Attention:
Please inform the customer that this condition does not cause any driveability, reliability or durability concern with their vehicle.
Supercede:
This bulletin is being revised to add the 2008 HUMMER H2. Please discard Corporate Bulletin Number 08-06-04-045 (Section 06 - Engine/Propulsion
System).
Condition
Some customers may comment that the MIL/SES light is illuminated.
Upon further investigation, technicians may find the Diagnostic Trouble Code(s) (DTCs) stored as shown above.
Cause
This condition may be caused by the use of gasoline that exceeds the 80 Parts Per Million (PPM) maximum U.S. Federal guideline for sulfur content, but
is within the 80 PPM - 450 PPM sulfur content special exemption allowed for small U.S. refineries and/or the greater than 80 PPM sulfur content fuels
found in other parts of the world. In Canada, federal regulations limit the sulphur content for gasoline sold in Canada to 80 Parts Per Million (PPM)
maximum with no exemptions.
Correction
Important:
Verify that the 12-volt battery has a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only
use approved Midtronics PSC-550 charger/maintainer or equivalent to maintain proper battery voltage during programming. The J2534 MDI
will reprogram the modules in less time than the Tech 2(R) scan tool.
A revised engine calibration has been developed to address this condition, which is titled "New calibration with diagnostic enhancements for
DTCs P1133 and P1153". Technicians are to reprogram the Engine Control Module (ECM) using the Service Programming System (SPS) with the
latest software available on TIS2WEB. Refer to the Engine Control Module Programming and Setup (Gasoline Engines) and Service
Programming System (SPS) procedures in SI for more information. As always make sure your Tech 2(R) is updated with the latest software
version.
