Open in ABS Solenoid Relay Circuit

DESCRIPTION

This relay supplies power to each ABS solenoid.

Immediately after the ignition switch is turned to the ON position, the relay turns on if the solenoid is determined to be normal as a result of self-diagnosis during initial check.

The relay turns off if an open/short is detected.

If the voltage supplied to the motor relay (+BS) is below the DTC detection threshold due to low voltage from the battery/alternator, the DTCs may be stored.

WIRING DIAGRAM

Refer to DTCs C0226/21, C0236/22, C0246/23 and C0256/24 (See page BC-29).

INSPECTION PROCEDURE

1 INSPECT FUSE (ABS 2 FUSE)

(a) Remove the ABS 2 fuse from the FL block.

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance

2 INSPECT SKID CONTROL ECU (+BS TERMINAL VOLTAGE)

INSPECT SKID CONTROL ECU (+BS TERMINAL VOLTAGE)

(a) Install the ABS 2 fuse.

(b) Disconnect the skid control ECU connector.

(c) Measure the voltage according to the value(s) in the table below

Standard voltage

3 INSPECT SKID CONTROL ECU (GND TERMINAL CONTINUITY)

 INSPECT SKID CONTROL ECU (GND TERMINAL CONTINUITY)

(a) Measure the resistance according to the value(s) in the table below.

Standard resistance

4 RECONFIRM DTC

(a) Clear the DTCs (See page BC-10).

(b) Start the engine.

(c) Drive the vehicle at the speed of 6 km/h (4 mph) or more.

(d) Check that the same DTCs are recorded (See page BC- 10).

HINT:

  • Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.
  • If a speed signal of 6 km/h (4 mph) or more is input to the skid control ECU, with the ignition switch on and the stop light switch off, the ECU performs selfdiagnosis of the motor and solenoid circuits.

Result

HINT:

  • If any DTCs are output while jiggling a connector or wire harness of the brake actuator (skid control ECU), inspect and repair the connector or wire harness.
  • If the normal system code is output, slightly jiggle the connectors, wire harnesses, and fuses of the brake actuator assembly. Make sure that no DTCs are output.
  • These DTCs may be memorized due to a malfunction in the connector terminal connection, etc.
