INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT
(a) Clear the DTCs Advanced Parking Guidance System.
(b) Check for DTCs Advanced Parking Guidance System.

Result





HINT: Even if this DTC is output, steering angle control is performed (only hybrid vehicle control is not performed).

C -- USE SIMULATION METHOD TO CHECK
B -- GO TO ELECTRONICALLY CONTROLLED BRAKE SYSTEM
A -- Continue to next step.
2. PERFORM G SENSOR ZERO POINT CALIBRATION
(a) Perform the G sensor zero point calibration Programming and Relearning.
NEXT -- Continue to next step.
3. CHECK DTC OUTPUT
(a) Clear the DTCs Advanced Parking Guidance System.
(b) Check for DTCs Advanced Parking Guidance System.

Result





C -- END (YAW RATE SENSOR ZERO POINT CALIBRATION IS INCOMPLETE)
B -- PERFORM G SENSOR ZERO POINT CALIBRATION
A -- REPLACE PARKING ASSIST ECU
4. PERFORM G SENSOR ZERO POINT CALIBRATION
(a) Perform the G sensor zero point calibration Programming and Relearning.
NEXT -- Continue to next step.
5. CHECK DTC OUTPUT
(a) Clear the DTCs Advanced Parking Guidance System.
(b) Check for DTCs Advanced Parking Guidance System.

Result





B -- END (YAW RATE SENSOR ZERO POINT CALIBRATION IS INCOMPLETE)
A -- REPLACE PARKING ASSIST ECU
