My car Mitsubishi Sigma 1997 3000 cc has a problem, wherein the SRS and ABS lights stay on, even after the car starts and moves. I had it reset by the diag tool in the workshop, the SRS light went off but when it starts again it still stays on. While for the ABS, the diag tool was not even capable to trace what the problem is and it still stays on. Tried to unplug and plug again the ABS sensors, but didn't help. The brake liquid is normal and okay. Does anyone experience it and know how to fix it?
