I took the time to remove the covering on the hood latch to see what it looks like under there. I’m assuming that the micro switch is what tells the car whether the hood is open or closed. Any suggestions on how I could test the wiring, connector, or switch? View attachment 60105

If you have AlfaOBD the BCM System Status logs will show the condition of the hood (open/closed) and the voltage in either position. Getting any change in those values should let you know if the switch itself is working. If not, you could jump the terminals to close the circuit and eliminate the switch from the circuit (this should make the reading go from open to closed)

I unplugged the hood latch sensor and the message finally appeared in the gauge cluster. I’m assuming this means that the car is getting information from the switch properly but the switch itself is not working right. This is odd to me because the entire latch assembly was replaced at one point. I noticed that the switch itself is held in with just one screw. Is it possible to obtain the switch by itself?

OK, so you've pretty much isolated it to the switch and/or the latch itself. Is it stuck closed (the switch itself)? Lubrication with some dielectric grease and cycling the mechanism might fix it. If you can disassemble and pull a part number off the switch itself you might be able to find an exact replacement on this site:

How could it be the latch itself? It’s only the switch that works with the hood indicator, no?

Unknown, does the latch need to mechanically engage the switch? If the latch fails to engage the switch (stuck part keeping the circuit closed) then that is what I'm referring to. I haven't looked at it myself but essentially what I'm getting at is to ensure all mechanisms are functioning properly before replacing parts.

Did you replace the latch yourself? Does the switch/sensor look new? Just curious if maybe the latch was replaced and the old sensor was used? Never dealt with it, so don't know it a new switch/sensor just automatically comes with all the latches? Maybe aftermarket latches (if that's a thing) don't come with the sensor? Probably not a lot of help there, but thoughts that are going through my mind...

I had considered this. I was not the one that replaced the latch.

I did a little digging, and it appears that you can order the latch with or without the switch/sensor. On the Mopar parts sight, you can get the latch without the sensor/switch (68237954AF) for about $34 or with the sensor/switch (68237953AF) for about $55. Unfortunately at this point it would appear that it's possible that the same switch could have been reused when the latch on your van was replaced. I have yet to find a source for just the switch however.

That seems to be typical across MOPAR brands with the primary purpose being to disable remote start and/or to stop HV charging. It can be bypassed by grounding a PIN in the BCM, jumping the switch or shorting the circuit to ground anywhere between the two.

I checked to make sure that the latch is properly engaging the switch and it is.

I was able to completely remove the switch assembly from the latch and unfortunately it seems that the switch is sealed into the assembly itself. I don’t believe replacing the switch alone is possible. If anyone is interested I believe the switch is a Panasonic ASQ series.

Looks like it's just press fit in. If there's a part number on the other side you can probably replace just the teal switch. Conversely you can leave the latch off and plug back in just the switch and see if it triggers the hood ajar by manipulating it manually.

i cant find this under the hood? I keep getting hood open notification.

There is a spot for it above the driver headlight but i dont see it there.

Your vehicle may not have that type of hood switch. It's likely co-located with the hood latch.

Well I'm getting open hood notification non stop and I'm wondering if that's why immy alarm keeps going off randomly too. It's gotten to point where the horn sound has changed from exhaustion.

That's bad, it will kill the battery. The alarm is tied to the hood latch.

Fantastic. So sick of this f in van

Ok. So do I buy that

sensor/switch (68237953AF) for about $55

Can I diy?

Yes, you can DIY. However, you may be able to repair your current switch. Sometimes, the little metal leaf spring just needs to be bent back into place/stretched out. That part number looks correct.

i just cleaned off my swtich ( found it) with electronics clearner and will see if alarms starts blaring in meantime ill go buy that other part(68237953AF)

What I'm referring too is the post above with this image...try pulling that metal spring contact leaf out or bending it straight again too.

 

[vdubpower]

when i manually push the latch down, it makes contact with strip and then compresses the button underneath
