Vsc, abs, and park brake light on

so those three lights came on all of a sudden. Reading past posts:

I figured it must be the faulty differential center lock switch. But when I disconnect this switch, if the lights are still on (but no others), does that confirm it to be the right switch?
And yes, I did check the appropriate fuses.
Edit: I checked the IG1 & IG2 fuses. Not sure which others to check.

 

Have you checked your brake fluid level?

 

Tacomas do not have a center differential lock switch. You'll need an OBDII scanner capable of reading ABS codes to see what the error codes are, I'm going to guess a speed sensor/wire is bad as that's common to all 3 functions of ABS, VSC, and EBD.





The EBD control utilizes ABS, realizing proper brake force distribution between the front and rear wheels in accordance with the driving conditions. In addition, when braking while cornering, it also controls the brake forces of the right and left wheels, helping to control the vehicle behavior

 

SOLVED! Right on the money, 6 gear. It was a loose wire in the rear, hidden in some previous owner's quick fix.
