Testing PDC sensors

Think I know the answer to this. A Big Fat NO. But anyway of checking if parking sensors are good before fitting to the car and not having sensors activated? Can you bell them out?? I brought a set of sensors and other front bumper parts of eBay a few months ago. About to remove bumper and fit everything before getting Bodsy to activate sensors. Just want to check they're all good and not find I've fitted faulty sensors meaning I have to take the bumper back off

Cheers
Nick

No, don't think so.

Worth be worth checking out there is no short between the power pins, black & brown.

Other than that, when they are activated it should be easy to locate any faulty sensors (as long as the above check has been done)

Before installing the bumper, plug them in to the wiring harness. Put the key in the ignition, just before the start position (don't start the truck). Select reverse gear. The parking brake has to be off. Put your ear to each sensor. A functioning sensor will emit a faint clicking sound. If not, could be the wiring is damaged, or the sensor is out. LR3 - 2005 Java Black SE 4.4 V8

You can use an ohm meter on the three pins and look for the same readings on each unit, the fronts have a different value to the rears. I have used this to find faults when the car only shows the fixed light and no error codes the faulty one had different resistances.

fronts and rears should be the same.
Maybe just a different manufacture

Probably the same check as I suggested.
