I have some codes,

U0100 Lost Communication with Ecm/pcm

B1630 right low beam control circuit open

B1660 Front Fog lamp control circuit high

check engine light never came on, one mechanic used his scanner said these codes were for O2 sensor & Catylitic conv. That info doesnt match my research on those codes.
Any experience with these codes?
FYI i have HID low beam & fog, also fogs have some type of relay installed to get rid of flickering.

 

Ignore the B codes.


I have no idea how he gets cat from a U0100 ??


What module was the U0100 present in ?

 

No idea what that means. after mechanic scanned, i rescanned using my superchips scanner. Could it be my scanner didnt pick up the codes his scanner picked up?

 

Its official, i didnt pass California smog check twice. I did clear the codes. Failed. Then ran truck a week/200 miles and failed again. Anyone have any ideas on what i can do to trouble shoot before i take to dealer and drop some $$$

 

What is it failing for?

 

"Obd2 Not Ready" not to mention visual inspection fail due to CAI and Electric Exhaust cut offs.

 

So even if you get the readiness monitors set, it will still fail.

 

Move...


vote out the idiots that are running your life...


or go to the dealer and drop some $$$

 

Putting my truck back to stock is no problem, i just want to make sure i take care of the main issue, obd2 not ready, once that is done i will put back to stock.
