4x4 low range
Hows it going fellas. Happy Holidays. Ive got a question. My low range wont engage. I have a bw1356 elec shift. Ive been doing a lot of research on here and i think its my powertrain control module. about a month ago i was search the threads and saw one that was talking about a button on the pcm that you could push to test it. i think someone said that you could push it...if it blinks the your shift motor is bad but if it stays solid then the actual pcm itself was bad, or visa versa. Does anyone know what the light signals mean??? Any help would be much appreciated!
Thanks
Thanks

Me to, only electronic TC I had was on a bronco II and never had any trouble with it.
I guess the first thing I'd do is pull the shift motor clean it and test it. If it was found to work I'd put it back on and work forward from there.

Sorry Cody I didn't see this post before.
You're a bit confused. You don't want to be looking for your PCM, that's something completely different. You're looking for the 4wd Control Module. It's located under the passenger kick panel.
Upon remove you'll see it, little black box with a red light and white button. Remove the 5 pin and the 8 pin connectors on the bottom, turn your key to ON, and push the white button. If it blinks repeatedly (about 1 blink per second), then it's good. If it has lights up solid for several seconds then it's shot. Report back and let us know what you find out brother.
