a way to trick the ECU or EPROMS?

[pgarland]

I know this is one of those asked and answered a million times type questions, but my situation is different, and I have tried EVERYTHING to get my car to go into programming mode for my two key fobs. Before you jump on me, let me explain that I went through every single step in that long thread about reprogramming key fobs (the huge merged one), I jumped pins 1 and 4 on my OBDII connector, within ten seconds I turned the key from OFF to ACC, my door locks would not cycle. I then took the car to the Mitsubishi dealership, and working with the Mitsubishi mechanic, we took out the back seat and interior panel (driver's side) and verified not only that the factory installed wireless receiver was there, but that it also was working as it was supposed to. The Mitsubishi mechanic spent 3 hours trying to program my key fobs the "right" way (with the scan tool), but could never get the door locks to cycle (to indicate that the ECU is in programming mode). I am at my wits end here, because after checking, rechecking, and verifying serial numbers on the Fobs, the factory receiver, and making sure that everything is as it is supposed to be on my 99 Eclipse GS, alas, I still cannot get my ECU to go into programming mode.

I have no CEL, and no faults showing on the OBDII scan tool. EVERYTHING else in the car works fine (including the power door locks), and I have gone through the troubleshooting charts from the e-manual that I downloaded from this website.

Any ECU or EPROMS experts here, is there ANYTHING I can do or check to resolve this issue? Is there any secret way of tricking the stock ECU to go into programming mode in order to get these Fobs programmed? Absolutely ANY advice is welcome, but if you are going to refer me to any threads on this site about programming key fobs, I can pretty much guarantee I have read them, printed them out, taken them to the car with me, and tried every suggestion multiple times, with absolutely no luck.

Thanks in advance to all who reply, I'd really just like to get these damned fobs working so I can put my backseat back together and move on to other projects!

Have you made sure the wires aren't loose in the OBD port?

Definitely have checked all the pins, and all the wires looked okay (visual inspection)...and just to be redundant, I even verified by connecting an OBDII scanner to the port again...the scanner wouldn't read correctly if one of the OBDII port pins were bad (right?).

I did mine by switching the keyless entry ecu behind that panel on the drives side rear, into programing mode right at the ecu itself, I cant remember but I'm thinking that there was a switch right on the box or in it or a jumper or something to put it into learn mode right there rather than at the diag port.

How about it, does anyone know if I am supposed to read 12 volts if I hook my multimeter up to ports one and four on the OBDII connector and turn the key to ACC? Sorry to bump the thread...and I promise Paul, I won't do it again...just need an answer to this simple question, as I think I can solve all my problems with just this little bit of knowledge (well, at least narrow down where the faulty wire is in the system)...

OK...I checked for voltage between ports 1 and 4 on the OBDII connector. It is reading a constant 7.65 (8), regardless of what position the key is in (OFF, ACC, ON), it is even reading 7.65 with the key out of the ignition.

Can ANYBODY tell me if this is correct?

I just bought my 99 GST Spyder last weekend and it came with two key fobs. I tried and tried to get them to program by using the 10 sec directions and it would never work.

This probably won't work for you since the Mitsubishi dealer couldn't program your remotes but this is what I did: I took a paperclip and connected it to 1 and 4--make sure that it is pushed up as far as possible. Then, I closed the car door, put the keys in the ignition and switched the ignition to ACC and back to off. The locks opened and closed, I pressed the lock button on the remote 3 times and the programming took.

Yeah, I have tried that...problem is my door locks have yet to cycle for me (no matter what I do). I swear I have tried everything at this point, I'm down to chasing wires, but have decidedly moved on to other projects for the time being. I'm sure in the end I'm going to find out it was all due to one little wire or pin being slightly out of place (or something equally stupid), but I have to say, I'm done letting this seemingly easy task whoop my butt for a while.

Thanks for the reply though.
