- After connecting GDS, check DTC on the GDS.
- Using GDS, Erase the DTCs.
- Using a GDS, Check DTC present.
- Is the same DTC shown?
YES
- Substitute with a known-good IBAU and check for proper operation. If problem is corrected, replace IBAU and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Fault is intermittent caused by poor connection in IBAU harness or faulty IBAU. Go to "VERIFICATION OF VEHICLE REPAIR " procedure
NOTE:
* In a case of replacing IBAU, perform following functions
- "Brake Pedal Travel Sensor Calibration" for brake pedal sensor offset correction (refer to C138004 )
- "Pressure Sensor Calibration" for pressure sensor offset correction (refer to C138404 )
- "Steering Angle Sensor Calibration" for steering angle sensor offset correction (refer to C126104 ) -ESP (ESC) only
- "Longitudinal Sensor Calibration" for Longitudinal sensor offset correction (refer to C128504 ) - ESP (ESC) only
- "Variant Coding" for option coding (refer to C170204 )
