Customer Question
We just purchased a...

We just purchased a 2011 MDX. Not knowing about all the buttons (there are so many!) we didn't know what worked and not. Driving and reading the manual over the last 2 weeks, we have noticed that the comfort button that controls the ADS system just flashes when engaged. The manual also says that when in "S" sport mode there should be a SPORT display for a few seconds on dash same for when in COMFORT mode. Nothing shows on display. The ADS warning light doesn't come on either indicating a problem.

Mechanic's Assistant: Just to clarify, what are the exact lights you're talking about?

The comfort button on center console below gear shift and cupholders

Mechanic's Assistant: What is the model of your '11 Acura?

Yes with advanced tech package

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

We have a mechanic but he doesn't specialize in Honda/Acura. We have a 90 day warranty with the car but it doesn't cover everything so we are trying to figure out what could be the cause to tell our mechanic

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That seems to be the only problem we have. We are having the timing belt replaced since it doesn't seem to be done and there is 120,000 + miles on the car. Any help on the ADS would be appreciated as we never had a car with all this tech.

Looking for the cause and possible repair of the blinking comfort button light to take to get repaired. We will not be repairing it ourselves.
Customer reply replied 4 months ago
I cannot do a call but would like to know what the possible causes may be for the flashing comfort button. Dirty/bad sensors? the dash light that indicates a problem with the ADS doesn't come on so I don't know what is causing the flashing comfort button light.

Fuse looks fine
Mechanic for Acura: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 4 months ago

to be honest at this time You will need a Capable Factory scanner or equivalent to Read the Fault codes in the Modules needed and based on these faults we can pull up a Pin Point Troubleshoot and be Accurate ,If you get the Faults Read ,post them back here for me and I can Help You Further on it & we be Accurate other than that we end up throwing parts at it

as you can see we have several things involved ,if fuse we have a different issue ,.

With that said the mos common is the control unit or the Front acceleration sensor . but testing is needed ,this complicated system, so get the troubleshoot done at dealer using a dealer scanner and get faults code so we can pull up the correct troubleshoot and narrow down

We take it to our mechanic tomorrow for a new car checkup. I am disappointed though as I thought I'd get more than check the fuse. I even looked it up and there are 2 fuses for the ADS I checked both. But I will get back to you after we get the report from the mechanic.

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help.
