The object sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The object alarm module supplies 8 V to the object sensors via the 8 V reference circuit and provides ground via the low reference circuit. The object alarm module triggers the sensors in a sequential loop. After each sensor transmits, the object alarm module uses the sensor ring received though the signal circuit to calculate the distance and position of an object.
• | Ignition ON |
• | The parallel parking assist is activated. The activation takes place through operating the parallel parking assist switch. |
The object alarm module has detected the voltage at the sensor circuit is greater than 11.5 V.
The object alarm module has detected the voltage at the sensor circuit is less than 0.5 V.
The object alarm module has received an invalid signal.
The object sensor determines no change in the position of an object while the vehicle is in motion.
The object alarm module determines the wrong sensor type is installed.
• | The parallel parking assist is disabled. |
• | An indicator in the driver information center shows the parking assistance is not available. |
The condition for setting the DTC is no longer present.
Object Detection Description and Operation
Control Module References for scan tool information
⇒ | If DTC is present, refer to DTC B138A. |
⇒ | If DTC is present, replace the appropriate sensor with a sensor by correct sensor type. |
⇒ | If DTC is present, check the appropriate sensor for contamination with mud, ice or snow. If no contamination is diagnosed, replace the sensor. |
⇒ | If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K41 Object Alarm Module. |
⇒ | If less than the specified range, test the 8 V reference circuit for an open/high resistance. If the circuit tests normal, replace the K41 Object Alarm Module. |
⇒ | If 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 Object Alarm Module. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
