No, the rear sensing system won't signal if you are in any gear except reverse. The wiring for the module is connected so that it turns on when you put the car in reverse. (This assumes the sensors haven't failed. If they are dirty, they can sometimes signal when an object isn't there.) Some newer cars have blind spot monitors that indicate an object approaching from behind and to the side; these don't indicate an object directly behind the car.
hello i would like to help but can you give me information on the sensor kit you installed. some systems to beep and some only beep when the sensors detect something. also if they work fine with out the engine running but then don't work properly when the engine is run this could be there is to muck voltage for the sensors, some sensor kits are saying they are 12v, this is correct 12 volts, but the charging system on most vehicles are 14 volts, so you may have to fit a regulator to the feed wires to the sensor. you would need a 12 volt regulator board. this will stop any power going over the 12 volts to the device.
Try to clean rear parking sensors. Check also electric cables and connections, clean if necessary. Commons faults are sensors out of order. If one or more sensors faults you hear only a continous constant noise when you put in "R" gear. You need a VAS, VAG-COM, Bosch KTS, ... diagnosis scantool. The factory parking system will be scaned from errors with this instrument, and you will find exactly which sensors are out of order (for example: rear left center sensor, rear right side sensor break off, short to ground or short to plus).
the long beep is to tell you its on.try asking someone to walk past when your in reverse about 18 inches from the bumper if it dont beep beep then try cleaning sensors.if that dont work then a sensor could be faulty..
I find the sensors only activate when you are very close to an object behind you. At about 5 inches they beep constantly. Further then five inches they beep slower and slower until they stop at about 8 inches from something behind you. If you are very close to an object lest then 2 inches they will beep constantly. Also when you start your car and put it in reverse and you hear a beep the reverse sensors are not working. The best way to test them is to turn the key to the start position but do not start it. place the lever in R get out or have someone walk in back of the car, you should hear the sensor go off. Also, there might be a situation when one or two are not working. Follow the procedure above for test but have a stethoscope mechanic type, which most auto parts stores carry. and listen to each one individually. If one is not working it will have to be replaced. The control module for this system is in the trunk next to the spare tire. Some of these cars had a leaking trunk problem in 02 if the module is wet, get a new one. If it hasn't failed it will when they get wet. Finally the sensors should be heard inside and outside the car.
There is few options.First-reverse switch not working.How to check-switch ign. ON,select Reverse and check reverse lights at back.If not-change switch.If O.K. go to step two: Disconect reverse sensors next to a bumper and check for resistance/any one/,because all sensors are conected in serie.If there is not resistance check all sensors one by one to find a wrong one.And last one-check "beep" speaker
