3. CHECK INSTRUMENT PANEL JUNCTION BLOCK
(MAIN BODY ECU)
(a) Disconnect the ID junction block connector.
(b) Measure the resistance of the wire harness side
connector.
If the result is not as specified, there may be a
malfunction on the wire harness side.
(c) Reconnect the ID junction block connector.

• *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.

FREEZE FRAME DATA
1. FREEZE FRAME DATA
HINT:
• Whenever a DTC is detected or the ABS operates,
the skid control ECU stores the current vehicle
(sensor) state as freeze frame data.
• The skid control ECU stores the number of times
(maximum: 31) the ignition switch has been turned
from OFF to ON since the last time the ABS was
activated. However, if the vehicle was stationary or
running at a low speed (7 km/h [4.3 mph] or less), or if
a DTC is detected, the skid control ECU stops
counting.
• Freeze frame data at the time the ABS operates:
The skid control ECU stores and updates the data
whenever the ABS system operates.
When the ECU stores data at the time a DTC is
detected, the data stored when the ABS operated is
erased.
• Freeze frame data at the time a DTC is detected:
When the skid control ECU stores data at the time a
DTC is detected, no updates will be performed until
the data is cleared.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester on.
(d) From the display on the tester, select "FREEZE
FRAME DATA".

DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
out removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Turn the intelligent tester on.
(d) Read the DATA LIST according to the display on the
tester.
