Automatic check failed

Dear BestRadarDetectors,

When the ALP starts, it says "Automatic check fail R1". I get this stats:

I reversed the 2 rears sensors, and I get this:

Do you confirm that one sensor is broken?

Thank you very much.

NB: I still have to update the voice pack.

Sounds like to me the sensor has gone bad!

Either a sensor has failed or a cable has been compromised. If you can get to the sensor connectors in the rear and move the working sensor to the other sensors wiring you can determine if the cabling or the sensor is bad.

Hello, I found that the sensor which wrong, I've disconnected it and I let the 1 which is OK on R1 position. When the CPU starts, it says 'Automatic check failed: R2 F2'

When I connect only one sensor, the defective sensor to R1, I get this 'Error 2 defective sensor'

Is the CPU box is wrong as well?

You might have a bad cable and not a bad sensor. What you need to do is reconnect both sensors and see which sensor is online. Then take the other sensor the one showing an error (Disconnect it from the wiring connector at the sensor) and try that head on the working sides cable. If you just move the sensors from one port to the other you are still using the same cable.

When you did this check, where did you make this change ? Did you swap the cables R1 & R2 at the Control Box ?

When you did this check, did you leave the cables the same from your 1st Test above & make the cable swap at the connectors near the Sensors.

You need to take a more methodical approach to EXACTLY what & where you are changing things to help us understand the details to figure out the problem.

I have reversed the 2 plugs (the round twisted plugs without disconnecting the 2 RJ), both are connected to R1 and R2. In one position, I've the error R2 and F2, when reversed, I get R1, R2, F2 errors. I don't understand why for F2, nothing is connected.

Same thing I reverse the RJ plugs. So it's not the cable. Either the CPU, either a sensor.

Now, I use the front CPU, I've connected these 2 sensors on F1 and F2. I get the "Uboat" song (I don't have it with the rear CPU) at the startup, no error message, the right sensor doesn't work as parking sensor, the left works well. But both detect my laser tester. I have the same results when I reverse the 2 rounds plugs of the cables.

I think my right sensor and the rear CPU are wrong. Do you agree?

Thanks.

You are very confusing...your English translation & poor syntax is very difficult to understand.

What is your native language that you speak ?

1.There are NO U-boat songs...do you actually mean U-boat sound ???
2.Do you only have 2 AL-P Sensors & both are installed on the Rear of your car ?

I'm French native speaker.

1) I use the optional ALP speaker. The 'music' at the start of the ALP is a kind of 'beep beep beep' as a U-boat submarine. I hear it at start if there is no error (with the front CPU and the 2 rear sensors).
2) I have a CPU for front (2 sensors) and the faulty rear CPU for the rear (2 other sensors). I have tested the 2 rears sensors with the front CPU as reported.

Ok, now I understand that you have 2 separate ALP systems, each with 2 Sensors.
In the beginning, the Front system was ok...correct ?

It was only the Rear system that was bad...correct ?

Do you want to start over by putting everything back to its original condition.- This way we can try to solve the problem you are having on the Rear.
You should not be getting U-boat "ping" sounds...make sure there are no objects close to the Rear Sensors & turn OFF power to the Front system.

Can I ask why you are using 2 CPU'S instead of one CPU with the 4 sensors attached?

I thought the same thing Tom, but didn't want to confuse things anymore than they already are.
Just want to solve his problem first !

The front system works well with the front sensors. When connected to the rear sensors, no error message but only one sensor works as parking sensors. But both detect my laser tester. I have the same results when I reverse the 2 rounds plugs of the cables.

The back system works wrong: error message in any positions of the sensors. In one position, I get R2, F2, R1 are not OK (only R1, R2 are connected). When I reverse the cables, I get R2, F2 are not OK (only R1, R2 are connected).

All systems are in position. The back system doesn't work as just explained above.

I have 1 CPU + 2 sensors and another CPU + 2 sensors. I didn't try to connect the 4 sensors to the same CPU. Probably the cables are too short.

This does not make sense...when you swap cables, where are you doing it ? At the RJ Ports or the Twist connector near the Sensors ?

You should not be getting an F2 error unless you made a mistake at the RJ Port & plugged into the F2 Port.

---

If you have these errors I'm starting to think you have inter-mixed the Front/Rear cables w/ each other & in combination of also having a bad Sensor this could be the only reason Port F2 is appearing as an error in both conditions.

@syrinx
I am leaving Forum for now to have Dinner meal w/ my Wife. I will return later to see how you are doing w/ the problem.

Here I've swapped step by step the twist connectors, tested again. Never something was plugged in the F2 port, never.

Nothing was plugged in F2 port. The front cables can't reach the rear CPU.

Honestly I am still confused what you are doing and why you have 2 CPU'S with only 4 sensors.

I believe he may have at some point incorrectly put one of the Rear RJ plugs into the F2 port(by mistake) & did a "Memorize" option & now the CPU Control Box thinks it has gone bad b/c there's no Sensor connected.

As he stated previously, he has 2 independent b/c the cables from the Rear were not long enough to reach the Front Control Box. Why he didn't just relocate the Front Control Box to somewhere in the middle of the cabin (under the Driver seat) so that Front & Rear sensors cables could both reach it isn't something that was considered, I guess.


Attention: @syrinx -
Would you be willing to start over again from the beginning by putting the Rear ALP system back to its original wiring connections from when your Errors were first starting.
1. Also, I would ask you to put "labels" (for R1,R2) marking EACH side of cable, put labels on each RJ "plug" connection at the Control Box.
2. Put labels(R1,R2) on each side of round "twist" connectors.
3. Put label on each Control Box port (R1,R2) to prevent using F1,F2,F3 by mistake.

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.

If he is willing to do as you suggest I am fine with stepping aside & let the both of you work together to identify whether it is the Sensor or the cable wire that is the problem.

Good Luck. :thumbs2:

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.

syrinx, You should have purchased two of the "AL Priority Sensor Extension Cables" @ $29.95 USD each. Then you would have been able to connect the two rear ALP sensors to one ALP CPU, to which the two front ALP sensors are connected.

(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 !)

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.

With my hand, I see that one sensor doesn't work as parking sensor.

With the laser tester, I've hidden one by one the sensor with à piece of paper.

I will try again because I did already this factory reset and I didn't see any improvement: same errors message with F2 which wasn't never used.

I don't understand your idea, I don't want cables between front and rear of the cars. I can hear the front, I can hear the back, I don't have cables in view, it's what I want.

With the laser tester, I've hidden one by one the sensor with à piece of paper.- Paper does not completely block Infrared photons, some can still pass through & some will scatter for the other sensor to receive & will cause alert. The AL-P sensors are very,very sensitive to receive a small amount of IR signal from the Tester.

1. Did you label the cables like I asked you to do ?
Just as you posted before when you started this Thread, what were the results you got when you looked at the ALP report like in your Post #1 ?

Hello,

Thank for the factory reset. I succeed to do it. The CPU behave well now (I mean no error on a port which was never connected, used).

The cables have been labelled from the beginning. When I reverse the round ports, or when I reverse the RJ ports, I have always the same result: the right rear head is not working in parking mode, it detects my laser tester but it doesn't emit. It makes sense with the parking mode which is not working. I will dismount this head and send it for guarantee exchange.

Thank you very much for your support! The mess was from the CPU which was needing a factory reset.

You're welcome, congratulations on finding your problem & getting it fixed.

No answer from Radarmeister/Hugel66 for few weeks. Where can I send my dead sensor (from Europe)? Thanks.

Contact the dealer who you purchased from. I am sure they must have a phone number.
