INSPECTION OF ASC INDICATOR LAMP,
ASC OFF INDICATOR LAMP, ABS
WARNING LAMP AND BRAKE WARNING
LAMP
M1357000600012
Check that the ASC indicator lamp, ASC OFF indica-
tor lamp, ABS warning lamp, and brake warning
lamp illuminate as follows.
NOTE: The EBD warning lamp is also used as the
brake warning lamp.
1. When the ignition switch is turned ON, the ASC
indicator lamp, ASC OFF indicator lamp, ABS
warning lamp, and brake warning lamp illuminate.
2. The ASC indicator lamp, ASC OFF indicator lamp,
ABS warning lamp, and brake warning lamp
illuminate for three seconds
*1
and then
extinguishes
*2
.
3. Otherwise, check the diagnosis code.
NOTE:
.
•
*1
: The ABS warning lamp may illuminate 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
(start-up check).
•
*2
: The lamp does not turn OFF when the parking
brake is applied or the brake fluid level is low-
ered.

CAUTION
During diagnosis, a diagnosis code associated with other system may be set when the ignition switch
is turned on with connector(s) disconnected. On completion, confirm all systems for diagnosis
code(s). If diagnosis code(s) are set, erase them all.
