Cleaning Sensors
One of the best things that you can do for your sensors is keep them clean. Most of the time, whenever there are
any issues with the reverse parking sensor, it is because gunk from driving has settled over it. Fortunately, cleaning
it is a simple task that can be done quickly and is usually very effective. Clean them with a soft cloth or rag. There
may be dirt and debris trapped on them or they may be oily or dusty. Cleaning with a pressure washer can cause
issues and it is advised not to directly spray parking sensors.
Checking a sensor is working
First, switch on the PDC (Park Distance Control). With this one, get as close as you can to the sensor and put your
ear near it. Listen to see if there is a buzzing sound. If there is, then the sensor itself is working. If you cannot hear
anything or if you do not want to put your ear that close to the sensor then you can simply put your finger up
against it. If the sensor is vibrating or clicking just slightly then they are working.
Not detecting some objects
Some objects are harder to detect than others. Objects that have an angle or are round may cause the ultrasonic
sound-wave to deflect away and not return a signal to the detector heads. Absorbent objects may also not detect
as well. If you think an object should be detected check the sensors are working correctly.
Front parking sensors not activating on CANBUS system below 6mph
Check PSPK1 CAN module is working correctly.
NO LED - Incorrectly Connected.
RED LED - System is not connected to CAN or active and cannot identify the vehicle.
CONSTANT GREEN - Connected to CAN.
FLASHING GREEN - Speed pulse detected.
Handbrake - Check handbrake is off. Having the handbrake on can often override the PSPK1 and prevent it
triggering the parking sensors.
Important:
Troubleshooting can only be done with the RUI interface in most cases available from Parksafe
Automotive. Parksafe Automotive can offer technical support and access to the latest software through the RUI
interface.
