whats up with this ?? Anyone? could it be from T/C lockup switch...haven't had this code before

 

NO IDEAS HERE??thanks

 

That code is related to TC voltages. Did you use a 33ohm resistor when you installed the lockup switch? Have you stalled the truck with the TC locked up?

 

1) no
2) no (almost though)

 

I think either one (or both) of those will throw that code. I know if you let the truck stall (or maybe come close?) it will throw that code. Not positive on the resistor, but I've heard that can cause it also.

I would add a resistor and clear the code with your Smarty. It shouldn't come back unless the truck stalls with the TC locked.

 

ok thanks I'll try it(resistor) ...Ive had the switch for weeks and use it every night ( I travel 22 miles @35-42mph ,to lock for better mpg) and haven't gotten this before now though

 

UPDATE... Drove to and from work with SMARTY on 3 and ,NOT IN "TOW MODE" and did NOT use the lock switch

Drove to work 'like a little old lady'....NO CODES

Drove home ...Normal (no tow or lock) mashed on her a FEW times...NO CODES

so I will see if I cant find a 33... all I can find is 22's (2 tandom?)

 

Ive got the switch and the resistor and my light comes on ( with the same code as yours if I remember) about every few months or so....I've also stalled it with the switch a few times but it doesn't seem to relate to when the light comes on...
I just reset it w/Smarty and am on my way.

Wonder if my resistor is "burnt out" or something, cause it seems to happen more now than when I first installed it,

forgot to update


Installed resister in ground side ...NO MORE CODES
