Warranty Information
Note: Stable battery voltage is critical during
programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. Install a GM
Authorized Programming Support Tool to maintain
system voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12 V jumper or booster pack disconnected
from the AC voltage supply. DO NOT connect a battery
charger.
Important: Warranty coverage code E2 applies for this
module programming event. ECM reprogramming is
covered for 8 years/80,000 miles (U.S.) or 8 years/
130,000 km (Canada).
For vehicles repaired under the Emission coverage,
use the following labor operation. Reference the
Applicable Warranties section of Investigate Vehicle
History (IVH) for coverage information.
If reprogramming the ECM, refer to K20 Engine Control
Module: Programming and Setup in SI.

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.
