Failure to follow the correct procedure could cause the following conditions: Air bag deployment Personal injury Unnecessary SIR system repairs In order to avoid the above conditions, observe the following guidelines: Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring. If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System in SIR.
Courtesy of GENERAL MOTORS CORP.	IMPORTANT: Twisted-pair wires provide an effective "shield" that helps protect sensitive electronic components from electrical interference. If the wires were covered with shielding, install new shielding. In order to prevent electrical interference from degrading the performance of the connected components, you must maintain the proper specification when making any repairs to the twisted-pair wires shown : The wires must be twisted a minimum of 9 turns per 31 cm (12 in) as measured anywhere along the length of the wires. The outside diameter of the twisted wires must not exceed 6.0 mm (0.2 in).
