I personally think he needs to connect one CPU with 2 front sensors, 2 rear sensors. Run a factory reset and start all over with troubleshooting.

I bought 2 CPU because I don't want cables inside the car from the front to rear of the cars. It was working few months like this.

How do you do a factory reset? I tried but it doesn't seem to work.

Please remember that at least one sensor is broken:

With front system used with the rear sensors: when connected to the rear sensors, no error message but only one sensor works as parking sensors. But both detect my laser tester.

syrinx, "IF" you did not want sensor cables inside your car and/or the original/standard cables were not long enough to reach from the ALP CPU (most likely placed under your dash) to your rear ALP sensors, you should have ordered two of the "AL Priority Sensor Extension Cables" @ $29.95 USD each.

(If 1 Sensor or 1 bad cable, the CPU Control Box may not permit a Factory Reset...I have never tried this w/ a problem existing in the system already !)

Instructions are already here on the Forum if you would look for them !

Ok, we can use this, but don't use the Laser Tester,the output is to wide & not useful to draw conclusions for which sensor or cable is the bad one.

Use your hand instead- by placing it close (about 10mm) to each one, see if you get U-boat "ping" sound from each Rear sensor.
