Circuit/System Verification
1. Verify that DTC B1405 is not present.
瀚慖f DTC is present, refer to DTC B1405 (See: B Code Charts/B1405/Object Detection).
2. Verify that DTC B0954 01, B0955 01, B0956 01 or B0957 01 is not present.
瀚慖f DTC is present, check the appropriate sensor for contamination with mud, ice or snow. If no contamination is diagnosed, refer to
Circuit/System Testing.
3. Verify that DTC B0954 21, B0955 21, B0956 21 or B0957 21 is not present.
瀚慖f DTC is present, check the respective sensor for contamination by mud, ice or snow. If no contamination is diagnosed, replace the
sensor.
4. Verify that DTC B0954 3A, B0955 3A, B0956 3A or B0957 3A is not present.
瀚慖f DTC is present, replace the respective sensor with a sensor of correct sensor type.
5. Ignition ON, transmission in REVERSE, verify the scan tool Parking Assist System Status parameter displays Enabled.
Circuit/System Testing
1. Ignition OFF for 30 s, disconnect the harness connector at the appropriate front object sensor.
2. Test for less than 5 ohm between the low reference circuit terminal 2 and ground.
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.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
