2009 Acura MDX Tech - Rear Right Door
 

Hi
I have a 2009 MDX with ~ 80K on it.

I noticed a weird issue going on with the rear right passenger door. When the door is open, the central panel (that displays open doors/tail gate) doesn't show that the rear right door is open. Also, I am able to centrally lock the car even though the rear right door is open.

Any advice on what might be causing this ?

Appreciate your help in advance

Thanks
Raj

the sensor is stuck closed

Thank you. How to find it and fix? Can you provide some insight please?

Open the door, look for the sensor plunger, it's a little black rubber-covered switch. See if it's just stuck in and if you can use your finger to 'unstick' it. Then report back

@thoiboi , thank you for the direction. I checked the sensor plunger and could not find any switch covered by the plunger. When I squeezed the plunger, it was just going in & out free like a feeding bottle nipple. (apologize for this reference, as I couldn't find any better appropriate comparison).

I am attaching the picture herewith as well, for your reference. Please advice what I can do to fix this. I am sure if I go to the dealer, it will cost me a fortune.

Could be just a bad switch, part number is there, Amazon link is slightly more expensive but includes shipping:

Thanks a lot.

Let me try this out and update you. May take a few days, thoiboi.

hello thoiboi
At last, I received the replacement part last week and had the exercise done. The part was broken and was way deep inside the body. Oh god, it was a hassle to pull the cord out and remove the broken piece and put on the new one. Took almost an hour with very limited tools.

Anyways, I thank you a lot for the timely responses and directions.

Not to overwhelm you, since this past week, I have been getting the below three messages ;

1. Vehicle Stability Assist: 67
2. Trailer Stability Assist: 69
3. All-Wheel Drive: 77

The All-Wheel Drive alert is very transparent as I can clearly see that no power being transmitted to the rear wheels.

Any idea what is causing this?

Thanks

Typically a bunch of codes popping up at the same time can be attributed to a bad battery / low voltage.

In your case however, it may be an ABS /Wheel sensor that is malfunctioning that is causing all 3 of those codes to come up at once.

Is the battery old? If it's been a few years, you can try replacing it and seeing if the codes clear after replacement.

Thanks again thoiboi. The battery is close to 2 years, I believe. Is that too old, as per the standards?
