how do you test and OTIS/EVIC out of car?

I've read somewhere on here that you can test an OTIS/EVIC with a 9-volt battery. but all I did was find mention that is was possible, not the proceedure...

I don't have my harness yet and want to test my EVIC... four wires coming from EVIC:

Purple with Yellow stripe
Black with Green stripe
solid Pink
Blue with White stripe

thanks
Dave

hmmm, the only thing I can think with the 9 volt battery would be testing the lights...

when i bought my evic, I also got a full upper harness from TFC. I just plugged the harness into the junction block and hooked up the evic and it worked outside the car for testing. you could take wires and affix(jerry-rig) them somehow to the pins at the junction block and somehow the 4 pins at the evic and test it

You can use a 9 volt battery to get the otis to turn on, but not test the functions which would come from the junction block. When I got mine from spyderman here, I took a 9v and connected the black wire to the negative and the pink and also the purple wires to the positive and the screen came on. The compass function will work out of the car and also the counter but the other functions that come from the bcm obviously don't display correctly. Double check on what wire is for what because my memory is a little foggy because its been over a year since I looked at this stuff. I know the black is the ground for sure and the pink is +12 from the battery since it is shared with the map lights. The blue I believe is the info wire from the bcm and that leaves the purple as the +v from an ignition on source.

what you can do is, plug the harness end into the Otis/evic, and plug her into the Distribution block inlet(where it would go into for the otis/evic), and then turn on your car, reset everything on the display, and there you go, now as far as compass/tpms testing and all of that, thats where the calibration comes into play, keep in mind taht the regions differ for compass calibration ect..., meaning you will have to recalibrate the system, as stated in the owners manual!, ;)

Yes, that is the easiest way if you have the wiring harness handy. Otherwise if you are on a quest through the junkyard to snag one, take along a 9 volt battery and you can test it on the spot. Save yourself the trouble of buying one only to find out later its not working. Handy to know since a battery fits right in your pocket.

true!, , also when t aking a chance at the yard, alottt of the otis's/Evic's have water int hem, and that can be a nitemare!, especially plugging it in to you bcm,a nd frying it, ect..., You dont want to happen now!, Do you??, helll no!, so be very careful!, I think the 9-Volt battery, if infact works, is the best/SAFEST method, so be it!

the pink wire I believe is for memory fuction for the run time counter. The pink wire is connected in the car to a + battery voltage, meaning it is constanly on. the purple wire is the actual one that will turn on the display to the OTIS.

Yellow wire? The only yellow wire I know of is the one for the map/dome lights and that's purpose is for the dimming feature the bcm does with the dome lights.

the blue/white is the bus wire and the purple/yellow is the + ign.

Darn, my memory seems better than I give myself credit for.

yeah, but there "IS" a bus wire (maybe the violet w/ the yellow stripe?), I think it controls the average miles /gallon, ect....., distance.....

I know there is a bus wire, luie, I'm pretty sure its the blue with white stripe though.

edit. I'm sorry luie, you are correct. the purple with yellow stripe is the pcm bus wire. The white with blue stripe is +ign. I had to go back and look this up. I want to make sure I put the correct info out there before somebody sticks a 9v battery on the wrong wire and fries it. I know it works when connected to the right wires because I had done it.
