Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling .
Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

Important:
| • | In order to prevent accidental deployment, the shorting bars close in
order to short the connectors when the connectors are separated. |
| • | 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
(0.25 in) |
