passive lock with valet 712t?

I installed a Valet 712T Keyless entry on my 1994 Chev S10 pickup.  It works great but lacks one feature that I sort of thought it would have... passive locking.  The install manual says it can do this with the optional Failsafe starter kill relay installed but it does not show how to connect or exactly what parts are needed.  I can't find this part sold separately anywhere.  Can anyone help?

I see that Viper (also DEI) has a 211 HV keyless entry that has passive locking.  Would my existing 712 harness plug up to the 211hv module or are the wires/connectors different?

Thanks,

Ray

I have had Clifford passive arming alarms since 1984 so I am used to the routine.  But I have managed to leave the keys inside twice.  Once was when I did it intentionally when the remote was separated from the keys.  But then the battery died and couldn't make even one more pulse. :-/  But the last instance was a loooonng time ago.

I wish I could see the wiring diagram for the Viper 211V to see if the connector is set up the same as the Valet 712T. I bet it is the standard DEI connector but maybe the wires are in different positions.  If so, they could be rearranged.  But I can't find the insatll manual for the 211HV anywhere online.  I wish soimeone would post it.

OK, from a 1990 DEI 712T Manual....  two jumpers  Yellow (ignition lock) Red (passive/active)  (cut=active mode)

I dont know if this is yours though, you say theres a +/- jumper?   Whats the date code on the module?, that'll help

Actually the jumper is to select between + and - parking light flash output, not dome as I said above. 

I don't have the module number.  I'd have to disassemble the dash to find it.  But it is a recent purchase so should be a recent iteration.

I recall the one jumper as stated above.  No dip switches mentioned in the installation manual that I recall, but  can't put my hands on the manual now to double check. I may have lost it. :-/

Interesting that the Owners Guide (not install manual) states that "If power locks are connected the system can be programmed to automatically lock the doors in 30 seconds".  But on the page that actually discusses programming options that is not listed.

Typically DEI systems turn these features on and off by a specified number of flicks of the valet switch.  I think the 712T probably can do it but for some reason just isn't listed in the manual.   If we just knew how many flicks (in this case presses) to do....

It gets wierder....  I found my install manual and under the section about transmitter learning it walks you through programming for Passive Arming!  But..... it looks like it is basically a tutorial on programming features in general with the right combination of valet key presses to select the feature to be programmed, and they happen to use Passive Arming as the example of feature 1 (one press of te valet button).  But in the table of programmable features on the very next page feature 1 is actually ignition controlled locking (doors lock after 3 seconds after start) NOT Passive Arming.  And Passive Arming is NOT one of the 8 features listed there!

My guess is that they just cut and pasted the how-to-program from a system that has passive arming as feature 1, unlike the Valet 712T, which I am beginning to believe doesn't have it at all.  I am wized.

To shed some light on this,  I reviewed the manual and found no passive arming at all.  This is the manual that I have seen on the directechs website

I was talking about the Install Manual above.  That is not available on the DEI websie.  But the Owners Guide on the DEI website (and that also came with my system) does indeed mention passive arming in at least 2 places.

From page 8:

Well, next time I take the dash apart I'll check the stampings.  Not on my near term to-do list.  But it is a current model Valet 712T, purchased online 2 weeks ago from A1 Auto Electric.

Until proven otherwise I believe that we have some bogus verbage in the installation manual that looks like it was cut-and-pasted together from a generic DEI alarm manual template. I also believe that this particular model has no passive lock capablities as evidenced by the lack of such a feature in the programmable feature table which may be the only part of the manual that is specific to and accurate for the 712T.  I HAVE tested programming of the features listed there and they do work and in fact track with what the unit does.  Too bad passive locking isn't one of them.  :-(

I sent DEI an e-mail query.  I wonder if they'll answer being that I am not an "authorized dealer".  :-/

I just looked at an installation manual online (copywrited 2005) and it uses the same wording as to what was already posted. I would have to say that passive arming is not an option.

Amen!  this box does NOT have passive locking.

I'm told DEI had to spend too many $$ repaying owners locked out of cars.
