    Default FJ Cruiser ABS/VSC/TRAC Lights

    A common failure in certain Toyota models, including the FJ Cruiser, is the intermittent error that turns on the ABS/VSC/TRAC lights on the dash:

    Quite often, the solution is to replace the stop light switch:

    Installation is the reverse of removal (one of my favorite phrases).

    Enjoy safe driving with the now-working ABS and Stability Control systems.

    What did the stop light switch have to do with the said indicators coming on unnecessarily?

    The VSC/ABS CPU needs to know that the brake pedal has been pressed by the switch. The master cylinder pressure switch is also monitored for the voltage change that tells the CPU what is the force on the brake pedal. If there is no or erratic signal from the stop switch but the master cylinder pressure switch shows a change, it sets error code C1246. If changing the stop switch does not clear the code, then the fault is in the master cylinder itself.

    Good explanation. Thank you. Though I wonder why the sensor is connected to the light circuit in the first place?
