I replaced the tumber and key in my 2002 s10 le 4x4 with one from a 2002 s10 2wd,im 4x4 has a 4.3L and automatic,while the 2wd is a 2.2L and a standard,now it wont start


if you replaced the ignition cylinder housing as well the passlock system will have to be relearned. Hook some sort of battery charger or stabilizer. attempt to start the vehicle and just release the key to the running position....check security/theft light on or flashing. after about 10 minutes the security/theft light should go off, turn key off but dont remove for 5 seconds, then attempt to start again. Do this 3 times for a total of roughly 30 minutes and it should start.

Engine light is on, flashes when driving above 100 Km


stop by local parts store (Autozone,Advance, etc) and have them do a free fault code test. They can print out a list of faults and clear the codes

Why is the 4wd light flashing?


i had the same issue with the 4x4 light flashing and the anti-lock brake light on while in 2wd. what seemed to fix the problem was to have the sensors for them cleaned periodically. i had a shop do it so im not really sure where they r located.

4wd light keeps flashing on 2003 mitsubishi challenger


Hi Adstew,
the front diff has a sensor telling the control unit it when it is engaged (or not). It probably is, and it won't disengage. or the sensor is stuck. The selector lever tells the control unit you want 2WD but the sensor thinks the front axle is engaged. So it flashes.
When shifting to 2WD, normally the front axle will come free after a load change or a bit of turning the steering from side to side, but it sometimes happens that it gets stuck. You can find out:
lift the car free off ground, then select drive forward in 2WD. If the front wheels do not turn, then the sensor may be faulty or stuck. if the front wheels turn in 2WD mode, the diff is stuck and the sensor tells you so. Same or similar problem can happen with the center diff, by the way, on pajero/montero, etc.
regards
Winfried, the perfessa

Intermittent Flashing 4x4 Light


This was a weakness of the Montero Sport models. If you google Montero Sport 4WD light flashing you will find lots of information. The best troubleshooting article I have found is here: http://4wd.blogeasy.com/article.view.run?articleID=318776 This article is about the Pajero, but the Montero Sport uses the same platform so this article applies.

The Montero Sport uses several switches and vacuum modules to put the system in and out of 4WD. If any of these malfunction, the light may flash continuously, flash intermittently, fail to come on, and it can trigger the anti-lock brake light to come on. In brief, if the 4WD shift lever is engaged, but the transfer case doesn't engage, the sensors show a mismatch and will cause the light to act funny including triggering the vehicle's anti-lock break light. These SUV's need to be shifted into 4WD regularly to keep the switches and mechanisms working correctly.

Try this before you even think about a visit to the $$$$$ Mitsubishi Dealer:
Shift the 4WD lever between 4WD High, Low and 2WD at least 100 times. Often, this will free the mechanisms and resolve the problem. It worked for me after three years of trying everything else including the dealer replacing switches, etc. If this does fix it for you, just be sure to shift the vehicle in and out of 4WD several times at least one a week and this will keep the mechanisms lubricated and functioning correctly. If that doesn't work, try the above link (article). Good luck!
