(3) Clear the DTCs stored in ECU by depressing the
brake pedal 8 or more times within 5 sec.
(4) Check that the ABS warning light indicates the nor-
mal code blinking pattern.
(5) Remove the SST from the DLC3.
SST 09843±18040
HINT:
Disconnecting the battery cable during repairs will not erase the
DTCs in the ECU.
(f) With using hand±held tester:
Clear the DTCs.
(1) Turn the ignition switch ON.
(2) Operate the hand±held tester to erase the codes.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.
2. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand±held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.

4. FREEZE FRAME DATA
(a) The vehicle (sensor) status memorized during ABS operation or at the time of error code detection can
be displayed using the hand±held tester.
(b) Only one record of the freeze frame data is stored and the freeze frame data generated during ABS
operation are constantly updated. Also, the number of the operations of the ignition switch ºONº after
the freeze frame data is stored can be memorized up to 31 and it can be displayed.
HINT:
If the ignition switch ºONº operation exceeds 31 times, º31º appears on the display.
(c) If the diagnosis code malfunction occurs, the freeze frame data at the occurrence of the malfunction
is stored but the ABS actuation data is not stored.

DIAGNOSTIC TROUBLE CODE CHART
HINT:

Using SST 09843±18040, connect the terminal Tc and CG of the DLC3.

If malfunction is not found when inspecting parts, inspect the ECU and grou\
nd points for poor contact.

If a malfunction code is displayed during the DTC check, check the circuit\
listed for that code. For de-
tails of each code, refer to the ºSee pageº for respective ºDTC No.º\
in the DTC chart.

When 2 or more DTCs are detected, perform circuit inspection one by one unti\
l the problem is identi-
fied.

DTC C0273/13 OPEN OR SHORT CIRCUIT IN ABS MOTOR
RELAY CIRCUIT
CIRCUIT DESCRIPTION
The ABS motor relay supplies power to the ABS pump motor. While the ABS & BA & TRC & VSC are acti-
vated, the ECU switches the motor relay ON and operates the ABS pump motor.
DTC No.DTC Detecting ConditionTrouble Area
C0273/13
Detection of any conditions from 1 to 3:
1. After actuation of the motor relay, pump motor voltage is
not supplied within 0.08 second.
2. Pump motor voltage is at high level for 2.5 seconds or
more although motor relay does not actuate .
3. Pump motor voltage keeps low level for longer than 0.04
second and the pump repeats activating for 0.7 se-
conds 3 times maximum. At the last time of activation,
the pump motor goes dead because of short circuit.
