Hey what's up,

My ABS light, power steering light, LDW light, FCW light, BRAKE light, and traction control light started lighting up in my 2013 Accord Coupe EX-L V6.
Sometimes just the traction control light and power steering light show up. Then the FCW and LDW show up down the road. Sometimes all of the lights go off after I have driven a little ways, or they don't light up when I start the car, but then they light up after some driving. The lights are sporadic. Like there is a bad/ loose connection.
Today, I went for an oil change at the dealership and had a diagnostic performed. "ABS - Hydraulic Control Assembly" and its going to cost me around $1,400.
This car has had ABS sensor issues in the past after I installed coilovers. I pinched a wire and I had to replace the sensor with the wire, but the problem went away. On a separate diagnosis in the past, they said the PCU was the problem and they were wrong. (I was refunded) I replaced the key fob and the problem of the push start and keyless entry went away. That was a separate problem and I am just saying, just because.
Before I went to the dealership for a diagnosis, I thought I had a bad ABS sensor somewhere and I remembered when I put the replacement ABS sensor in, I didn't put any dielectric grease and thought that could possibly be the problem. I ordered some Honda dielectric grease and applied it to all of the ABS sensor plugs to make sure none of the plugs could be having a connection issue. & because I forgot which specific single ABS sensor I replaced. Regardless, I put a very miniscule amount, I didn't go crazy with the dielectric grease.
Now, the only thing I can think to try is to pull the plug to the ABS Hydraulic control module, clean it, and then put a little dielectric grease before plugging it back in.
Or, I could get this part from a junkyard and replace it myself, but then I run the risk of the diagnostic being wrong and the problem continuing... So now I can bite the $1400 bullet, or I can research the problem more and talk about all of my options here.

Let me know what yall think, thanks!

 

I have been thinking.
My brakes are about due for a change. I could get the brakes changed and the fluid changed too. I think changing the brake fluid could possibly fix this issue. I checked the brake fluid and it wasn't exactly low, but it wasn't full to the max either. It isn't very clean looking and I think it could benefit from a fluid change. I'll let you know how it goes.

 

Alright, well I got my front brakes changed. I spoke with a guy at firestone and he seemed confident that changing the brake fluid would not help. I changed the brake fluid about 5 months ago anyways. It is looking like I have a bad part. The dealership wants a good amount to fix it. I looked online and found the part brand new OEM for around $900. It is an expensive part. I could also go the eBay route and get a used part. But, I run the risk of getting a faulty part with that route.
Then again, it seems to work for longer periods of times now. "Work" as in all of the dash lights go off and act normal. Maybe it will start working by itself... Maybe I just think that....
If I end up changing the brake fluid, I will report back.

 

FWIW that module has a pretty high failure rate. Ive replaced a few dozen of them. Thats not to say this is your issue,but as someone in the field,Im telling you its not unusual.

I would definitely go new over used either way.
