Prius (Gen 1) :: Door Ajar Warning Light Stay On All The Time - 12v Battery Drain
Jun 7, 2016
I have a Prius 2003 with 122k. My inverter water pump making noise it running but i do not see any coolant movement. Does this mean it a bad pump and need to be replace?
My door ajar warning light stay on all the time. I have check door sensors and the trunk lid sensor they all seem to be function. Where the wiring for the door ajar end up to the ECU maybe i can just short or by pass it? This maybe the cause of my 12V battery keep getting drain

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).

The Issue: Dash display reads "Passenger Door Ajar", interior lights stay on, drains battery
Current Fixes I've completed
Sprayed electrical cleaner in all 4 door latch assemblies (didn't work)
Relubricated all 4 door latch assemblies with food grade lithium grease (didn't work)
Replaced passenger door full latch assembly (didn't work)
What is my next step? I have noticed that if I wedge the door lock button on the driver's side door into the lock position, the door ajar message turns off and stays off? I was thinking wiring or relay issues?

I left the trunk of my 2007 Prius open long enough for the light to drain the battery. Once I jumped it, I was able to drive the 100 miles home, even though the red triangle warning light was on. Now when I turn the car on, there's a light I've never seen before, as seen in the attached image.

Door ajar light is on all the time. How do I check which of the eight switches are bad. I've tried the wd spray trick before and it worked but now it won't respond to that treatment and is on all the time. Overhead light goes out after a few minutes of driving.

My door ajar warning light stays on and at the same time the warning bell/noise keeps going off. Is there something that I can disconnect to make the noise stop?

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?

Yesterday morning my door was ajar, latched but loose, when I started up. I got a yellow warning triangle, a beep (I think) and message in a rectangle saying to put transmission in Park. My wife claims she saw a little car with open door symbol too, somewhere in the light show, guess I missed it.

Here are some signs of the problem.
*Key fob does not work - battery is good.
*Interior overhead light works only on manual.
*Driver's auto door lock (with driver door open) will lock all four doors but the driver's door will automatically open back. To secure the truck I manually lock the driver's door.
*I replaced the driver's door 'ajar switch' with no results. The old switch was good after testing - normally closed until the ball is depressed then it goes to open.
*No codes.
*I just checked all the mini-fuses with a VOM and they are good.
*Could one of the relays be part of the problem?
I am curious if there is a scanner that can identify the bad door ajar switch if any?
From what I have read so far it appears the VSM (Vehicle Security Module) may be bad as a many of these 2002's complain of this problem and the VSM generally solves the issues. Are there folks other than the dealerships that can program the module if I purchase a new one and remove the old OEM one? Other than the inconvenience the truck runs fine other wise.

I have a 97 Aerostar. The door ajar light stays on, and something is pulling the battery down it's a slow pull, that takes a week to kill the battery. I have found the power leak is on Fuse #8 the door ajar fuse. I have replaced the sliding door closed button switch and the passenger door switch.

Having issues with the rear tailgate door unlocking. Seems like mine on occasion is only making a noise but not unlocking completely and showing the door ajar light with the beep. When it happens, its a pain to get it to stop and close completely, or even open. I have to push hard on the door to get it to stop.

One day, I drove my Prius with my key fob in pocket. Parked the car. Turned off the power. Opened the driver side door to get off. Heard the continuous beep of "key fob in the slot" warning. I had never heard of it so I did not what it was. Tried closing / opening the door several times. The warning kept coming when I opened it. Tried getting off the car, pushed the lock button. It locked with lock beep normally.
After a few hours, I found the battery was dead. Had it jump started and the problem had not come back for a few weeks.

Will it drain the battery to leave the rear hatch open for extended time? i.e. for tailgating or camping (2008 Prius)

I have a 2007 Sonata. The parking lights won't switch off without a turning the lights on and off for some time. Repeated attempts can turn them off, but you have to check the car in a hour to see if they have come back on. The dealer stated this was a known defect of the fuse box assy, but there is no recall. 800.00 repair according to the dealer.Without an alternative, I am considering ordering the assy and changing myself.

Several times now I have found that the courtesy lights stay ON after all the doors are closed, and the dash switch is indeed off. This has caused the battery to drain.
I have opened and closed all doors numerous times and the light won't go off. I can't seem to find where the door switches are so that I can inspect them.
The last time this happened I was forced to remove the fuse, then the next day I put the fuse back in and the lights operated correctly.

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.

I've just returned from a late-night walk, where I discovered I'd left on the dome (interior ceiling) light in my 20-year-old car (soon to be replaced by a Prius c Two!) about a half-hour previously. I thought: if I hadn't noticed my mistake, tomorrow morning the battery would probably be dead!
Could this happen with a Prius c? Or is there a sensor that automatically douses any interior light(s) after, say, 15 minutes?

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.

This morning, my 2011 F150, told me that my rear driver side door was a jar on the center console. I opened and closed it several times using the inside handle and the outside handle. It affecting the battery since the interior lights stay on. Is there a way to reset / clean the sensor so that I don't have to take it into the Dealer?.. Their next appoint is mid next week.

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?
