BRAKE CONTROL – VEHICLE STABILITY CONTROL SYSTEMBC–49
BC
• *4: w/ 16-inch disc
• The DTCs can be read by connecting SST (09843-
18040) between the TC and CG terminals of the
DLC3 and observing the blinking pattern of the ABS
and VSC warning lights, or by using an intelligent
tester (see page BC-47).
• This system has a sensor signal check function (see
page BC-28).
2. CHECK WARNING LIGHT AND INDICATOR LIGHT
(a) Release the parking brake lever.
NOTICE:
Before releasing the parking brake lever, set
chocks to hold the vehicle for safety.
HINT:
When the parking brake is applied or the brake fluid
level is low, the brake warning light comes on.
(b) When the ignition switch is turned ON, check that
the ABS, VSC and brake warning lights and the slip,
downhill assist control and AUTO LSD indicator
lights come on and go off in about 3 seconds.
HINT:
If the warning lights do not illuminate, confirm
whether the bulbs have burned out, and also check
for CAN communication system DTCs, since the
skid control ECU and combination meter are
connected by the CAN communication line.
If the warning light remains on, perform relevant
troubleshooting procedures. The relevant
troubleshooting procedures are in the sections listed
in the table below.
