- Is the result within specifications?
YES
- Replace it with a new ESP (ESC) and check for proper operation. If problem is corrected, place the new ESP (ESC) and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE: * In a case of replacing ESP (ESC), perform following functions- "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 )
NO
- Check for open or blown fuse referring to "Circuit Diagram".
- Repair open or short in power circuit between battery and ESP (ESC) harness connector and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Repair open or short in ground circuit between battery and ESP (ESC) harness connector and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
