Any way to test ABS sensors?

[Sp33dyote5.0]

Yes you can do that and more with Forscan but you gonna need an obd scanner that has an ms/hs switch. Im using the OHP wifi version and it works great but theres other out there that will work like the mx and lx mentioned here. When using the scanner in MS is gonna pull all the internal codes from the ABS module which is what you want and also this mode is what allows you to datalog the abs wheel speed and much more. I had the same code your getting and it turned out to be the driver side rear wheel hub is bad. All those codes you see in the picture were stored inside the ABS module and you wont be able to see them with a basic Hs scanner.

Thank you very much for the info I have a MX now with Forscan. I didn't know about the graph to show what the sensors are doing. These are the codes I got:

DTC in PCM
P061A:00-68

DTC in FDCIM
U3003:16-AC

DTC in OCS
U0401:00-28

DTC in ABS
U0140:00-68, C0051:67-68, C0039:07-68

DTC in RTM
U0401:00-28

DTC in RCM

U3003:16-08, B00A0:68-08, U0401:00-08

DTC in PSCM
U0401:00-08, U0415:00-08, U3003:16-08

DTC in IPC
P1535:01-08, U0415:00-08, U0415:81-08, U3003:16-08

DTC in GPSM
U3003:16-08

The one that really caught my eye was the C0039:07-68 right rear tone, I think the others are power disconnected errors due tot the PCM cutting those systems. Before I would feel the clunking before all the systems get cut then it drives smooth. I took the sensor off of that wheel and the car drives smooth without the clunking, I just has the errors. I ordered a new sensor since it's only $11 and if that doesn't work I will get the hub assembly.

I tried a new speed sensor and it dint fix the problem. Some people have reported a fix by replacing the axle ring but usually C0039 is more than likely the wheel hub. If you want to test the abs speed sensor just switch the left rear to the right and vice versa and go ahead and data log the speed via Forscan. You dont have to buy a new one because the left and right are the same.

I ordered a sensor already, it should be here friday. Im really hoping its just that so i wont have to spend $100 on a hun assembly. The weird thing is that i get the jerking with all the systems on but as soon as the car turns them off it stops. Im thinking if it was something mechanical wouldnt it keep jerking systems on and off? Also i have DSS axles, not sure if that matters.

Jerking on take off or while driving? I would get some jerking on take off if i dint slip the clutch a little. Reason been that the abs also turns off the clutch take off assist and hill assist.

While rolling with the clutch engaged there will be jerking/pulsing and as soon as the car cuts everything it stops.

I took that sensor off it doesnt jerk at all.

Also before it cuts everything the brakes feel like crap. Feels like they are locking up with the slightest pressure and when the car cuts the system brakes go back to normal.

Thanks for the help and advice everyone. I looks like the new sensor fixed the problem. It didn't happen right away but after driving a few miles all of the lights went off and have not reappeared.

Nice job!

Which sensor did you replace ? Right rear? Left rear ?

I think it was rear right. Its been so long ago. Its been good ever since.

Gotcha Thanks ! I’m having the same issue . Did a pull and a couple seconds later the abs and advanced trac light came on along with the U0415 code

No problem. I think it was FORSCAN lite that i used which the live data was showing the abs readings being was off which led to me changing the sensor.
