Parking sensor issues ft. Loose shark fin
Hey all,
Just wondering if any of you mechanically minded folk would be able to help me diagnose an issue I've been having with my CR-Z.
Issue description
I've had an intermittent issue with the rear parking sensors over the last 2 years - potentially caused by water ingress and became intermittent during hot and cold weather.
In the last 6 months when turning the car on (with the parking sensor button turned on) it comes up with a "Check system" and a picture of the rear of the car and sensors.
When the button is turned off - the message & warning light goes away.
Fix attempt & further investigation
I noticed the LED on the button itself had blown, and after replacing it the light works again (hurray!) but the check system message pops up.
I've taken the rear bumper off, removed the the sensors and cleaned them and tested them - same thing.
I have noticed the rear of three of the connectors have cracking on the soft rubbery plastic part which potentially may have let water inside.
However... when all sensors are disconnected the image on screen shows check system and all 4 sensors. When all sensors are connected the image on screen shows check system and only the far left and far right.
Self hypothesis
I've determined the next step and resolve for the issue is to replace the two sensors displaying with the issue message. Would you agree?
Also my shark fin cap has come loose - so I think I just need some silicone sealant and effectively glue it back down if I remember correctly?
Ta!
