DO NOT attempt to repair this concern if non-OE converters are found. Advise the customer that they need to return
the vehicle to original OE equipped components. If the converters and/or exhaust system are OE and there are no
other issues found, such as aftermarket calibrations per the latest version of Service Bulletin 09-06-04-026 etc., then
proceed with applicable SI diagnostic procedures.
Important: Having non-OE components installed could also result in a Powertrain warranty block.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
