Signal Waveform
Inspection 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable. 2. Disconnect the fuel pressure regulator valve connector.
Description To sense the cars exactly in the next lane with the radar, the direction of the sensor and the direction of the vehicle have to align. This is BSD unit alignment. If this alignment is not performed as below illustration, the degradation of detection performance and the cause of false alarms.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Recover the refrigerant with a recovery/ recycling/ charging station. 3. When the engine is cool, drain the engine coolant from the radiator. 4. Remove the expansion valve cover (A).
