No Parking Lights Flashing Indication:
QUESTION: "Hello I bought a used truck about four years ago it's a 04 f150 fx4 it had an ultrastart brand u1250 model remote start/ keyless entry system, it worked perfectly until about three weeks ago. When I go to unlock/ lock the doors the parking lights no longer flash if I'm in the truck and try I can hear the clicking which it does when the lights were working, also when I use the remote start the dash lights and parking lights no longer work again if I'm in the truck and remote start I hear the clicking it would normally do. I checked the inline fuses that I found 2 30 amp and 1 10amp and they all were fine. I checked for bad connections and none found, I looked at the module itself (the brain) no damage to the outside opened it up, and no burns or damage to the circuit board. I've got the user manual but it has no advice on what the problem is, the only thing I found online was that it could be a bad output to the lights which I have no idea is or how to fix it. Any help would be great thank you". From Semper Fi
ANSWER: OK, First, because you can hear "clicking" coming from the module when you use the remote means, "maybe" that one of those clicking sounds is coming from the systems' parking lights relay, meaning it may not be a bad output...the first thing you have to do is to get an automotive test light...nothing fancy, because your only testing for a +positive parking light output...first find where they connected to the vehicles parking lights...which will be a Solid BROWN wire in the vehicle and they either connected the systems' parking light output wire to the vehicles' Solid BROWN parking light wire right behind the vehicles' headlights switch OR at the trucks' trailer connector harness near the OBDII diagnostic connector (some even connect to it in a harness that runs towards the rear of the vehicle behind the drivers' side left kick panel)...then, connecting your test light to a CHASSIS GROUND, probe the vehicles' Solid BROWN parking lights wire...while the probe is connected, press lock and/or unlock on one of your remotes'...see if it lights the test light when you use the remote (probably, it won't) so, now move the probe over to the systems' parking lights output wire that's connected to the vehicles' Solid BROWN parking lights wire...and test it the same way...if the test light lights when you use the remote, all you have is a bad connection...if it doesn't, you have a bad parking lights output from the system...because you already checked the fuses.
