4E-18 ABS:
DTC C1015: G Sensor Circuit (4WD Model)
S6RW0C4504013
Wiring Diagram
Refer to “Wiring Diagram” under “DTC C1013: Control Module Mismatch”.
DTC Detecting Condition and Trouble Area
NOTE
When a vehicle is lifted up and its wheel(s) is turned, this DTC is set.
In such case, clear the DTC and check again.
Troubleshooting
DTC Detecting Condition Trouble Area
• G sensor signal voltage is out of specified range.
• Vehicle behavior and G sensor signal is disagreed. • G sensor
• G sensor circuit
• ABS control module
Step Action Yes No
1 Was “ABS Check” performed? Go to Step 2. Go to “ABS Check”.
2 Is G sensor installed its bracket securely? Go to Step 3. Tighten G sensor bolt
and recheck.
3 G sensor check
1) Disconnect G sensor connector and ABS hydraulic unit /
control module connector with ignition switch turned
OFF.
2) Check for proper connection to G sensor connector and
ABS hydraulic unit / control module terminals of “E08-3”
and “E08-6”.
3) If OK then check G sensor referring to “G Sensor
Inspection (4WD Model)”.
Is it in good condition?
Go to Step 4. Replace G sensor.
4 G sensor power source voltage check
1) Turn ignition switch to ON position and measure voltage
between “GRN/ORN terminal of G sensor connector and
vehicle body ground.
Is it 10 – 14 V?
Go to Step 5. “GRN/ORN” circuit
open.
5 G sensor signal circuit and ground circuit check
1) Measure resistance between following terminals.
• Between “E08-3” terminal and “GRN/BLK” terminal of
G sensor.
• Between “E08-6” terminal and “GRN/YEL” terminal of
G sensor.
Is each resistance less than 2
Ω
?
Go to Step 6. “GRN/BLK” and/or
“GRN/YEL” wire circuits
in open or high
resistance.
6 G sensor ground circuit check
1) Connect ABS hydraulic unit / control module connector
with ignition switch turned OFF.
2) Turn ignition switch to ON position and measure voltage
between “GRN/BLK” terminal of G sensor connector and
vehicle body ground.
Is it 0 V?
Substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck. “GRN/BLK” circuit to
power circuit.
