CAUTION
Before connecting or disconnecting scan tool, always turn
the ignition switch to the LOCK (OFF) position.
2. Before setting scan tool, turn the ignition key to the LOCK
(OFF) position.
3. Confirm that the selector lever is in the "N" position, and
then start the engine.
4. When carrying out the actuator tests No.01 to 04, perform
the actuator tests using scan tool while depressing the brake
pedal. When carrying out the actuator tests No.05 to 08,
perform the actuator tests using scan tool without
depressing the brake pedal. When carrying out the actuator
tests, rotate the wheel by hands to confirm that the braking
force changes.
NOTE:
.
•
While performing the actuator test, the ABS warning light
flashes at a rate of 2 Hz.
•
When ASC-ECU is disabled due to the fail-safe function,
the scan tool actuator test cannot be performed.
•
After the actuator test has been performed, the ABS
warning light, brake waning 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.
