The object sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The parking assist control module supplies 8 V to the object sensors via the 8 V reference circuit and provides ground via the low reference circuit. The parking assist control module triggers the sensors in a sequential loop. After each sensor transmits, the parking assist control module uses the sensor echo received through the signal circuit to calculate the distance and position of an object.
| • | Ignition ON |
| • | The parking assist is activated. The activation takes place through putting in the reverse gear or through operating the parking assist switch. |
The advance parking assist control module has detected the 8 V reference circuit is less than 7.2 V.
The advance parking assist control module has detected the 8 V reference circuit is greater than 9.2 V.
| • | The parking assist is disabled. |
| • | The cluster displays service park assist symbol. |
The condition for setting the DTC is no longer present.
Object Detection Description and Operation : C140/Long Body UFR or UD7 → C145/Short Body UFR → Rear Vision Camera → Holden Genuine Accessory(Aftermarket)
Control Module References for scan tool information
Ignition ON, activate the parking assist, observe the scan tool Park Assist Sensor Reference Voltage parameter. The reading should be between 7.2-9.2 V.
| ⇒ | If less than the specified range, test the 8 V reference circuit for a short to ground. If the circuit tests normal, replace the K86 advance parking assist control module. |
| ⇒ | If greater than the specified range, test the 8 V reference circuit for a short to voltage. If the circuit tests normal, replace the K86 advance parking assist control module. |
| ⇒ | If the DTC is set, replace the object alarm sensor that was connected immediately before the DTC set. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
| • | Front and Rear Object Alarm Module Replacement : With UFR → With UFR and UD7 |
| • | Rear Parking Assist Alarm Sensor Replacement : Short Body → Long Body |
| • | Control Module References for advance parking assist control module replacement, programming and setup |
