Data supplied by Vetronix Corp.

For Vehicles that correspond with the 02002888 cable, the following data is available from the airbag module for recorded Deployment and Near-Deployment files:

Data Summary Table
  • SIR Warning Lamp Status (ON/OFF).
  • Driver’s Belt Switch Circuit Status (Buckled/Unbuckled).
  • Passenger Front Airbag Suppression Switch Circuit Status (ON/OFF).
  • Ignition Cycles at Deployment/Near-Deployment.
  • Ignition Cycles at Investigation.
  • Time from Algorithm Enable to Deployment Command (msec).
  • Time From Near-Deployment to Deployment Command (sec) (If within 5 seconds).

Post-Crash Graph: SDM Recorded Velocity Change

  • Plots Change in Forward Velocity (MPH) Versus Time for 300 msec After Algorithm Enable.

*Note: 1999 vehicles that correspond with the 02002828 cable will have Pre-Crash Data in addition to Data Summary Table and Post-Crash Data.



For Vehicles that correspond with the 02002829 cable, the following data is available from the airbag module for recorded Deployment and Near-Deployment files:

Pre-Crash Graph
  • Vehicle Speed 5 Seconds Before Algorithm Enable (MPH).
  • Engine Speed 5 Seconds Before Algorithm Enable (RPM).
  • Percent Throttle 5 Seconds Before Algorithm Enable.
  • Brake Switch Circuit Status 5 Seconds Before Algorithm Enable (ON/OFF).

Data Summary Table
  • SIR Warning Lamp Status (ON/OFF).
  • Driver’s Belt Switch Circuit Status (Buckled/Unbuckled).
  • Passenger Front Airbag Suppression Switch Circuit Status (ON/OFF).
  • Ignition Cycles at Deployment/Near-Deployment.
  • Time Between Deployment and Near-Deployment Events (msec) (If within 5 seconds).
