ST ANGLE SEN CIRCUIT

Is the "ST ANGLE SEN CIRCUIT" display?

YES: GO TO 3.

NO: INSPECTION END
CHECK CONNECTOR
1. Turn ignition switch "OFF".
2. Disconnect steering angle sensor connector M33 and ABS actuator and electric unit (control unit) connector E24 and check terminals for deformation, disconnection, looseness, and so on. If there is an error, repair or replace terminal.
3. Reconnect connectors and perform an ABS actuator and electric unit (control unit) self-diagnosis again.
OK or NG

OK: INSPECTION END

NG: GO TO 4.
CHECK STEERING ANGLE SENSOR CIRCUIT
1. Turn ignition switch "OFF".
2. Disconnect steering angle sensor connector M33 and ABS actuator and electric unit (control unit) connector E24.
3. Check continuity between ABS actuator and electric unit (control unit) connector terminal and steering angle sensor connector terminal.
  11 - 4: Continuity should exist.
  
  15 - 5: Continuity should exist.
