tineira Posted January 2 Report Share Posted January 2 How long should the Fault Code Clear Switch be active for it to clear the check engine light? I have tried up to 500 ms and it does not always work, but it would be nice to have a definitive answer on this. I'm using a CAN DI as the input.

Adamw Posted January 2 Report Share Posted January 2 I get quite variable results also. I had a range between 0.1 and 0.8s with a quick test I done. I suspect it is only being run in a slow loop so it wont be "seen" until the next loop comes around and assesses the switch state. I will get @Vaughan to confirm when he's back from holiday.

tineira Posted January 2 Author Report Share Posted January 2 Thanks, having the polling ratio for these values should be helpful. The same info for log marker would be great. Quote Link to comment Share on other sites More sharing options...
