Data elements required for all vehicles.(a) Each vehicle equipped with an EDR must record all of the data elements listed in table I to § 563.7(a), during the interval/time and at the sample rate specified in that table.

Data elements required for vehicles under specified conditions.(b) 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.

The sample time accuracy requirement for pre-crash time is −0.1 to 1.0 sec ( T = −1 would need to occur between −1.1 and 0 seconds.) 2 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. 3 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. 4 For vehicles manufactured before September 1, 2027, 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 before September 1, 2029 by small-volume manufacturers and limited-line manufacturers, 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 before September 1, 2030 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.
