The sample time accuracy requirement for pre-crash time is −0.1 to 1.0 sec (e.g., T = −1 would need to occur between −1.1 and 0 seconds.)\n2 The frontal air bag warning lamp is the readiness indicator specified in S4.5.2 of FMVSS No. 208 and may also illuminate to indicate a malfunction in another part of the deployable restraint system.\n3 The ignition cycle at the time of download is not required to be recorded at the time of the crash, but shall be reported during the download process.\n4 Except as provided in the following phase-in, for vehicles equipped with an EDR manufactured before September 1, 2031, the required recording interval is −5.0 to 0 sec relative to time zero and the required data sample rate is 2 samples per second. For vehicles manufactured on or after September 1, 2028 but before August 31, 2029, 25 percent of each manufacturer's vehicle production equipped with an EDR must have the recording interval and data sample rate displayed in this table. For vehicles manufactured on or after September 1, 2029 but before August 31, 2030, 50 percent of each manufacturer's vehicle production equipped with an EDR must have the recording interval and data sample rate displayed in this table. For vehicles manufactured on or after September 1, 2030 but before August 31, 2031, 75 percent of each manufacturer's vehicle production equipped with an EDR must have the recording interval and data sample rate displayed in this table. For vehicles equipped with an EDR manufactured before September 1, 2032 by a small-volume manufacturer or limited-line manufacturer, the required recording interval is −5.0 to 0 sec relative to time zero and the required data sample rate is 2 samples per second. For vehicles equipped with an EDR manufactured before September 1, 2033 by manufacturers producing altered vehicles or vehicles in two or more stages, the required recording interval is −5.0 to 0 sec relative to time zero and the required data sample rate is 2 samples per second.\n(b) Data elements required for vehicles under specified conditions. Each vehicle equipped with an EDR must record each of the data elements listed in column 1 of table II to § 563.7(b) for which the vehicle meets the condition specified in column 2 of that table, during the interval/time and at the sample rate specified in that table.\nTable II to § 563.7(b)—Data Elements Required for Vehicles Under Specified Minimum Conditions\nData element name Condition for requirement Recording interval/time 1 (relative to time zero) Data sample rate (per second)\nLateral acceleration If recorded 2 N/A N/A\nLongitudinal acceleration If recorded N/A N/A\nNormal acceleration If recorded N/A N/A\nDelta-V, lateral If recorded 0-250 ms or 0 to End of Event Time plus 30 ms, whichever is shorter 100\nMaximum delta-V, lateral If recorded 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A\nTime maximum delta-V, lateral If recorded 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A\nTime for maximum delta-V, resultant If recorded 0-300 ms or 0 to End of Event Time plus 30 ms, whichever is shorter N/A\nEngine rpm If recorded −20 to 0 sec 5 5 10\nVehicle roll angle If recorded −1.0 up to 5.0 sec 3 10\nABS activity (engaged, non-engaged) If recorded −20 to 0 sec 5 5 10\nStability control (on, off, or engaged) If recorded −20 to 0 sec 5 5 10\nSteering input If recorded −20 to 0 sec 5 5 10\nSafety belt status, right front passenger (buckled, not buckled) If recorded −1.0 sec N/A\nFrontal air bag suppression switch status, right front passenger (on, off, or auto) If recorded −1.0 sec N/A\nFrontal air bag deployment, time to nth stage, driver 4 If equipped with a driver's frontal air bag with a multi-stage inflator Event N/A\nFrontal air bag deployment, time to nth stage, right front passenger 4 If equipped with a right front passenger's frontal air bag with a multi-stage inflator Event N/A\nFrontal air bag deployment, nth stage disposal, driver, Y/N (whether the nth stage deployment was for occupant restraint or propellant disposal purposes) If recorded Event N/A\nFrontal air bag deployment, nth stage disposal, right front passenger, Y/N (whether the nth stage deployment was for occupant restraint or propellant disposal purposes) If recorded Event N/A\nSide air bag deployment, time to deploy, driver If recorded Event N/A\nSide air bag deployment, time to deploy, right front passenger If recorded Event N/A\nSide curtain/tube air bag deployment, time to deploy, driver side If recorded Event N/A\nSide curtain/tube air bag deployment, time to deploy, right side If recorded Event N/A\nPretensioner deployment, time to fire, driver If recorded Event N/A\nPretensioner deployment, time to fire, right front passenger If recorded Event N/A\nSeat track position switch, foremost, status, driver If recorded -1.0 sec N/A\nSeat track position switch, foremost, status, right front passenger If recorded -1.0 sec N/A\nOccupant size classification, driver If recorded -1.0 sec N/A\nOccupant size classification, right front passenger If recorded -1.0 sec N/A\nOccupant position classification, driver If recorded -1.0 sec N/A\nOccupant position classification, right front passenger If recorded -1.0 sec N/A\n1 Pre-crash data and crash data are asynchronous. The sample time accuracy requirement for pre-crash time is −0.1 to 1.0 sec (e.g., T = −1 would need to occur between −1.1 and 0 seconds.)\n2 “If recorded” means if the data is recorded in non-volatile memory for the purpose of subsequent downloading.\n3 “vehicle roll angle” may be recorded in any time duration; −1.0 sec to 5.0 sec is suggested.\n4 List this element n—1 times, once for each stage of a multi-stage air bag system.\n5 Except as provided in the following phase-in, for vehicles equipped with an EDR manufactured before September 1, 2031, the required recording interval is −5.0 to 0 sec relative to time zero and the required data sample rate is 2 samples per second.
