Hello all, can someone tell me why these lights are on? When do I connect to my scan device it tells me the code is not in the database? However, there is no update yet.

Why are they on?

 

ABS issue most likely, try the key trick and see what comes up. Not all scanners are ABS capable

Otherwise most auto parts stores will scan for free. If front sensor code pull sensor and check for metal could be a bad wheel bearing

 

Most likely you have a damage or open wheel speed sensor. Could also be the ABS module if you have 4 wheel ABS. Scan for code and post your finding.

 

I only have 2W ABS on this truck so I will check it out.

 

May want to check out the RWAL sensor on the diff, problem may be obvious.

 

Thank you, I have narrowed it down to that and I'll be replacing that sensor very shortly.

 

Well, I want to say thank you all for the advice. I changed the ABS sensor and that did the trick. Everything is working now. I also changed the shocks will I was under there.

 

It was the shocks that did it.

 

You know you might be right. I'm going to put the old shocks back in and see what happens? Can you please hold my beer?

 

I'll likely drink it.......
