sensor. If possible move the sensor so it is not detecting the object(s). If it is not possible to
relocate the sensor, then consult the factory.
If for some reason the system is malfunctioning, all of the LED’s (yellow and green) will be
flashing and the buzzer will be sounding. Refer to the Error Indications and Troubleshooting
sections below to determine the error and solution.
Once the system has been installed, the detection zone should be tested. Testing is
accomplished by using two individuals. One individual is engages the parking brake,
depresses the vehicle brake, and places the vehicle in reverse. The other individual then
walks through the detection zone noting where the display buzzer or the back up alarm
activates. By moving about the rear of the vehicle and noting when the display or back up
alarm activate, an accurate detection zone can be mapped.
