2003 Mitsubishi Montero Question: CENTER DIFFERENTIAL LOCK DETECTION switch

 

Question

I have 20th anniv montero, had some engine repairs done last March ever since the day I brought home and first drove on highway ---I drive 2H highway speed 60mph plus for 15-20min. the 4wd display front and rear wheel lights go out and center differential lock light blinks continuously. Only way to fix is pull over restart vehicle. The ride doesnt seem to change, am I doing damage to vehicle 4wd transm system by ignoring? Is it an electrical problem since my engine was removed and replaced?? Is this a common problem? I have read that there's a switch is it necessary to fix? In owners man. this light flashing means a "problem is detected in the transfer system". Does anyone have a suggestion? I did some research in a service manual trying to find "L CENTER DIFFERENTIAL LOCK DETECTION SWITCH and found its a part of TRANSMISSION WIRING HARNESS CONNECTOR DISCONNECTION.
What is this ? Is this labor intensive to replace is it a necessity to transmission/4w operation ? Is there a tool that only Mitsu mechanic can use to diagnose why this light blinks and appears to kick me out of "2H" car seems to be running the same. Help this vehicle has already cost me way too much $$/heartburn!

    hey man i have the same vehicle 2003 montero 20th anniversary edition. im sad to hear your having the same problem i had. the problem is actually your gear selector switches. nothing wrong with the car just the transfer case switches are most likely intermittent. i actually went through a difficult process because one error was masking another error. so when you do take your vehicle to the shop make sure you have time. i mean alot like a week. cause the part has to be ordered from japan it cost me about $850 at the dealership for the service. but do make sure they test drive the vehicle on the freeway to make sure code doesnt come back on cause it normally doesnt come on till youve driven 65mph+ for a while. so make sure they do that and check for a code that could possibly be masked by another. let me know if you figure it out and congrats on your fine piece of machinery. check me out at http://www.cardomain.com/ride/3372954

    I had the same problem with my 2003 XLS. I took it to a local shop that had an ex-mitsu mechanic working for them who say he used to see it all the time and the switch contacts needed to be cleaned. He took all the switches out, cleaned the contacts and sealed them up for $60. That was three years ago and the problem has never returned.
