Your ABS connector, by your fuse block under the hood:

Pin 2, the orange/white wire, is the wire you want to ground with the key off. Then turn the key on and count the number of times your ABS light flashes. This is your code. Here's a list:

12 - system ok
19 - anti-lock control module
22 - right front valve
24 - left front valve
26 - rear valve
31 - right front ABS sensor continuity fault
32 - right rear ABS sensor continuity fault
33 - left front ABS sensor continuity fault
34 - left rear ABS sensor continuity fault
41 - right front ABS sensor
42 - right rear ABS sensor
43 - left front ABS sensor
44 - left rear ABS sensor
61 - pump motor/pump motor relay fault
63 - voltage supply interruption
69 - vehicle battery voltage less than 10VDC
78 - ABS sensor frequency fault


I had code 78 because I had 40 sidewall series tires on the back and 35's on the front.

my abs light is on almost all the time, sometimes it takes a little to go off, i havent ran the test but it could throw the abs light if i have low profile tires? i think i have 30s on the rear, i dont remember the front, most likely the same

Um, so what does this mean? why would that have anything to do with it if the tires dont have anything to do with it

It means the back tires were taller.



That makes them spin slower than the fronts, the computer sees an irregularity between the fronts and the rears, then you get an ABS light.
