Power & Ground circuit Inspection

Item	Normal Value	Prerequisite Condition	Probe (+)	Probe (-)
Power circuit (open/short): Voltage	Battery voltage	Ignition switch: On	ESP (ESC) power (+) terminal	Chassis ground
Ground circuit (open): Resistance	Below 1.0Ω	Ignition switch: OFF ESP connector: Disconnected	ESP (ESC) ground (-) terminal	Chassis ground

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
1. "Steering Angle Sensor Calibration" for steering angle sensor offset correction (refer to C126104 ) -ESP (ESC) only
2. "Longitudinal Sensor Calibration" for Longitudinal sensor offset correction (refer to C128504 ) - ESP (ESC) only
3. "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.
