Prius (2004-09) :: Door Open (Ajar) Warning Light Staying On

My 08 Prius developed a hiccup yesterday. While driving down the interstate there was an occasional red flash from the dash. It would come and go so fast that by the time I could actually process it and focus it was gone. I had to stop by the dentist office as I was ready to walk out the door I heard a car in the parking lot with the horn/alarm sounding. I mentioned to the folks in the waiting room that someone alarm was going off. A lady replied that green Prius with the bike rack!

Sure enough it was mine! I was unable to find any causal factor. I left there and at my next stop, the horn/alarm started sounding just as I walked through the entrance door to Home Depot back to the parking lot. This time the Door Ajar/Open light on the dash was lit. I opened and closed all the doors and hatch. The Door Ajar light was still on I then manually manipulated all the door switches and opened/closed/slammed the hatch several times. No Joy I drove home.

About the only thing I was able to find was that it was probably the hatch, the switch is sealed within the locking/latch mechanism and that I could simply just unplug it. So I began troubleshooting.

After removing the rear hatch/floor, plastic bin, etc. I removed the plastic cover from around the latch (above the bumper not on the hatch lid), then removed the longer plastic cover that runs along the same area and provides the cover for the area between the rubber gasket and the inside of the hatch/floor area. Now I was able to see the latch mechanism and associated wiring (looking down toward the spare tire well). I also had the hatch light turned on (left side) which was easier to see than the Door/Ajar light on the dash.

I manually tripped the latch and the light flickered. I pressed down on the latch (hoping to put more pressure on the internal switch)…the light continued to flicker. Using a 10mm socket, I removed the latch, wiring retainers and disconnected the plug. The electrical plug, located about 8†to the left of the latch has 4 wires. The two on the bottom power the electrically operated latch and the two on top go to the Door Ajar switch (the one that is inside the latch assembly).

I noticed a little bit of corrosion and discoloration on one of the male pins (the plug that is connected to the latch end of the wiring). The female plug (connected to the car end of the wiring) also had some discoloration.

I plugged them back together and found that as I moved the wires/plug the light would flicker and change sometimes turning off. I unplugged it and connected my ohm meter (using small jumper wires with clips) to the two top (male) pins on the switch end of the plug. The switch tested fine. I even tested it with my homemade battery powered continuity light (wanting to test the switch under a load). I also wiggled the wires going into the plug itself, Perfect, no problems here! So, I determined the problem was truly with the plug itself. I also jumped the two female connectors with a short piece of wire (simulating the switch) and the light would come on (as it should have). OK, plug problem confirmed!

I cleaned the pins (both male and female), applied some dielectric compound and plugged it up. The light remained off for a few seconds then started flickering again! I could even hear a slight hissing sound coming from the plug (never a good sign). I tried tweaking the male pins (bending them slightly trying for a better connection) No Joy.

I clipped the wires (only the top two) from each end of the plug (red & white/black stripe wires coming from the latch).

Ford 6.7L Power Stroke Diesel :: With Door Open Door Ajar Message Goes Away?

Having issues with the door switches. My driver door, when opened, will cause a quick "door ajar" message then go back to as if I closed the door. Only once have I closed the door to have the dome light stay on. Doesn't do it all the time but is more frequent with the cold weather setting in. I got the service truck next week so its a good time to bring it in for warranty work.....

Ford - Explorer :: 2003 - Door Ajar Message On Dash With A Beeping Sound When Driving

I just bought a 2003 Eddie Bauer Explorer. I keep getting a door ajar message on my dash with a beeping sound when driving. I've opened and shut all the doors to make sure they are properly closed but it does not fix the problem. The interior light will also turn off and on randomly whether the car is on or not. What makes it more annoying is that when I lock the doors the alarm sounds, thus forcing me to leave the car unlocked at all times. I could not find any door buttons against the door frame so can't figure out why it thinks a door is open. How I can fix this or if a code reader will tell me which door is the problem?

Prius (Gen 2) :: Parking And Warning Lights Become On With Transmission Message

This has happened to me twice (just today and about a month ago). The first time I was just sitting in the car, turned it off. It was hot outside so I just hit the power button without my foot on the break to start up the air conditioner. After a few minutes, a message pops up on the screen saying something about the transmission couldn't put the car in park and to park it on a level surface. I was on a level surface. I tried to start the car and it wouldn't start. After several tries, including inserting the key fob in the slot it finally started.

Today, I had almost the same scenario, only I was just returning to the car. Four warning lights came on, the parking break light was on (even those it wasn't engaged), and again the transmission message came up, saying I should move the car to a flat surface. After fiddling around, I got the car started again and immediately went to the Toyota dealership. I was just there yesterday getting an oil change and a once over safely check before I head back north which is a total of 24 hours of driving over several days.

Ford F-150 (2009-2014) :: 2011 - Door Ajar Warning Won't Go Away

My f150 out of the blue says "driver door ajar" when I was on the highway today. The interior lights also came on. I opened the door several times, even slammed it. But still the warning will not go away. When I shut it off and get out, the chime and lights stay on until the accessories time out after 15 minutes. What do I do to fix this? Will be hard to drive at night with the interior lights on.

Prius (2004-09) :: Intermittent Warning Message - The Transmission Lock Mechanism Is Abnormal

My 2005 Prius has about 140,000 miles. I had been getting the intermittent warning message, "Caution: The transmission lock mechanism is abnormal" although the vehicle has been able to start and drive just fine. I replaced the 12v battery, which was suggested in several other threads. However, the warning keeps reappearing. Possibly related, my gear shift knob is "sticky". I'm able to get it into each gear (and the transmission remains in the gear selected), but the knob does not move smoothly like it used to.

Ford 6.0L Power Stroke Diesel :: Door Ajar Warning Under Acceleration

I don't think it is the switch. About 3 months ago towing a heavy load I smoked my Trans during that time when the transmission got over 220 the dome lights would flash and the door ajar warning would flash. I just thought it was a high temp warning. Now tranny is fixed I was towing another heavy load and it started doing it again but all temps are good. I Unhitched load and now it does it most of the time when I accelerate. It seems to do it only under load on the engine. Called ford and they said it's not a warning and they think it's a electrical short. But it only does it if I accelerate.

Ford Excursion :: 2002 V10 - Constant Door Ajar Warning / No Dome Light On

Bought a '02 V10 gas 4wd Ex a week ago pretty cheap, and looking to fix a multitude of little issues.

I have been reading about the door ajar warning light issue, and mine alike has door ajar light always on. However, my dome/interior lights do not react to the opening of any doors/rear door hatch.

It's not out of the question that the last owner might have disconnected what he needed to to avoid fixing the problem and still use the truck. Where to start given I can't troubleshoot down to one particular door ajar sensor?

Ford Super Duty (1999-2016) :: 2013 - Driver Door Ajar Warning?

I have a 2013 F350 CC 6.7L Lariat. The last two days I have been getting the Driver's Door Ajar warning coming on every time I get in the truck. Sometimes it will go off by itself, other times it wont. If I lowly push the door shut, just before the door latches completely closed the light will go off. But as soon as the door closes completely the light comes back on.

I tried squirting WD40 in the lock mechanism as recommended in some older posts for other models. No worky! I searched Fordparts.com, but cannot find a listing for the door ajar switch. Where to find the switch for this warning light?

Prius C Fuel :: Cruising Range Drops When Gas Gauge Get Down To One Rectangle

Ok, had the prius c four for a few months now. What is up with the gas gauge? When I get down to one rectangle my cruising range drops to like 9 miles. I got gas and put in 8 gallons, which means I had 1.5 gallons still. Why is it showing such low cruising range mileage? Looked through the manuals by couldn't find anything useful. Also, is there a way to see exactly how much gas you do have? The rectangles seem a bit arbitrary to me when it comes to representing an actual amount of gas?

Golf IV / Jetta IV :: Door Ajar Light Stayed On - Can't Figure Which Door Open?

So yesterday I installed a Kenwood Double Din with a back up camera....that being said I was in and around the car all day, door panels, trim panels, rear bumper etc etc all removed. After completing the install the "Door Ajar" light stayed on, on the dash. No interior lights remained on to show a doors open, and the trunk light goes out when the doors closed. The drivers side door module is no good, and its been no good for a few months now. It doesn't show when the doors open, so i doubt that is the problem. What it could be? Any way to figure out which door is the one that's staying open?
