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 is activated, 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. Pump motor voltage is 2.0 V or more for 1 sec. or more
at motor relay OFF.
2. Pump motor voltage is (IG ± 4.0 V) or less for 0.1 sec. or
more at motor relay ON.
3. After the end of the actuation of the motor relay slow
down condition of motor does not meet the specification.

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 PERFORM ACTIVE TEST BY HAND±HELD TESTER(ABS MOTOR RELAY)
(a) Check the operation sound of the ABS motor individually when operating it with the hand±held tester.
OK:
The operation sound of the ABS motor is heard.
OK IF THE SAME CODE IS STILL OUTPUT AFTER
THE DTC IS DELETED, CHECK THE CONTACT

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.
1READ VALUE OF HAND±HELD TESTER(REAR SPEED SENSOR)
(a)Select the item ºWHEEL SPEED RL (RR)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.
OKGo to step 5
