Dtc Diagnosis Procedure

DTC Diagnosis Procedure

CHECK CONNECTOR
1. 1. Ignition switch OFF.
  2. Check the ABS actuator and electric unit (control unit) harness connector for disconnection or looseness.
  3. Check the chassis control module (with built in steering angle sensor) harness connector for disconnection or looseness.
  4. Check the chassis control module (with built in steering angle sensor) harness connector for disconnection or looseness.
Is the inspection result normal?
YES >>
GO TO 3.
NO >>
Repair / replace harness or connector, securely lock the connector, and GO TO 2.
PERFORM SELF DIAGNOSTIC RESULT
1. CONSULT

Is DTC “C106E-01” detected?
YES >>
“CRNT” is displayed: GO TO 3.
NO >>
Inspection End.
CHECK TERMINAL
1. 1. Ignition switch OFF.
  2. Disconnect the chassis control module (with built in steering angle sensor) harness connector.
  3. Check the chassis control module (with built in steering angle sensor) pin terminals for damage or loose connection with harness connector.
  4. Disconnect the chassis control module (with built in steering angle sensor) harness connector.
  5. Check the chassis control module (with built in steering angle sensor) pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES>>
GO TO 4.
NO>>
Repair / replace harness, connector, or terminal.
CHECK CAN COMMUNICATION LINE
1. 1. Connect chassis control module (with built in steering angle sensor) harness connector.
  2. Connect chassis control module (with built in steering angle sensor) harness connector.
  3. Check the CAN communication line. Refer to Trouble Diagnosis Flow Chart.
Is the inspection result normal?
YES >>
GO TO 5.
NO >>
Repair / replace harness or connector.
CHECK DATA MONITOR
1. CONSULT
  1. Select “ABS”, “Data Monitor” and “STR ANGLE SIG” according to this order.
  2. Check that the indication changes with the steering angle when the steering wheel is turned left/right from the neutral position. Refer to Values On The Diagnosis Tool.
Is the inspection result normal?
YES >>
Replace the ABS actuator and electric unit (control unit). Refer to Removal and Installation.
NO >>
Replace the chassis control module (with built in steering angle sensor). Refer to Removal and Installation.
