Someone in another forum said if i get the force tool to turn ignition on i can read the isn for cas4 and fem vehicles via obd. Is it possible with autohex? Im guessing maybe possible for cas4 but not fem.
Hello
With autohex tool you can read ISN from DME OBD even without ignition for F series but mainly upto 2013 cars. please keep hazard lights ON while doing this procedure. If you got any message like ECU not support you need to read it on bench in factory mode.
