NOTE
Even if failures of a same code repeatedly occur, the code that is displayed is the one stored for the first time only,

Actuator Test
The actuator can be force-driven using the scan
tool for easy operation inspection,
NOTE
(1) If the ABS-ECU function has been cancelled,
an actuator test cannot be performed.
(2) Actuator testing is only possible when the ve-
hicle is stationary. If the vehicle speed during
actuator testing exceeds
IO
km/h (6 mph),
forced actuation will be cancelled.
(3) The following item numbers are those to be
entered on the scan tool to give an actuator
test instruction.
