Default TCS OFF and ABS INOP

These lights keep coming on on the dash...

comp doesn't throw any codes

TCS and ABS seem to be working fine...TCS switch does nothing

What to do?

I don't have TCS but when my lights came on it ended up a loose ground on the driver fender well under the hood, have you tried that?

What were/are you doin when lights come on? I know from experience if you get repeated wheel spin w/ tcs turned on, like 1st-4th gears in the rain the tcs shuts itself down and the lights come on. Also check to make sure the tcs motor on the pass fender by the batt. is plugged in, that will turn tcs lights on

I'm sure somethings wrong with one of the two and the minor problem is tied them to one another. If you know somebody with ABS reading tool, or you can always pay a shop to read it but it usually cost a LOT more than a normal Check Engine Light Reading.

Your not getting a Check Engine light because ABS has it's own brain and will not trip the PCM's Check Engine light but it will trip its own ABS INOP light.

Also, check the traction control modules in the rear backing plates by the calipers. I installed a Strange 12-bolt with the ABS/TCS option, and immediately threw the same lights on the dash. TCS switch wouldn't work. At first Strange was no help, one of my buddies that was experiencing the same issue recommended to check the TCS modules. This ended up being the problem, one of yours might be bad. What the issue with the Strange and TCS was: the modules were sitting too far in the backing plate to pick up the teeth on the reluctor wheel throwing the readings off. I put a rubber o-ring around the module to space it out just a bit and this seemed to fix the issue. Every once in a blue moon it would disable, so I'm going to add some solid washers/spacers to see if this fixes the issue permanently.

I've had this problem for months randomly. The snap on scanner says check wiring to wheel sensors. I just replaced my hub and problem solved

Yup, bad wiring or dirty/defective wheel speed sensors...

I've been having this problem as well, intermittently. When on the interstate, and I finally actually notice it, I just shift to neutral (M6) turn off the car, and restart it, and they are gone. Happens once a week or so.

I guess I need to pressure wash the **** outta the rear wheel area?
Where are the sensors located?

The sensors are located on the back side of the hubs, bottom. 10mm bolt holds them in, they just slide out.
