DIAGNOSTICS - ABS WITH EBD & BA & TRAC & VSC SYSTEM
DI6BM-03
DTC C1241 / 41 IG Power Source Circuit
CIRCUIT DESCRIPTION
DTC No. DTC Detecting Condition Trouble Area
Detection of any of conditions 1. through 4.:
1. Vehicle speed is 3 km/h (1.9 mph) or more and voltage
of ECU terminal IG remains below 9.5 V for more than
10 sec.
2. While the condition that the ABS SOL relay is ON con-
tinues, ECU terminal IG1 voltage becomes 9.5 V or less,
S Battery
and the condition that the contact point of the ABS SOL
C1241 / 41 S Charging system
relay is OFF continues for 0.2 sec. or more.
S Power source circuit
3. The condition that ECU terminal IG1 voltage is more
than 17.0 V continues for 1.2 sec. or more.
4. While the ABS SOL relay outputs ON signal, ECU termi-
nal IG1 voltage becomes more than 17.0 V, and the
condition that the contact point of the ABS SOL relay is
OFF continues for 0.2 sec. or more.

DIAGNOSTICS - ABS WITH EBD & BA & TRAC & VSC SYSTEM
INSPECTION PROCEDURE
1 Check battery positive voltage.
OK:
Voltage: 10 - 14 V
NG Check and repair the charging system.
OK
2 Check ECU-IG fuse.
Driver Side J/B PREPARATION:
Remove the ECU-IG fuse from the driver side J/B.
CHECK:
Check continuity of the ECU-IG fuse.
OK:
Continuity
ECU-IG
NG Check for short circuit in all the harnessers and
components connected to ECU-IG fuse (See at-
F13788
tached wiring diagram).
OK
3 Check voltage of ECU IG power source.
In case of using the hand-held tester:
PREPARATION:
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tester main switch ON.
(c) Select the DATALIST mode on the hand-held tester.
CHECK:
Check the voltage condition output from the ECU displayed on the hand-held tester.
OK:
"Normal" is displayed.

ON In case of not using the TOYOTA hand-held tester:
PREPARATION:
V16
V19 Remove the skid control ECU with the connectors still con-
8 nected.
7
6
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals IG1 (V19 - 7) and
31 16 GND (V16 - 6, 31, V19 - 8, 16) of the skid control ECU.
F13777 OK:
Voltage: 10 - 14 V
OK Check and replace skid control ECU.
NG
4 Check continuity between terminal GND of skid control ECU connector and body
ground.
LOCK PREPARATION:
V16 V19
Disconnect the connectors (V16, V19) from the skid control
ECU.
CHECK:
8 Measure resistance between terminal GND (V16 - 6, 31, V19
- 8, 16) of the skid control ECU harness side connector and
31 body ground.
6 OK:
16
F13783 Resistance: 1 or less
NG Repair or replace harness or connector.
OK
Check for open circuit in harness and connector between skid control ECU and battery
(See page IN-28 ).
