ACTUATOR TEST REFERENCE TABLE

M13506100098USA0000010000

Using scan tool, the following actuators can be forcibly
operated:

NOTE:

ABS, TCL, and ASC are operated by ASC-ECU.

When  ASC-ECU  is  disabled  due  to  the  fail-safe
function, the actuator test cannot be performed.

The actuator test can be performed only when the
vehicle is stationary.

While  the  actuator  test  is  performed,  the  ABS
warning light flashes at a rate of 2 Hz.

After  the  actuator  test  has  been  performed,  the
brake  warning  light,  ABS  warning  light,  ASC  ON
indicator  light,  and  ASC  OFF  indicator  light
illuminate until the ignition switch is turned to ON
again or the communication between scan tool and
ASC-ECU is terminated.
