how do i totally reset my computer. disconnecting the battery isn't working cause all my presets for my radio stay on. i am trying to get my airbag lights to go off. as some no i got new seats and the lights are on now and they were not before. please help thank you.

 

The radio has a built in battery that holds your settings. Resetting the PCM will not reset the radio presets.

 

will it reset my airbag lights to make them go off.

 

to reset your computer, you need to remove the neg, battery cable for a few minutes. when reconnecting if the lights dont go off, than you need dodge to wipe the pcm clean an reinstall the software, my truck was 90.00.

 

i got a dif year but when i reset mine i left it unlpugged for 24 hrs.
overnight is probally enough tho.
this cleared my cel should work for the airbag light.

 

I bought a USB OBDII scanner on eBay several years ago. I haven't tried it on my Dakota yet but I was able to reset the computer in my Contour (which came in use everytime I needed an e-check ). It was $60 then and I think they have gone down in price since then.

Are you the one with the new leather seats and having trouble with the airbag light? If so, I already told you in that post how to clear the ECU.

Disconnect the positive battery cable from the battery,
ground the cable end for 30 seconds,
reconnect,
turn key to ON position,
wait for fuel pump to stop pumping,
start truck.




This is the ONLY way to completely clear the ECU. Any other way does not discharge the capacitors in it. Dealers do it this way, atleast the Techs that know about it. They won't tell you though, I will and did, as I am no longer a Tech.

 

This might sound dump but how do you ground the positive when the cable isnt long enough?

 

It should be long enough to touch the fender... hell I have heard ppl pulling both postive and negative and touching them together... it all works the same...
