How do I reset the Body Control Module in my 01 Pathfinder?

[Pierspeterson]

The good news is that I was told what happened when I removed the ELEC B fuse, but the bad news is that I erased the memory for my key chip...I was also told the only way to reset it is to take it to a dealership, many thousands of dollars away. Is there any reader or otherwise I could purchase to reset it myself?

Oh crap I high-centered myself the other week down by the river -- required the rental of a Bobcat to free it. I know how you feel. . nothing worse than having to abandon your vehicle.

We'll help you get it back -- after all, without a Pathfinder / QX4, you'd have no need for us. So uhh. . in the interest of member retention....

Give me a moment -- I'm going to ask all the moderators and see what we can find.

Short answer is yes, he has to go to the dealer. However, what fuse did he remove that lost the key programming? I was under the impression that the only time a keycode can be lost is if the ECU is changed. I could be totally wrong on that one though.

Is this an 02+ vehicle? Have him try to clear the codes first. You can clear the codes with a key sequence:

key on for 3 secondspress the gas pedal 5 times (in less than 5 seconds)wait 7 secondspress the gas pedal and hold for 10 seconds until the MIL starts to flash

if it flashes a code like a 16XX, that is an imobolization code. This will keep the car from starting if it has this code. To reset the code, (while in diagnostic mode with the MIL still blinking)...

press and hold the gas for 10 seconds until the MIL blinks a 0000 code which is clear. Then try to restart the car.

If he needs more details on checking codes, let me know. I've become an expert at it since I own a spec V.

You may want to give this a try. . if it's just throwing a code, maybe this will do it?

Thanks for the sequence, I will get a code reader and give it a try...Managed to tow it back to my garage, which is a good start, and hopefully this reset will work. Thanks!

So did ya get it reset? Dealing with 1610 and 1612 right now and have no idea why the key codes are lost. Hoping its just needing to be reprogrammed not replaced.
