Check that ABS and brake warning
lamps, ASC indicator lamp, ASC OFF indicator lamp illuminate
as follows.
|
|
1.When the ignition switch
is turned to the ON position, ABS and brake warning lamps,
ASC indicator lamp, ASC OFF indicator lamp
illuminate.
2.The ABS and brake warning lamps, ASC
indicator lamp, ASC OFF indicator lamp illuminate for three
seconds*1 and then turn
OFF*2
3.Otherwise, check the
diagnosis code.
| note |
- *1: The ABS warning
lamp, ASC indicator lamp may stay ON
until the vehicle speed reaches 10
km/h. As far as ASC-ECU sets 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 indicator
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.
