(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GND1 CIRCUIT)
OK -- Continue to next step.
5. RECONFIRM DTC
(a) Reconnect the skid control ECU connector.
(b) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes.
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(e) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Reading and Clearing Diagnostic Trouble Codes.
Result:
HINT
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next
step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related
Diagnostic Procedures/Problem Symptoms Table.
B -- REPLACE BRAKE ACTUATOR ASSEMBLY See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Hydraulic Control Assembly - Antilock Brakes/Service and Repair/Removal
A -- CHECK FOR INTERMITTENT PROBLEMS See: Accessories and Optional Equipment/Antitheft and Alarm
Systems/Diagrams/Diagnostic Aids/How To Troubleshoot ECU Controlled Systems/How To Proceed With Troubleshooting
From 08/2009
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.
