VEHICLE BEGAN THROWING BRAKE ECU CODE 136 66 7 AND TCS LIGHT REMAINS ILLUMINATED. WHEN THIS CODE IS ACTIVE AND TCS LIGHT IS ILLUMINATED VEHICLE SEEMS TO REQUIRE MORE BRAKING DISTANCE, AND MORE BRAKE AIR PRESSURE APPLIED TO GET THE SAME BRAKING RESULTS AS WHEN THE CODE IS NOT ACTIVE NOR IS THE LIGHT. UNDER ACCELERATION DURING CORNING (WHILE CODE ACTIVE AND LIGHT ILLUMINATED) DRIVE WHEELS WILL SPIN AND TRACTION CONTROL WILL NOT KICK IN TO AVOID WHEEL SPIN (COULD POSSIBLY CAUSE JACK KNIFE). WHEN SERVICE BRAKES APPLIED (WHILE CODE IS ACTIVE AND LIGHT ILLUMINATED) TRAILER ABS LIGHT ILLUMINATES THE ENTIRE DURATION SERVICE BRAKES ARE APPLIED (VARIOUS TRAILERS, VARIOUS MAKES, VARIOUS YEARS).
