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: Twisted-pair or twisted-triplet 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 wires shown :
This specification applies to all twisted wires within the IP harness
| • | 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). |
| • | The drain wire must be placed along the length of the twisted wires. |
| • | The twisted wires and the drain wire must be continuously covered by shield
tape, aluminum side inward. The shield tape must be covered with tape. |
This specification applies to only shielded wires within the body
harness, IP harness, and roof harness
| • | The wire must be continuously covered by shield tape, aluminum side inward. |
| • | The drain wire must be placed along the length of the shielded wire and
covered with tape. |
