To detect a leak, it only looks at one thing. The hall effect switch on the
Leak Detection Pump, aka LDP.
Operating conditions must be right to run the test, and it will look at other
sensors for that info, but they aren't used to detect leaks.

Re: Smooth driver
Had a similar - not the cap but the light not coming on...must have left the cap in
Placerville when filling the spare cans. Didnt notice it (no lights on at all) until
the next morning at Icehouse. You would think that no cap would do something, when
on so many rigs a loose cap will turn the stupid check engine light on. <shrug>
Least you didnt have to pay for a new cap. =)
