Does 99 maxima need reptogramed after replacing bcm
I think my bcm is bad. If i buy a used bcm from a 99 maxima can i just plug it in and car be fine or it have to be reprogrammed. Thanks for any help
|
Is there a way to reset my bcm. Does removing negitave battery cable for 15 minutes reset bcm
|
I replaced mine and didnt have to reprogram anything. I just unplugged the battery and took it out and plugged the new one in and plugged it back up and its been fine.
I have a spare that works if you need it. Just have to make sure the numbers on yours match and all. What year is your car? |
My car is a 99 what year is yours

My 99 maxima 3.0 auto
Bcm Part # 2ht 28491 4l 700 8z18 I found a lot of used bcm on ebay but couldnt find one that all 3 sets of numbers matched up. Closest 1 i found was from a 99 maxima with manual trans the bcm # 2ht 28491 41700.i thaught manual trans would be different than auto. I have no idea what trim level my maxima has |

Does mine have to come from an auto. Or will it work as long as it has the numbers are 2ht 28491.4l 700. Can a bcm also cause a random misfire

It has been said that the 99 coil packs are sh!!tty. That is probably the misfire problem. Any ehgine codes to report?
|
It has a 0300 engine code. I put new spark plugs in it and new coils. Sometimes it has a 1105 code. I cleaned map senspr and i can feel the map switch sylonoid clicking when key switch is turned on
|
Those are intake manifold codes. Check for manifold leaks. Only use NGK spark plugs.
|
Thanks for the info. Ngk is the plugs i used. Tomarrow i will check for manifold leaks. When warm idling in gear sometimes it will idle rough while driving it runs smooth. I even changed fuel filter thinking that would help. I ordered a bcm off ebay hoping it will fix my windows locks cruise control and rear defogger

Thanks ill check the rear window switches. I baught the car with windows and stuff not working. I fixed the rough idle issue. You was right it was a vacumm leak. I found a small vacum line unplugged from the manifold runs and idles good now. Next is to fix the windows. I love this forum lots of smart people with good info.

When you need parts like switches and handles and that crap, go to a junkyard where the parts are cheap. Also, If you need to see how something is hooked up, sometimes you can see how it is done looking at a junkyard car. Usually things are in normal shape after a wreck except for the smashed parts. A junkyard is a good go to place.

I replaced bcm today. Same thing i have no rear defogger no speed cruise windows and locks dont work. Dome lights dont work with doors key ring dont light up. I checked rear window switches to make sure they werent on wrong sides. I have no idea what to try.
|
You have checked the fuses already i assume?
|
Yes i checked all fuses with a testor there all good. I tried switching relays beside under dash fuse box.
|
I got key ring lite dome lights and elec. Door locks working still no elec. Windows. For some reason door locks automatically unlock them selves as soon as there locked. I cant figure out whitch relay goes to windows
|
I double checked fuses. Under dash fuse box
two fuses not getting power #5 marked tail lamp 7.5a #18 marked interuor illumination 7.5a What can cause both fuses to not have any power. My tail lights and dome lights are working. Thanks for any help you can give |

Thanks for any help you can give Maybe you have a faulty window switch? Snag one from a junk yard and test. Only time it would unlock soon as you lock it was if the key was in the ignition typically. This is interesting. I wish i could be of more help. |
Oh your right i just tock the key out and it stayed locked my mistake. I baught two master window switches and none work the windows. I can lower and raise window by hooking wires straight to window motor harness. When i push window button i can hear clicking
|
Solved. It was a bad switch wire to rhe power window relay. The red wire with grey stripe for switched hot into the power window relay wasnt getting juice. I hooked that wire to a fise link and to battery and windows cruise control and rear defogger is working good. I need to find a better place to hook the wire but everything works now. The relay is behind driverside kick panel. It has white/red wire yellow/red wire black wire red/ gray wire. Thanks for all the help
