DESCRIPTION
If there is a problem with the brake actuator assembly (skid control ECU) power supply circuit, the skid
control ECU outputs the DTC and prohibits the ABS operation with the fail safe function.
If the voltage supplied to the IG1 terminal is not within the DTC detection threshold due to malfunctions in
such as the battery and alternator circuit, this DTC is stored.

INSPECTION PROCEDURE
HINT:
After steps 1 and 2 are completed, start the inspection from step 3 when using the intelligent tester, and
from step 4 when not using the intelligent tester.
DTC C1241/41 Low Battery Positive Voltage
DTC No. DTC Detection Condition Trouble Area
C1241/41When any of the following is detected:
• Vehicle speed is 3 km/h (1.8 mph) or
more and IG1 terminal voltage is 9.5 V or
less for at least 10 seconds.
• While the solenoid relay is ON, the IG1
terminal voltage is 10 V or less and the
relay contact is open solenoid fault
detecting conditions are established.
• Voltage of ECU terminal IG1 remains at
more than 17 V for 1 second or more..• Battery
•ECU-IG fuse
• Charging system
• Power source circuit
