For detailed information, refer to the brake sup- port systems → page 131. The associated data el- ement is the “traction control system status” in Class B, which may have the following status: – Switched on and activated – Switched on but deactivated – Switched off – Malfunction Description of the recorded Class A data element 182.5C1.TRO.74 Customer information 219 No. Name Description 7 Driver's seat belt status Status of the driver's seat belt buckle. 8 Accelerator po- sition, percent- age relative to full open posi- tion The percentage of the ac- tual position of the accel- erator to the driver's fully depressed position.
9 Revolutions per minute (r/ min) The revolutions per mi- nute of the engine's main crankshaft 10 Event power cycle count The number of power cy- cles recorded in the ECU that captures EDR data since its initial use to the occurrence of the event. An example of a power cycle is when the ignition is switched from “off/ assist” mode to “on/run” mode. 11 Event power cycle count at retrieval The number of power cy- cles recorded in the ECU that captures EDR data since its initial use until the data retrieval. An ex- ample of a power cycle is when the ignition is switched from “off/ assist” mode to “on/run” mode.
12 Event data re- cording com- plete status Status flag of whether the event data is fully re- corded and stored in the ECU that records the EDR data. 13 Time interval between this event and the last event If two events occur with- in 5 seconds, the time is the elapsed time be- tween the start of event X and the start of event X-1. 14 with vehicle identification number The vehicle identification number (VIN) assigned by the vehicle manufacturer. 15 ECU hardware number for re- cording EDR data The ECU hardware num- ber in the vehicle that im- plements the EDR re- cording function. No. Name Description 1 Longitudinal delta-V The variation of vehicle longitudinal speed.
Lon- gitudinal delta-V is only the longitudinal compo- nent of the total delta-V. 2 Maximum re- corded longi- tudinal delta-V Maximum longitudinal vehicle speed accumula- tion recorded by the EDR. This data should be used in conjunction with “Time to maximum delta-V, lon- gitudinal”. 3 Time to reach maximum re- corded longi- tudinal delta-V The time taken from time zero to the maximum val- ue of the cumulative change in speed, along the X-axis, as recorded by the EDR. This data should be used in conjunction with “Maximum recorded longitudinal delta-V”. 4 Clipping flag Indicates the point at which the acceleration (lateral, longitudinal) col- lected by the EDR first reaches the sensor range.
5 Vehicle speed The wheel speed or the vehicle speed obtained by other means. Data accu- racy can be affected by factors such as significant deviations in tyre size compared to factory set- tings and wheel lock or wheel slip. 6 Service brake, on or off Used to detect whether the driver has depressed the brake pedal.
