Discuss the causes and fixes for C1225 Toyota OBDII Code

  • I have a Toyota Highlander 2001, I have both the ABS and brake light on, I actually bought it like that, but I hade bought a second hand ABS actuator hoping to solve my problem but yet it’s the same. Can anyone help please ?

  • Do you had the same code before replacing the ABS actuator?
    Unfortunately, other than the ABS actuator, I have not seen any other component setting the C1225 code.
    Make sure the ABS actuator connector pins are not damage and clean.
