Engine was running rough and SES light doesn't work, so I stopped by O'Reily's to read the codes.

0304 - cylinder 4 misfire
1451 - unknown (old posts say SAI, i'll check the filter soon)
0447 - evaporative emission control system vent control circuit open

The guy said the 447 is a loose or leaky gas cap. Reset, the misfire went away, so nothing too serious, and it seems to be running better. Whew, for now...

But while I was under the dash, I noticed a tiny toggle switch at the bottom of the trim right under the steering column. Anybody have any idea what this thing does?

 

PICS PLEASE....of the toggle, not the codes

Does it look aftermarket?

 

Sorry for poor quality. Looks after market, but there's been nothing added to this truck.

 

That is for the machine guns (DI); Rocket Launcher (DII).

 

Definitely aftermarket. Do you have an aftermarket alarm system? It looks like a valet(bypass) switch.

 

Actually, it is the self-destruct buttom for use when the sleeves slip. Phil

 

That button is permanently activated from the factory. It's a feature.

 

Looks like the valet switches I've had in other cars with alarms.

Start the truck, flick the switch, whats so hard about that?

 

That has to win post of the year...........Hey Phil...are you on the absolute yet? My wife swears by absolute sea breeze's now.... LOL
