Code B1299 RAM Description

The Park Assist Sensors (PTS) are ultrasonic transceivers that are completely controlled by the Park Assist Module. The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return the circuit to the module. The sensors communicate with the Park Assist Module using a dedicated serial bus communication circuit. The Park Assist Module monitors the PTS Sensor when the vehicle in reverse and during the self-test while the vehicle is in drive between 18 km/h (11 mph) and 40 km/h (25 mph). The Park Assist Module sets the OBDII code when the Park Assist Sensor Signal circuit is not to factory specifications.
