瀚慖f greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K41



Parking Assist Control Module.



3. Ignition ON, activate the park assist, test for 7.5-9.0 V between the 8 V reference circuit terminal 1 and ground.



瀚慖f less than the specified range, test the 8 V reference circuit for an open/high resistance. If the circuit tests normal, replace the K41



Parking Assist Control Module.



4. Ignition OFF, remove the malfunctioning object sensor and swap locations with another properly functioning front object sensor. Connect the



harness connector at both sensors.



5. Ignition ON, verify the DTC is set for the new location in which the malfunctioning sensor is installed.



瀚慖f the DTC does not set for the new location, test the signal circuit terminal 3 for a short to voltage, short to ground, or an open/high



resistance. If the circuit tests normal, replace the K41 Parking Assist Control Module.



6. If the DTC sets for the new location in which the malfunctioning sensor is installed, replace the appropriate front object sensor.
