2005 Corvette: GM TechLink: SIR Lamp On
Owners of some 2005 Chevrolet Corvettes may experience an SIR lamp after depressing the horn for more than 5 seconds or using the horn two or three times in succession. A current or history code B0104 or B0101 may be set in the SDM.
Make sure the horn bracket is properly attached and torqued to the skid bar assembly of the frame. If the concern still exists, advise the customer that Engineering is investigating the concern.
TIP: Replacing the SDM or the sensors will not resolve the concern.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
