Anyway around reprogramming an ABS unit

I can go back out there and hook it up. It supposedly can even bleed the unit. It’s smarter then I am.

 

An honesty I have replaced all 4 speed sensors but that’s what I have on my computer. Most stuff I don’t have a clue what it all means.

 

So those codes all come back immediately if you clear them even when the fuses are installed?

Do you have wheel speed sensors and IG voltage in your data list?

 

Click all data.

 

Last picture is with the fuses pulled and cleared and that code still shows there instantly.

 

sorry hit the post reply button and meant to hit upload a file button.

 

Well since the C0278 is persistent let's see if we can diagnose that first although I still don't see how that would affect your base brakes.

 

Well I’ve got no clue but it does. I had a Chevy avalanche once and it worked for that one. My Toyota is a complete different animal.

 

Yea GM had alot of ABS issues over the years with everything from speed sensors to the pumps getting stuck on the the ABS modules failing internally or even self destructing.
I rarely see a Toyota come in with an ABS issue though.

Well check your powers and grounds, I posted it above.

 

I greatly appreciate your help. I will get a tester tomorrow and see what I can find out. What kind / brand do you suggest picking up at my local part store ? Or harbor freight or something ? Once again I greatly appreciate your help.

 

Any voltmeter should be sufficient, grab you a test light too.

 

Thank you

 

And be careful not to shove anything into the connector and spread the terminals, all you need to do is touch the metal part of the pins.

 

Thank you again

 

Hope I’ve done this right.

 

Also the longer you hold it the lower the number keeps dropping.

 

Looks like your on the right pins, your fuses are installed correct?

If so go from the B+ pin to a good body ground and see what you have.

 

Yes they are installed correctly.
