Hi ,new here and just looking for some info .i have a problem with the parking sensors on my 2011 rcz.tried the wd40 trick to no avail and also listened for the clicking and none of the sensors seem to be responding .four to the front and four to the rear .I have tried to locate the ecu which i believe should be in the boot to the left hand side but not there.Can anyone point me in the right direction,thanks
