"Error 2"

Could be a bug in the HiFi controller. We will look into it. Can you dig out that Bush and send it to me?

Ahhhh....HELL NO !

Could be a bug in the HiFi controller.

Here's something else I remember now-

From my early adoption of the AL-P in 2013 I've always had my Parking "set-point" @ #3 & have never changed it.Early on,only time when I would get the "Proximity" notice was when I was ~3-4ft from an object.The only time I would ever receive a proximity warning earlier (at wider spacing) like ~6-8ft was when behind a highly reflective surface like a P/U chrome bumper or a White/Silver metallic car paint.
Obviously,that told me back then that there is no T.O.F.(Time of Flight) measurement for distance being calculated,but rather an IR "intensity" level feedback is actually being measured which is why that chrome bumper gives a warning at the farther spacing difference.

So that means some measurement parameter has been altered in either the recent f/w 4.5.2 release or it's something in the HiFi controller as you mentioned.


Update -
When returning home this aftetnoon I left the AL-P 'ON' & until parked very close to the lilac bush & no Alert or Error 2 occurred sitting there for 2-3min.Then turned 'OFF' the AL-P...waited ~20sec. & turned it back 'ON' & got an immediate Error 2 w/ same conditions as described in previous Post earlier.
Appears that the 1st IR pulse output at turn-on may have increased photon energy output causing objects return signal to indicate it's much closer than it really is.

Put the heads back to F1 & F2, did a factory reset and the heads continue to give Error 2 prompts at the same spots in my morning commute. Pulled stats immediately after error 2 codes came up as I know where to expect them during my morning commute. Stats stated no error with F1 or F2. I hypothesized it has to do with the position of the sun in relation to the heads. It seems to occur when the sun is directly in front of me. I tested my theory by finding a stretch of interstate which put me directly in front of the sun. This resulted in an Error 2 code until i turned. I drove that same stretch of road in the evening multiple times with no error 2 codes. I never had these problems when the ALP was 1st installed. Additionally, this problem did not occur with the LI's that i was previously using (not speaking negatively of the ALP). I do not have the Hifi module. My setup currently is all stock with laser defense and the Error 2 codes continue to occur. I do not wish to be at a disadvantage or have the error occur when I am the target LEO. Please advise on how to resolve. My ALP is HW version 2 received it Dec. 2014.

"If they get error 2 sometimes, it can be because of strong IR pulse source like car equipped with LCC, various sensors etc ."

We will look into this more but if its happening in the same location there is some sort of IR pulse that the AL does not recognize. Instead of ignoring it its defaulting to an error message.

I may be doing a poor job articulating myself. It is not at just a certain location as the stretch of straight highway that I drove down to test my sun theory is not in my morning commute. It gave the Error 2 message the entire time when I was directly facing the sun during this test. (This did not occur with my previous jammers) During my morning commutes, there are certain locations that I am in the direct path of the sun, that is when the error 2 message occurs. I cannot alter the movement of the sun obviously, but do not need to be exposed due to a possible defect in my hardware as it seems I may be the only experiencing this particular issue. I have a 2008 Maxima; no LCC, no park assist, no blind spot monitoring, etc. Unfortunately, I do not have sufficient privileges to post pictures of my install for evaluation, however it was meticulously setup for optimal performance. Heads are as level as possible, and wires are routed for minimal electrical disturbances from the car.

Photos of my install in-case it may help diagnose the problem.

My error 2, F1 and sensor fails started before I uploaded the wifi software and continue with the wifi software. I was running the droid module without any issues for several month than all the issues started. I did notice the different warnings between software. It is unplugged right now because my system is DOA. Not useable in its current state.

Tom, is it possible that maybe the sensor is getting a high reflection from the bottom part of the bumper?

Ballaz, I'm no expert, but I want to throw some ideas out in case something sticks. Unless BRD or anyone else tells you not to try this, do you have a (not shiny) black flat card or something else dark that you can place directly below the heads that will stick out about 2" pass the bubble? I am curious about this because from looking at the photos, the edge of the bottom bumper has a nice reflection. It's a long shot, but it wouldn't hurt to try. I say this because if your indicating that it happens when traveling in the direction of the sun, then it sounds like to me that your getting an array reflection from something. Just a thought, I am very curious as to what is causing your problem also.

One more thing to consider.... It's probably not it BUT, I was getting errors, and come to find out I had a bad power connection, because the unit eventually just started powering off. After I fixed this, things have been fine and no more errors.
