C1241
ABS / stability-control fault code, listed for 1 vehicle line from Toyota. What it means on each one, with sources, and when the module is the cause.
What C1241 means
Low Power Supply Voltage Malfunction - +BS voltage below 9.5 V; trouble areas: ABS NO. 2 fuse, battery, charging system, harness, skid control ECU (brake actuator assembly)
On: 2005-2015 Toyota Tacoma (2nd gen)
Is it the ABS module?
Check the cheap things first: battery voltage and the main fuses for the ABS pump and module, the ground straps, the module connector (corrosion, a pushed-back pin) and, for wheel-speed codes, the sensor and its wiring at each wheel. If those are good and the code returns as soon as it is cleared — or the scan tool cannot talk to the ABS module at all — the module itself is the likely cause, and that is what we repair.
