P0430	Catalyst System Efficiency Below Threshold, Bank 2

NOTE: DO NOT diagnose or replace components due to P0420 or P0430 faults before performing the update function as explained in this bulletin.

DO NOT diagnose or replace catalytic converter or other components before performing the update function as explained in this bulletin.

TECHNICAL BACKGROUND

Monitoring strategy for the catalyst monitoring is too sensitive causing P0420 and or P0430 faults to incorrectly set in the engine control module.

Updated programming of the ECM software is based on most recent engineering experiences and makes this knowledge available for the monitoring strategies.

PRODUCTION SOLUTION

No improvements were made in the vehicle production period.

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 Special Tools and Equipment - Service Information Circular # VSE-08-18. 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.

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
2007 Eos	3.2L (BUB)	022 906 032 CF	All	022 906 032 CF	9971	3550
2008 Eos	3.2L (CBRA)	022 906 032LF	All	022 906 032LF	9189	3550
2008 R32	3.2L (CBRA)	022 906 032 KR	All	022 906 032 KR	1319	3550

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

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: 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 or action is carried out that is not explicitly stated in the Technical Bulletin.

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