Welcome, I'm Chris (aka Moose).

  • Although I work here everyday, please understand it is not all day and rarely morning time.
  • To get the most from me and the best experience, please give me the best details you can.
  • The website will offer you a phone call option for more $$. Some I do fulfill and some I do not.
  • Thanks, let's get started.

Do you have the ability to get it scanned to see which codes are stored?

no code stored
Jeep Mechanic: Chris (aka-Moose), Technician replied 11 months ago

Using your scan tool will it allow you to monitor the ABS wheel speed sensors and the transfer case encoder motor position?

Jeep Mechanic: Chris (aka-Moose), Technician replied 11 months ago

What model scan tool was used, not all can access codes outside of engine concerns?

hi
Customer reply replied 11 months ago
Autel MaxiScan MS509 OBD 2 /EOBD Scanner
Jeep Mechanic: Chris (aka-Moose), Technician replied 11 months ago

That scan tool only has access to engine codes and will not work to diagnose this concern on this vehicle.

A better tool will be needed.

One of the more common concerns that causes this light is a worn clutch in the transfer case from mismatched tire circumferences.

Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris

pleas have you got the part number of worn clutch in the transfer case?
Jeep Mechanic: Chris (aka-Moose), Technician replied 11 months ago

This part is not serviced separately, a replacement transfer case is needed if this is the cause of the unknown code stored.

Thanks Chris
