(a) Disconnect the ECU connector.
(b) Measure the resistance of the wire harness side connector.
Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. RECONFIRM DTC
(a) Clear the DTC See: Transmission and Drivetrain/Transfer Case/Testing and Inspection/Reading and Clearing Diagnostic Trouble
Codes.
(b) Start the engine.
(c) Drive the vehicle, accelerate to a speed of 3 km/h (2 mph or more, and check if the same DTC is output.
Result:
HINT
Reinstall the sensor, connectors, etc. and restore the vehicle to its prior condition before rechecking DTCs.
B -- CHECK INTERMITTENT PROBLEMS
A -- REPLACE 4WD ECU ASSEMBLY

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1241: Low Power Supply
Voltage Malfunction
C1241 - Low Power Supply Voltage Malfunction
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (housed in the actuator assembly) stores this DTC and the fail safe
function prohibits ABS operation.
This DTC is stored when the IG1 terminal voltage deviates from the DTC detection condition due to a malfunction in the power supply or charging
circuit such as the battery or alternator circuit, etc.
The DTC is cleared when the IG1 terminal voltage returns to normal.
