Hi, I replaced my ABS module with a used one from a junkyard, and now I’m getting these DTCs: 86-13, 51-12, and 151-11. I checked all the wiring connections using the wiring diagram, and everything has a good connection with no shorts. However, I noticed something strange with DTC 151-11—it’s related to low tire air pressure, but my vehicle doesn’t have TPMS! This makes me think that the junkyard ABS module came from a different trim. Can Honda HDS fix this problem? Please confirm, as I don’t want to waste more money.

Yes, the Honda HDS system may be able to reprogram the module.

86-13 - ABS/TCS/Brake System Control Module Malfunction

This code is because the programming does not match the car. and the last two codes can go away once the correct problem has been installed/loaded.

51-12 - Lateral Acceleration Sensor Malfunction

151-11 - Low Tire Air Pressure Signal Malfunction

Bleed the brake system, this video can help:

Do the VSA modulator-control unit update
Do the VSA sensor neutral position memorization
Do the steering angle sensor neutral position clear

Here are the instructions on how to change out the ABS module correctly. Check out the images (below). Let us know how it goes.
