The car seems to run fine but I've got ABS and VDC lights on.  I put in the connecting wire to get the codes, I would like help with "reading the code".  Here's the flash pattern.

 I am unsure if a count every flash.    The pattern repeats, and is made of long flashes (I) and short ones (i) and spaces..   Here's my break down. Long one, short one, space, , 7 long, 1short, space,  7long, 4 short, space,  four long, 9 short then quickly repeat.  If I count all of them I get 34,  Front left outlet valve? 

 

Here's a link to the codes. 

thanks in advance.

Year & model of car?

Oops,  It's a 2001 OBW with the H6.  Around 136K.

abs is very sensitive to voltage, check that.

ever replace the alternator? MANY, many folks have installed incorrect/poor rebuilt alternators.

Yes, the alternator looks like it has been replaced.  I've owned the car for around four years and can't remember if I did it, but if I did it was years ago.  I usually get NAPA parts.  Should I check the voltage after disconnection the wires?  Is the ABS disabled currently?

   

hard to say about ABS function, you could have a bad wheel sensor or other issue....But checking voltage should be easy and is a known problem area.

 

Thanks Texan, in the next couple of weeks I will be checking this out.  I will check voltage and see if I can identify the manafacture of the alt.
