Default Laser falsing, how to isolate the cause and solve

Issue: Some customers get a laser warning with rapid acceleration.
There are two known things that can cause this:
a) Noisy 12V DC line
b) Radiated signal from vehicle that is coupling onto the front/rear shifter wires.
c) In some cases we have seen that both 1 & 2 apply

Recommended Course of action:
The first step is to determine whether the issues is coming from a noisy DC line or whether a vehicle generated RF signal is being radiated onto the shifter wires.

Finding the source:
1) Isolate power from the vehicle - This can be done with a 12V gel cell. Please make sure that both POWER and GROUND have no connection to the vehicle and are only running off of the gel cell. Re-test with rapid acceleration.

2) If the unit no longer falses, then you know there is a significant source of noise of the 12v DC line. If the unit still falses, then go to step 3.

Things to try would be:
a) Re-route Power AND ground to a quieter line (FM radio lines work well if accessible) - 12 volt accessory plug would be another common option.
b) Install the Escort power filter*.

3) Radiated coupling into shifter wire lines - This can almost always be solved be a re-route of the front and/or rear shifter wires. Some things to keep in mind:
First, note on the display whether the false is coming from the Front or Rear shifters:

Front Shifter Error - Keep shifter wires as far apart from any vehicle "modules" and pre-existing wiring as possible. If you have the wires running down the driver side of the engine compartment, move them to run along the passenger side instead. For testing purposes, lay the wires in the approximate final location and use a couple of tie wraps to secure temporarily. Use extreme caution to make sure that the wires are secure and cannot become tangled in any pulleys or belts.

Rear Shifter Error - Several vehicles have electronically "noisy" fuel pumps mounted in the tank. Running a shifter wire across the tank can be problematic. Run the wires down one side or another (as close to the edge of the vehicle as possible)

If you have been through all of the above steps and the issue still exists, keep in mind that there have been a few cases that have required a better power and ground location, a power filter* and rerouting of the shifter wires to finish the install. If all steps fail, the shifters will need to be sent in for inspection.

* the Escort power filter (aka RF Filter) mentioned above is available by calling us at the number in my signature below, it's price is $35.00 including shipping to the continental US.

This is an old post and it should be updated.

In more current posts in the forum, Laser falsing has also been observed when going by larger airports (owing to wind-shear LIDAR detection devices that are required by the FAA) and also when the sun is low on the horizon, and the detector/shifters are going in-and-out of light, such as when driving along the highway and passing by fencing through which the sun is shining.

Finally, some vehicles have proximity warning systems that use Laser, and these, too might trigger a false alert as you approach them while driving.

Exclamation 9500ix and zr3 issues with false laser reports more and more often

I get false laser warnings driving by Ohare airport every time. Question is why doesnt the radar software recognize this and elminate the same false reading I get every time.

is there a function to disable false laser warnings (such as there is to double tap mute and lock out false radar warnings)?

I also get fasle laser warnings when I slam on my brakes (only happened a few times in 5 years) and also When I honk the horn at high speed it always gives off a false laser that is unwanted and alarming which is a bad thing.

how to fix this ?


I also have recently had multiple false laser warnings lately just driving around and sitting still in parking lots.

"returning" the shifter is not an option, I already spent a ton of money on it years ago.

I currently have a fully updated Passprt 9500ix and ZR3.

I also have all three detectors mounted on the front bumper (I have a hummer h3 and couldnt install the rear one in the rear)

any issues with this maybe ?

thanks !

AFAIK, there are no means of locking out Laser alerts or Ka signals, whether they are false or real.

Perhaps this could be done in a future release, but I don't think that this can be done in any of the current products.

You can lock out laser alerts on the 9500ix, even with a ZR3/ZR4 connected to it, by pressing the mute button 3 times when receiving a laser alert.

That's good information to know! Thanks!

I get a ZR 4 rear laser alert on my 2011 Nisan Murano convertible when I activate the trunk release solenoid. It's obvious what is causing it. I occasionally get a front alert at highway speeds but no alert on the unconnected 9500ix. Could this be from another car's proximity detection system? I overtake and pass many cars on I65 in Alabama. I appreciate the comments on laser falsing.

Re-routing the rear laser cable away from the trunk release solenoid may stop the falsing but it also may be the proximity of the solenoid to the shifter itself too. Either way, it may be more work than it's worth.

As for the falsing on the highway. The ZR4's laser sensors are more sensitive to laser than a windshield mounted detector. You may be receiving alerts from vehicles with blind spot and lane change warnings. If the alerts happen very regularly then there may be a problem with a shifter.

Default (nearly) Eliminating laser falses caused by vehicle interference.

I run my Redline on a motorcycle, a CBR1000. First a 2007 (RIP, f'ing drunk driver) and now a 2012 HRC.

When installing my radar detector on the first bike my experience was false lasers as the machine hit 4600rpm, when I honked the horn, on hard accel in any gear, etc. etc.

An old mechanic's trick: I stretched the power wire out straight on the floor, stretched a length of uninsulated stranded copper wire the same length next to it, laid 4" wide strips of aluminum foil down, overlapping 4" where the strips meet. Then you unroll duct tape right next to the foil, same length, or a couple of shorter lengths if you're feeling weak and puny.


Set the wires (the RD wire and the bare copper wire) in the foil, wrap her up like a doobie, set the foil in the duct tape, repeat.
Voila, shielded wire.

The bared copper wire is to attach to the battery (-). I guess you could use a ground point, but why? Best ground is at battery. Making the bared copper wire the full length of the power wire serves me two purposes and may be optional for your setup. The first is that through the motorcycle I had small radius turns to make, 90's, double backs etc. and I was concerned about the foil breaking and losing contact with some section of wire over time. The solid copper guarantees ground no matter the breaks in the foil. The second purpose was it allowed me to ground the metal magnetic mount that the Redline sits on. This adjustable mount utilizes a body point which is not grounded.
Either way you'll need at least a little pigtail to connect to the battery (-).

This essentially eliminated any false laser positives from the machine. I can still get the horn to do it rarely if I sit there and bang on the horn while I'm accelerating on the highway.

I am in the process of installing a ZR4 system on the motorcycle and after I locate the system and custom-cut the wire lengths I plan on insulating all of the shifter wires in the same manner.

Funny thing...when I honk the horn in my 1996 Tacoma it will false laser! I just laughed and laughed the first time it happened, gotta be something with the horn harmonics and feedback in the power circuit.


Hope this helps.
