how to check abs codes
This is for a tundra but supposed to be the same procedure.
found this on yotatech
The ECU doesn't show ABS codes. The OBDII interface doesn't show ABS codes. The ABS computer is where you pull ABS codes from, and it only comes from:
Turn the ignition ON (don't start the engine)
Pop the hood
Find the "DIAGNOSTICS" connector that's on the drivers side of the engine, on the high edge of the intake plenum.
Pop the top, and you'll see something like:
Code:
+---+---+---+
| | | |
+---+---+---+
| | | |
+---+---+---+
| | |E1 |
+---+---+---+
| |
+---+---+---+
| | | |
+---+---+---+
| |Tc | |

(front of truck)In the lower left, you'll find a small plug that pulls out. That's a "shorting pin", pull it.
Now use a piece of wire to jumper from E1 to Tc
Look back at the dash, the ABS light should be blinking.
The blinking is in a pattern. For example, if you see BLINK-BLINK {pause} BLINK-BLINK-BLINK {long pause} {repeat} that would be code "23"
Once you get the code, pull the jumper wire from E1/Tc, put back the shorting pin, and confirm that you can start the truck.
