C1241

DTC C1241 Power supply voltage error

Description of functions

If there is a malfunction in the power supply circuit, the skid control computer (brake actuator ASSY) outputs a diagnostic code and prohibits the operation by fail safe function.
If the voltage to the +BS terminal is not within the range of DTC detecting conditions due to a malfunctioning power supply or charging circuit (including battery and alternator circuits), this code will be stored in memory.
When the voltage to the +BS terminal returns to normal, this diagnostic code will be cleared.
