Acura Repair Questions? Ask a Mechanic for Answers ASAP
My name is ***** ***** I would be happy to help. Let me try to research this code. As a Honda/Acura mechanic of 10 years this code looks very unfamiliar.
Hello. The thump and the code are not related. The thumping/pulsating is most likely a warped brake rotor. During heavy braking the rotor gets hotter than during normal braking and the hotter temperatures are likely causing the rotor to become disfigured which gets better when the rotor cools a little bit. That code, is one I have never seen before. I have searched through a technician database as well that strange things like that often end up in in search for explanation, and there was absolutely no mention of it there either. Could you possibly check for codes using a different scan tool?
Oh, so you have already determined the source of the thumping? I was unaware of that since it was not previously mentioned. As of now, it sounds now more like ABS activation, possibly a result of a bad tone ring or abs sensor? Have you scanned for ABS codes?
I figured you may be in the industry based on the fact that your scan tool is an ethos.
Please keep in mind that we only know what you tell us. We dont' know what you know, what you have done already, etc.
I don't think it's a snap-on code, but it's worth investigating I suppose.
I have owned a Modis for years, and on many occasions have been unable to obtain codes that my cheap auto xray was able to obtain. Just the way it goes sometimes. Check with another scan tool and let me know what you get.
Great. And check for ABS codes. I have a feeling one of your tone rings or ABS sensors may be bad/cracked causing the ABS activation.
The other scanner didn't pull up that odd code though, right?
Inspect all the tone rings and make sure they are all tight. A cracked one will be loose. Use your snap on scan tool and monitor the wheel speed sensors and when this happens, see if one of them seems to be acting different than the rest.
Did you get a chance to monitor the wheel speed sensors on your snap-on?
The issue was ABS activation while reversing out of your driveway, right? were you able to get it to do that again while watching the sensors on the scan tool?
it won't do it when your monitoring the abs sensors with the scan tool? When your coming to a stop, all the sensors read the same until your stopped?
