C0241ABS Warning Lamp Control Circuit
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- None of the reachable J2012 tables contain C0241, and a warning lamp meaning is documented nowhere. GM's PIP5094 keyword list includes the number; AA1Car's table of GM ABS codes names it EBCM Control Valve Circuit. Saab used it in the TC/ABS 5.3 system of the first 9-5 model year, 1998, for a bad engine torque limitation signal: if the Trionic engine module has a torque control fault, a break in that line or the brake module carries the wrong engine variant, the engine side sends a fixed 96 percent pulse ratio and traction control shuts down with the TCS OFF lamp lit. The lamp in the title is required by FMVSS 135, which demands a brake warning indicator for any electrical failure of the antilock system. Check which system and maker stored the code before testing anything.
