So I went to work at 230pm, parked in a gravel lot on a slight decline so I used my E-brake as well as the regular brake. When I left work at 1030 and started the car, bright orange yelowish warning (check sh-awd system) flashed on the infotainment screen and remained lit. I have no idea why this is hapening. I treat the cacar like my precious with no rough driving and the gas never gets below half ttank and I never drive it more than 70 miles an hour. Only mod is the addition of the nav which was done by a dealer a year ago. Any ideas are welcomed thanks.

 

Differential fluid level or battery.

 

Thanks for the rapid response but is that a dealer fix or somthing i can do myself. mechanical skill of a level 4 out of 10.

 

It's something you can do yourself if you have a socket wrench and a breaker bar. The diff fluid fills up to the bottom of the fill hole. Any more and it pours out of the hole. Take out the fill bolts and check the fluid level.

When was the last time it was changed? You may just want to do a whole drain and fill anyway.

 

I am at the deadealer now abd they are charging me $118 to do a diagnostic even tho I told them that I am prety sure its the differential fluid since my battery is only 6 months old. stay tuned for updates as they come to me.

 

$118 is normal for them to look at it. If they do work, it should go into the price of labor/parts. Don't rule out the battery just because it is 6 months old. They should have a good battery to check with if necessary.

 

Since the battery on these cars die so quickly is it possible to install an extra battery in the trunk to power the electrinics or aleve some of the strain from the one under the hood

 

Not worth it. Battery should last 3 yrs unless you got a bad one or you have a short somewhere.

Installing 2nd battery in trunk would require running thick cables up to front of car.

 

I'm am soooo f ing pissed. After two and a half hours they told me they couldn't figure out why the SHAWD light is on and wanted to charge me $300 more to take the back seat out and inspect sensors. I told them no and they charged me $106 for diagnostic without diagnosing anything. I'm fortunate in CT to have multiple Acura dealers within 30 miles so I'm going to my main dealer on Tuesday

 

Once my AWD light went on and all of my dash lights/gauges turned off. No other problems. Car was fine other than that. Checked fuses but nothing. I disconnected the Battery and reconnected and everything was then fine.

Couldnt tell you what the problem was. I'd always disconnect and reconnect the batt, as a first place check (other than fuses). You never know.

 

I am going to try disconnecting the battery in the morning and see if anything changes.

 

Did they give you the list of codes that were stored in the computer? A lot of times a battery code will be present and buried underneath the other codes.

I agree with getakey. A secondary battery would be a waste of time, money, space, and weight. Batteries bought from auto stores carry a minimum warranty and a pro-rated warranty after that.

 

They did give me a code (82-2) they said it was the only code showing up.

 

I just looked up that code and it says

82-2 Right Search Coil Sensor (open or short)

Does anyone know if this is going to be an expensive fix?

 

I looked up the code on this link and it was actually very helpfull but I still don't know how much the fix is expected to be.

Are you still getting the SH-AWD error? Surely you know about how any sort of weakness in a battery can propagate into many different error codes in the RL. Did the dealer check everything with a known good battery?

 

You should have let them remove the rear seat because that is where the sh-awd control unit is located and that code requires checking in between the control unit and the search coil on top of the rear diff. As long as that search coil connector is not soft set or disconnected all together, it could be a faulty SH-AWD control unit, a faulty wire, or may in fact require replacement of the rear diff side case depending on what their diag shows up...U have an extended warranty?

 

Not with Acura but I do have an aftermarket warranty hopefully it covers it this sounds like an expensive fix

 

Just got a full diagnostic an it appears to be a short in the right side serch coil and the whole unit needs to be replaced. Anyone know a part number for this or where I can get it for cheaper price?? Please help!!!

 

You said you have an extended warranty...cash in on it. This should definitely be covered.

 

Unfortunately the crappy waranty denied the coverage . The dealer wanted to charge me $900+ for the part and $150 for install. I was able to find the part online for $606 + $10 shipping. the part is called SH-AWD Control Unit part number 48310-RJC-A09, does nayone know how to install this item?

 

It's mounted behind your rear seat back...Just plug in and go but the dealer has to initialize it. You could always try and find one in the junk yard. These are not common to go bad.

 

thats why i dont believe its the control unit but whenever a dealer cant pin point an issue they blame it on the most expensive part to fix.I also read that the control unit would have to be progrmed by the dealer, is that true?

 

This is not the most expensive part. The search coil is actually built into the rear diff. If it has an open or short, the whole diff is gonna have to be replaced. Yes your dealer has to hook up the HDS to initialize it. I would just source the part and have them replace it for $150...because that should include initialization.

 

sOLLEx So the serch coil is built into the sh-awd control unit? Just want to make sure I get the right part because there is no return on electrical components. Can u validate that the part and part number I posted is for the issue with the error code 82-2.

 

No its built into the rear diff...the part number you listed is for the control unit. Like I said earlier, either one could be bad depending on what their diag shows.

 

Sounds to me like the dealer doesn't know for sure what is going on. Is there anyway to bind them to an agreement that if they don't fix the problem, they should reverse the work and charge nothing?

 

oo7spy. I totally agree because it has happened to me with another car. They misdiagnose and charged me to fix a problem that was not the source of the issue at hand. And when the problem continues they just point to something else and charge you to fix.

 

Your error code says search coil, not control unit. Because of this, I would source a used differential and replace the whole thing before I went with their idea, but it isn't my car.

 

From my understanding isn't the serch coil built into to the control unit? And as far as the control unit, the part number 48310-RJC-A06 48310-RJC-A07 48310-RJC-A08 has been replaced with 48310-RJC-A09. Dies this mean I can use either one of those discontinued ones since they are about $80 on eBay

 

I've already told you, the DTC could be caused by the search coil sensor inside the rear diff, the control unit or the wiring in between the two. All the tech is supposed to do is ohm out the sensor and check for continuity between the control unit and the sensor and its connector. If you don't trust what they are telling you, then get another second opinion...btw don't buy a discontinued part...that usually means they have counter measured parts in the newer one.

 

News updat!! Just purchased the SHAWD control unitized for $85 and have an appointment for tomorow at 3pm for install. By the way does anyone know if its legal for a dealer to deny service for installing parts that is it purchased at their high prices dealership. This sounds like a war against capitalism to me.

 

A service provider can deny service for almost any reason except race. Many shop's business model is built around their profit between invoice and list prices.

 

That's interesting to know. It's absolutely funny to me that a service manager would turn business away because customers chose to buy parts elsewhere at a cheaper price. Isn't that what this wonderful country is built in? Capitalism!!! Anyways it's there lost because there are four Acura dealers within 30 minutes drive from me that would gladly accept my business.

 

I honestly don't understand it unless your schedule is so booked that you can easily replace the business with some that is buying parts from you. If that is not the case, I guess they feel some people will submit and buy their parts.

I recently had my wife's CR-V brakes done. Brake place wanted $96 for pads. Picked up the exact same ones for $60 at the Napa store.

 

That's why retailers are a dying breed. The lack of willingness to to be competitive with online merchants will drive them out if business. The funny part about this particular acura dealership is that they didn't even have my part so they would of had to order it. I guess they wanted to tack on their own fees (smh greed!!)

 

Hey Top,

Let us know if the control unit fixes your problem. It's just weird that this happen to your RL which is an 08, low mileage, and I'm sure you treat her well. I know your problem is not common but at least we'll know what to do if we ever run into this probrem.

I am very surprise this is happening too. I'm pretty sure it's a lose wire or something but we will see tomorow afternoon.

 

I would say your dealer will install your part but just won't give you a 12 month 12k mile warranty on the part. I think you will be fine as long as they diagnosed it properly.

 

By the way this isn't the first time that particular service manager has behaved is such rude manner. A year ago he accused me of taking money out of his parts guys pension simply because I am looking out for my own self interest which is to save money any chance I get like everyother sensible person on the planet.
