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.

INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 if you are using the hand±held tester and start from step 2 if you are not using
the hand±held tester.
1 READ VALUE OF HAND±HELD TESTER(FRONT SPEED SENSOR)
(a) Select the item ºWHEEL SPEED FL (FR)º in the DATA LIST and read the value displayed on the hand±
held tester.
(b) Check that there is no difference between the speed value output from the speed sensor displayed
on the hand±held tester and the speed value displayed on the speedometer when driving the vehicle.
OK:
There is almost no difference in the displayed speed value.
HINT:
There is tolerance of
10 % in the speedometer indication.
OK Go to step 5
