SIR Schematic Icons Icon Icon Definition CAUTION: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Zone Identification Views . Failure to observe the correct procedure could cause deployment of the SIR components, personal injury or unnecessary SIR system repairs. 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. The following specification applies to all twisted wires except within the body 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 (0.25 in). The following specification applies to all twisted wires within the body harness: The wires must be twisted a minimum of 12 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)

Passenger Presence System Indicator Circuit Malfunction

Frontal SIR System Description

The frontal supplemental inflatable restraint (SIR) system consists of the following components

  1. AIR BAG indicator located in the instrument panel cluster (IPC)
  2. Driver and passenger knee bolsters
  3. Inflatable restraint instrument panel (I/P) module.
  4. Inflatable restraint sensing and diagnostic module (SDM)
  5. Steering wheel and column
  6. Inflatable restraint steering wheel module
  7. Inflatable restraint steering wheel module coil
  8. Inflatable restraint wiring harnesses
  9. Inflatable restraint front end sensor (left/right)
  10. Inflatable restraint Passenger AIR BAG ON/OFF indicator
  11. Inflatable restraint passenger presence system (PPS)
  12. Inflatable restraint seat belt retractors pretensioner (left/right)

A frontal collision of sufficient force up to 30 degrees off the longitudinal centerline of the vehicle will deploy the frontal air bags. The SDM contains a sensing device that converts vehicle velocity changes to an electrical signal. In the event of a frontal collision, the SDM receives a signal from the front end sensor, which assists the SDM in determining the severity of the collision. The SDM compares these signals to a value stored in memory. When the generated signals exceed the stored value, the SDM will cause current to flow through the frontal deployment loops simultaneously deploying the frontal air bags. The SDM, I/P module, steering wheel module, steering wheel module coil and the connecting wires makeup the frontal deployment loops. The SDM continuously monitors the deployment loops for malfunctions and turns the AIR BAG indicator ON if a fault is detected.

Side SIR System Description

The Side Supplemental Inflatable Restraint (SIR) System consists of the following components

  1. AIR BAG indicator located in the instrument panel cluster (IPC)
  2. Inflatable restraint sensing and diagnostic module (SDM)

  4. Inflatable restraint side impact modules (left/right), front and rear (w/rear bucket seats)
  5. Inflatable restraint wiring harnesses
