INSPECTION PROCEDURE
1 RECONFIRM DTC
HINT:
This code is detected when a problem is determined in the brake actuator assy.
The solenoid circuit is in the brake actuator assy.
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check
if the DTC code is output before replacing the brake actuator assy.
(a) Clear the DTCs(see page 05-765).
(b) Turn the ignition switch to the ON position.
(c) Are the same DTCs recorded?
NO PROCEED TO NEXT CIRCUIT INSPECTION
SHOWN IN PROBLEM SYMPTOMS TABLE
(SEE PAGE 05-786).
YES
REPLACE ABS & TRACTION ACTUATOR ASSY (SEE PAGE 32-37)

CIRCUIT
DTC C0274/14 SHORT CIRCUIT IN ABS MOTOR RELAY
CIRCUIT
DTC C1361/91 SHORT CIRCUIT IN ABS MOTOR FAIL SAFE
RELAY CIRCUIT
CIRCUIT DESCRIPTION
The VSC motor relays consist of 2 relays are included in the ABS R/B.
The VSC cut relay is turned on after turning the ignition switch to the ON position. If the DTCs in the
ABS pump motor circuit are memorized, the VSC cut relay cuts off the power supply to the VSC motor
relay and performs the fail safe.
While any of the ABS, BA, TRAC and VSC is operating, the skid control ECU (included in the actuator)
turns the VSC motor relay on to operate the actuator pump motor.
If the voltage applied to the VSC motor relays (+BM) drops below the condition that detects the DTCs
due to the shortage of the battery or alternator output, the DTCs may be memorized.
