Check that ABS and brake warning
lamps, ASC warning/operation lamp illuminate as
follows.
|
|
1.When the ignition switch
is turned to the ON position, ABS and brake warning lamps,
ASC warning/operation lamp, ASC OFF lamp
illuminate. 2.The ABS and brake warning lamps, ASC
warning/operation lamp, ASC OFF lamp illuminate for
three seconds*1 and then turn
OFF*2. 3.Otherwise, check the
diagnosis code.
note |
- *1: The ABS warning
lamp, ASC warning/operation lamp,
ASC OFF lamp may stay ON until the
vehicle speed reaches 10 km/h. As
far as ASC-ECU stores any diagnosis code
related to the wheel speed sensor
malfunction or the motor malfunction as
past trouble, ASC-ECU continues
illuminating the ABS warning lamp until
it verifies that the malfunction for
that code is resolved (startup
check).
If the steering wheel sensor
or the G and yaw rate sensor system was
detected to be defective during ignition
switch being ON at the last time, the
ASC warning/operation lamp and the
ASC OFF lamp will illuminate until the
vehicle speed reaches approx. 10
km/h, then the steering wheel is
turned to either right or left and then
the ECU determines that the system is
normal.
- *2: The brake warning
lamp does not turn OFF when the parking
brake is applied or the brake fluid
level is lowered.
