Installing an A-Trac
Switch
If you have an
FJ equipped with a rear locker the A-Trac
system can be activated simply be installing
a factory A-Trac switch. Evidently
most FJs are factory wired for the A-Trac
system even if the option was not included
on the original build. The switch can
be obtained from many sources for
approximately $50.

What is A-Trac?
The Toyota Active Traction system is
computer controlled traction control
available on various Toyota vehicles.
The system senses differences in wheel speed
and automatically transfers torque to a
wheel with more traction by applying a
certain amount of braking force to the
slipping wheel.

ground and has no traction. The a-trac
system applies braking force the slipping
