'95 Sentra GXE Keyless Entry

draasch,

well, I "attempted" to install the keyless entry system into my Sentra this weekend.

Wiring seemed to go fine.  I tested the wires with a DMM and indeed found the lock/unlock wires and they indeed grounded out upon activation. (negative pulse)  Then I found a Constant +12V in the same bundle and tied the fused red wire to that.  Then the instructions said to tie both the Polarity wire(purple) and the Chassis Ground wire(black) to ground.  When I touched the Black wire to chassis ground, the "door tone" went off(constant).  You know.....the one that sounds intermittently when you open the door either with your keys in the ignition or the lights on. I attached the purple to ground and nothing changed. Same constant tone.

There is a red button on the receiver module that you are supposed to press to manually learn a remote.  It is supposed to "lock" the doors to let you know it is working.  When I pressed it, nothing happened.

Has anyone ever heard of this? I looked for shorts on the board, but didnt see any, although it did look like a transistor had been replaced..

It is an IC Dynamics system.

thx for the help

anyone out there help me out???

I tapped the wires under the steering wheel instead of the kick panel....Right where they go into the relay....That should not have presented a problem either, right??

thx

Take the RED fused wire and go straight to the ignition switch constant wire ( WHITE/ RED ). The little RED wire that you tapped into will not have enough power to operate a keyless entry system and will most likely cause you some problems. Next is to ground the BLACK wire to chassis ground , make sure it is a clean, paint and dirt free spot.

If the wiring seems to be good and you metered all the connections and the problem persists, chances are it's the CPU of the KE unit that is the fault.

Thx for the help, but I did not tap into a little red wire with the Fused Keyless Wire.

What AWG is the Constant +12 I am looking for??  ~~18 AWG'ish??

Do you think not having a big enough Constant +12V would cause the car tone to go off when I hooked up the black wire to ground??

thx for the help
