qustions about FBH

please don't groan for yet another FBH question :)

I think I have understood that if I apply an earth to start the FBH but remove it after a few seconds or sooner that if I did this enough times the PCB locks out.

Question 1
If, when the temperature is below zero I start the car and then 5 - 10 seconds later turn it off (just need to move car out the way) and I do this enough times, can the PCB lock out?

Question 2
If the FBH in between each brief start of start up procedure, is allowed to fully start and run, will this cancel any "false" starts?

Drop Trebor Or Devilish a line. They will tell you. I think that it won’t do it any harm once or twice, but you could leave it running for around ten minutes, but don’t forget it uses 40 watts. You will also probably get some white smoke out the exhaust if you stop it to quick. It runs a clearing cycle before shutting down.

If you do it enough times you will get fed up, that is all. A lockout is not stored in physical memory, lockout is sort of remembered, when power is cut, it forgets.

No, if it did, every FBH would be locked out at some point. I would be dealing with lockouts every week. Also "Ian tapping start command" is not a recognised in the software as a fault

No, only 1 way to clear faults from memory.
