Jeep TJ 318, 360, 5.2, 5.9 swap PCM W/VTSS bypass!

This is for those who have swapped in a 318 or 360 from a ZJ with VTSS enabled. If you can only get your swap to run for only two seconds, this is the likely cause.

First, remove the BCM from the drivers side, under the dash. Should only require a Phillips as far as I remember. Make sure to leave a few inches of wire on all three connectors.

The BCM consists of connectors C240, C241, and C383. From C383, you will ground the black and orange wire BK/OR (ground) and the purple and yellow wire VT/YL (VTSS SENSE). From C240 and C241 you will ground the black and orange BK/OR wire and the black BK wire. The purple VT wire in C240 (the one with the thick black ground wire) goes to a fused 20A source. I made my own, but you can use the cigarette lighter wire if you are stuck. That leaves the purple VT and the white and black WT/BK wires in C241. Those are your CCD + and - respectively and will splice into the same color wires coming from the gray PCM plug. That's it! You have bypassed the VTSS!

That's good stuff right there for the ones that need it! ^^ Good thing I didn't have it on mine.

You should also figure out how to bypass the LDP solenoid circuit, now I could use that.

I hooked up the BCM in my TJ as I described, turned key on, shorted the ccd, turned key off while shorting CCD and VTSS is no longer on the PCM! I no longer need the BCM wired in. Disconnected battery for 5 minutes and still starts right up!

Hope this is not a dumb question but is VTSS the same as the SKIM option or are they a different animal? I am hoping to put a 5.9 in mine this summer and from what I hear the anti theft stuff can cause a lot of problems. Dave

Very nice.

The FSM states the VTSS will activate after 20 starts. At least from the factory. Hope yours stays off.

Nope, SKIM is a different animal. VTSS is the alarm system and SKIM is the chipped key. Luckily, SKIM was not an option until later (1998), so it is easily avoided.

VTSS will only enable after 20 starts if you have your PCM connected to a VTSS enabled BCM.
