Brake status “on” and ABS “on” — reading the fields together

Case question
What can brake and ABS fields establish about pre-impact driver response?

What the evidence showed
A Corolla pre-crash record showed brake status changing to on with ABS engaged at the final sample. The report also preserved speed and steering information over the same interval, allowing the braking evidence to be read in context.

Practical takeaway
A brake-status field can show a recorded state, but it is not a complete mechanical inspection. Use it together with speed change, ABS state, timing and physical brake evidence.

Reading the exhibit
Deceleration and distance-to-impact columns are derived from sampled speed, not independent EDR measurements. Distance is approximate displacement before the final pre-crash sample; sampling gaps, wheel slip, sensor latency and incomplete data can affect it. Read the calculated values with scene evidence and the source report’s limits.
The source evidence exhibit is provided below.
