Yes, you would need one for the front and a separate one for the rear (if both sensors are bad). Because this is sending the message back to the computer that your lockers are engaged when you push the button on the dash, all the other indicators will still show correctly.

@@Quadratec great news! Thank you for the prompt response.

@@Quadratec I bought just one to keep for insurance. I'd think the odds of both failing at the same time would be pretty thin. If one fails and I use my harness, I'll buy another as insurance for the other axle.

My recollection is the actual sensor is still bad, but this intercepts the communication and always returns the 'correct/everything fine' response. So if your locker DOES actually go bad / not actuate you're going to have a real bad day.

Good question idk

Yes, if both sensors go bad, you would need a bypass harness for each one. If only one sensor fails, then you just need one harness for that axle.

Yes! Though, technically it doesn't fix the problem, but will allow you to use the locker with the faulty sensor.

This will work on the front as well as the rear. thanks!

@@Quadratec, спасибо Вам за ответ!

@@Quadratec hallo, sorry not clear for me, do you mean that the rear locker works for the rear and the fron blocker? Because i installed the rear z-locker but i still have the problem. Thank you

​@@zautomotive I recently started to get the light Service Axle Locker System light intermittently (2019 JLUR, 30kmi). It now always comes on when I brake lightly or even just let off the accelerator, and then it clears. I bought one sensor bypass harness (I would not expect that front and rear sensors have just failed at the same time). Put it in the rear locker, no change. Pulled the harness and put it in the front locker, no change. Removed the harness, no change. For fun, left a locker sensor disconnected completely, and light stayed on solid. Reconnected the sensor, went back to same intermittent light. Soooo.... electrical connection somewhere? it seems too repeatable to be a connection problem. But I am otherwise at a total loss on this and would love any other suggestions. I have a stealer appt scheduled but I really don't want to start seeing them swap out axles over this... if they even will any more. Thanks...

hi, did you fix the problem now? same situation, installed in the rear and still have the alarm in dash and ringing every 30 seconds.

I have had this happen twice to me. The 1st time my Jeep sat at the dealership for 3 months while they waited for a new axle assembly. It would have been nice to have this as an option to keep me back on the road while waiting for the dealership to get the parts for the repair. Or, if it happens on the trail, have it in the glovebox so that the locker can still be used to finish the trail. I agree that the $179 seems steep but I would have gladly paid that vs being without my Jeep for months.

Yes, this was made for owners that have had their locker sensor(s) fail and cannot, or choose not, to get the repair done by the dealer. An actual locker failure (not just a bad sensor) really boils down to a broken locker that will not engage or will not disengage, which you should be able to identify from the seat of your pants.

@@Quadratec great feedback. Thank you. You guys are always so responsive to your customers!

@@darrenroos6408 sounds like there is indeed a market for this! Thanks!

@@darrenroos6408 Wait until you are out of warranty and discover the cost of an entire axle assembly. You'll then view $179 from a different perspective.
