2003 Acura MDX door locks

I put an Autostart 2400 (the new design 2-way remote starter unit) in a 2003 Acura MDX. The locks are neg trigger and i connected them in the passenger kick panel.  The lock wire was BLACK/ orange and the unlock was blue/orange in a connector just above the fuse panel. Everything worked fine at first and the customer returned today because the keyless entry didnt work. The factory keyless entry still worked but the starter keyless entry and the passenger door lock switch didnt work. You couldnt even lock or unlock the doors by probing the wires with a test light. After replacing the brain, everything seemed to work fine again, but after starting the vehicle and waiting about 3 or 4 minutes, the door lock problem happened again. We changed the brain again assuming it was ANOTHER bad brain. Door locks worked fine and yet again, after about 5 minutes of the car running, the door locks stopped working. Ive never seen this before, i dont understand why it works fine until after the vehicle has started and idled for a few minutes. I figured maybe it was child safety locks or something but its not. The passenger door lock switch also stops functioning, but works once you unplug the harness with door locks from the brain. anybody seen this before?? any ideas would be appreciated....thanks

You got the wrong wires buddy. You need to get inside the drivers door for them.

LOCK and arm is blue/white

UNLOCK and disarm is blue

any time you replace a module and the same problem happens to the 2nd one - thats a sure sign its not the equiptment. When I have to do troubleshooting I always remember that the product is defective out of the box maybe .5% of the time. The rest is something wrong that I am doing or something that is missing. Ask any EXPERIENCED installer on this forum - they'll tell you its usually NOT the product!

Good luck

Chances are it's the AUtostart CPU that causing the problems

im almost positive I did this car before.  I think the lock wires are at the passenger side fuse box.  I think the colors are Lock - BLACK/ orange, unlock - blue/orange..  I may be wrong, but Im almost positive.

That is unless it's a magicar.  Then it's defective out of the box about 99.5% of the time.  So far out of 20 of these things brought to me not one has worked properly out of the box.  That's even testing the units on the bench before they're even close to being installed.
