Antilock and ACD Fault Codes
So I recently pinned connectors 1 and 4 of my OBD2 port to troubleshoot my ACD and Antilock lights. For some context I have a 2006 Evo IX with 75k miles. At about 40 MPH all three ACD lights turn on. Antilock lights comes on right away. As well when checking to see if the ACD pump makes pressure, it makes proper pressure and stops once it reaches it so I'm assuming my pump is ok.
The codes are got are as follows:
ACD codes:
21 FR wheel speed sensor fault
25 Wrong Diameter tire
26 Wheel speed sensor fault (I assume this is my FR sensor
Antilock codes:
11
21
I don't know what these codes are and I've tried searching on here without much luck. Since I'm doing the alternator soon, I'm gonna go ahead and do the sensor too while I'm at it. Hopefully putting on a new sensor will fix my ACD issue. If anyone has any ideas please let me know, thanks.
