so, I have had an issue with the driver side front going into ABS braking at low speed which has been getting worse and worse and I was about to pull a ABS sensor as it was doing my head in.
so finally I get "VSC OFF ABS VSC" lights, having the APP Torque which as is crap for ABS codes I was stuck, i was about to go a buy a posh code reader when I thought would search google play with this search "ODB2 Toyota", bingo ELMScan Toyota, downloaded the Demo and you can access the ABS ECU.
There where 4 error codes, but they could be old so I purchased the full app cleared the codes, VSC light goes off, back to ABS braking again, two days later light goes on again, checked code LR Speed sensor.....hmmm so why is the front ABS kicking in?
I don't trust the error, but I found a really good thing on the ELMSCAN you can graph the ABS sensors:
I added the two front sensors and drove around and they where perfect no jitters or issues both went up and the same speed.
Did the back two, well at 15 MPH all fine, under that LR was jittering like hell, so it looks like the speed ring is game over, which looks like a drive shaft change.
so the purpose of the post:
ELMSCAN Toyota is a brilliant tool, I cannot recommend it more.
and why the fook does the car engage drivers ABS at the front when the Speed ring is fooked on the LR?
