DTC C1241 / 41 IG Power Source Circuit
CIRCUIT DESCRIPTION
This is the power source for the ECU, hence for the CPU, and ABS actuator.
DTC No. DTC Detecting Condition Trouble Area
Detection of any of conditions from 1. through 3.
1. With vehicle speed at 3 km/h or more, IG1 or +BS termi-
nal voltage is 8.5 V or below for 10 sec. or longer.
S Battery
2. With IG1 terminal voltage at 8.5 V or below, ABS sole-

INSPECTION PROCEDURE
1 Check ECU-IG fuse.
Instrument Panel J/B PREPARATION:
Remove ECU-IG fuse from Instrument Panel J/B.
CHECK:
Check continuity of ECU-IG fuse.
OK:
Continuity
ECU-IG
F08570
NG Check for short circuit in all the harness and
components connected to ECU-IG fuse (See at-
tached wiring diagram).
OK
2 Check battery positive voltage.
OK:
Voltage: 10 - 14 V
NG Check and repair the charging system
(See page IN-29 ).
OK
3 Check voltage of the ECU IG power source.
In case of using the TOYOTA hand-held tester:
PREPARATION:
(a) Connect the TOYOTA hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand-held tester main switch ON.
(c) Select the DATALIST mode on the TOYOTA hand-held tester.
CHECK:
Check the voltage condition output from the ECU displayed on the TOYOTA hand-held tester.
OK:
"Normal" is displayed.
