Silverado 1500 2WD V8-5.3L VIN Z Flex Fuel (2006)
Service Procedure
The "Required Field Actions" section of the GM Vehicle Inquiry System (GMVIS) must be checked to determine if a specific vehicle requires this
action. If GMVIS indicates that Service Update Bulletin 06162C remains 'open' and ECM reprogramming has not taken place, reprogram the ECM using
a Tech 2 scan tool with the calibration update from TIS2Web.
Refer to the latest version of Technical Service Bulletin 06-06-04-010 and Service Information to perform the ECM Reprogramming procedure and, if
needed, the Fuel Composition Reset Procedure. The Fuel Composition Reset Procedure is only needed if the measured ethanol content is more than 15%
different than the ECM estimated value.
IMPORTANT:
If it is assured that only non-blended (containing 10% or less ethanol) gasoline is in the vehicle fuel tank, proceeded directly to ECM programming.
