Circuit/System Description
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.
Conditions for Running the DTC
* Ignition ON
* The park assist is activated. The activation takes place through putting in the reverse gear or through operating the park assist switch.
Conditions for Setting the DTC
B0954 01, B0955 01, B0956 01, or B0957 01
The parking assist control module has detected the voltage at the sensor circuit is greater than 11.5 V or the object sensor is not grounded.
B0954 06, B0955 06, B0956 06, or B0957 06
The parking assist control module has detected the voltage at the sensor circuit is less than 0.5 V.
B0954 08, B0955 08, B0956 08, or B0957 08
The parking assist control module has received an invalid signal.
B0954 21, B0955 21, B0956 21, or B0957 21
The object sensor determines no change in the position of an object while the vehicle is in motion.
B0954 3A, B0955 3A, B0956 3A, or B0957 3A
The parking assist control module determines the wrong sensor type is installed.
Action Taken When the DTC Sets
* The parking assist is disabled.
* The driver information center displays SERVICE PARK ASSIST.
Conditions for Clearing the DTC
The condition for setting the DTC is no longer present.
