• As an example, the blinking patterns of the
normal system code and DTCs 11 and 21 are
shown below.
• DTCs are explained in the "DIAGNOSTIC
TROUBLE CODE CHART" (see page BC-57).
(d) After completing the check, disconnect SST from
terminals 13 (TC) and 4 (CG) of the DLC3, and turn
the ignition switch OFF.
HINT:
• If 2 or more malfunctions are detected at the
same time, the lowest numbered DTC is
displayed first.
4. CLEAR DTC (When not Using Intelligent Tester)
(a) Using SST, connect terminals 13 (TC) and 4 (CG) of
the DLC3.
SST 09843-18040
(b) Turn the ignition switch ON.

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".

2. PARFORM ACTIVE TEST
HINT:
Performing the intelligent tester's ACTIVE TEST allows
relay, VSV, actuator and other items to be operated
without removing any parts. Performing the ACTIVE
TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE
TEST.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Turn the intelligent tester on.
(d) Perform the ACTIVE TEST according to the display
on the tester.
HINT:
• The ignition switch must be turned ON to
proceed to the ACTIVE TEST using the
intelligent tester.
• The ACTIVE TESTs of the ABS solenoid, ABS
motor relay, ABS warning light and BRAKE
warning light are available when the vehicle is
stopped.
• The motors stop automatically after 5 seconds of
activation to prevent them from being damaged.
When the motors are driven repeatedly, certain
intervals are required.
• Each solenoid stops automatically after 2
seconds of activation to prevent them from being
damaged, and can be operated again after a
certain interval.
• Do not depress the brake pedal while only the
pressure reduction solenoid valves are on.
• Do not drive 2 or more solenoids simultaneously
except to operate the pressure holding solenoid
valves and pressure reduction solenoid valves of
each wheel.

If the result is not as specified, the ECU may have a
malfunction.
DIAGNOSIS SYSTEM
1. CHECK DLC3
(a) Check the DLC3:
The power steering ECU uses CAN (ISO11898-1)
and ISO9141-2 for communication protocol. The
terminal arrangement of the DLC3 complies with
SAE J1962 and matches the ISO9141-2 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, other switches or
the doors.
If the result is not as specified, the DLC3 may have
a malfunction. Repair or replace the harness and
connector.
HINT:
Connect the cable of the intelligent tester to the
DLC3, turn the ignition switch ON and attempt to
use the tester. If the display indicates that a
communication error has occurred, there is a
problem either with the vehicle or with the tester.
