I'm throwing the following codes but the description close to useless. Any ideas on what can be causing these?

C0240: PCM Traction Control Not Allowed (ETS)

C0041: Right Front Wheel Speed Circuit Range Performance

C0036: Left Front Wheel Speed Circuit Range Performance

Anyone?

The C0240 set because of the other two. Those indicate a problem with the front wheel speed sensors. Check for bad connection at brake control module or the wiring going to each front wheel. I see alot of roddent damage to wheel speed harnesses where I am, they love the taste of GM wires.

I would second checking the wiring on that. Mainly because I had an ABS Light on another vehicle and after replacing the hub I realized a connector was unplugged to that wheel speed sensor.

I have the C0240 code but that's the only one. HPTuners displays it like this

'Brake C0240 Immature History' I can NOT clear that code. Allegedly HPTuners can't clear BCM codes and so that code can only be cleared by a Tech2?

My Traction control will work then stop, then work, then stop. Loose harness?

If so, where should I look? Wheel sensor???? Is there a wiring harness or ground wire DIRECTLY related to the traction control PCM? Thanks!

I kno this is a old thread but I'm having these codes pop up after a heads, cam and stall swap I got a circle d 3600 stall and it seems like it doesn't wanna get out of first without me manually doin it from 1 to 2 I haven't gotten it tuned yet I just got the car back last night but I noticed it when I was babying it back home
