There would be x minutes of data available. You said the car has been driven since. If the 'black box' is in the car, the data is now gone. 'Curly' |

Re: "Black Box" information retention?
reminds me of the joke about Bubba.
the black box was set up to record voices just before a collision. Bubba's last words were 'Hold this beer and I'll show you a trick'.

Re: "Black Box" information retention?
If by "black box" you are referring to the SRS (supplemental restraint system)
Unit. The answer is YES. Yes the SRS unit does store limited data, but only at the time of a deployment event. Dealers can only access DTCs with their scan tool, and nothing else (as related to deployment events.) Any Honda/Acura SRS Unit that can store DTCs, can and will store "deployment" DTC(s) at the time of deployment. This event data only records at the time, of a deployment. The SRS Unit does not know the date, time, or speed of the vehicle, at the time of deployment. What it does know and record, in permanent memory, is which seat belt was buckled, vehicle deceleration rate (in ms), which airbags, buckles or belt tensioners deployed. Cars with OPDS, SWS or ODS might also record front passenger weight (SWS/ODS), and front passenger position (OPDS/ODS), at the time of the deployment. So, in conclusion, no deployment, no data stored. -- Tp, -------- __o ----- -\<. -------- __o --- ( )/ ( ) ---- -\<. -------------------- ( )/ ( ) ----------------------------------------- No Lawsuit Ever Fixed A Moron... |
