2003 infiniti 135 slip, tcs off light and check engine light came on after I pressed the TCS button due to curiosity and now it won't go off. Car also now hesitates when I try to turn it on

SOURCE: TCS/SLIP & Check Engine Light Warning

TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.

Check your brake fluid first. If that is low, top it off and recheck. If its ok, than you will need one of the rear ABS sensors. You will need to plug it in and find out which side it is. That's really the only ABS issue that car has. One of the rear ABS sensors fails.

i dont see any such code 1118, BUT, 1526/1540 is classic. 1526 is the vent solenoid circuit, and 1540 is the abv. these solenoids live on the back of the motor, right next to the egr valve. there is a row of 4, you are concerned with 2 and 4, going from right to left. i would first replace both, since they tend to go out around the same time. they control the abv, which controls boost. if this valve/circuit is not operating correctly, the pcm puts the car in "limp home" mode; will not rev over 3k, and tcs off/tcs lites come on. if you want to, ohm the solenoids when hot. normal is about 26, above 30 or 0, and they are bad. but from your description, i know they are bad.

I had the same code/symptoms a few weeks ago. Dealer did a nice job checking through all the details. Replaced the egr too, but no improvement. Finally found one cylinder not firing correctly (not the same pressure as the other cylinders.) Dealer did a value clean/adjustment, for about $250, and the problem has been gone for about a month now. We are also getting about 15% better mileage.

Hope this helps.
