DTC C1015: G Sensor Circuit (4WD Model)

Wiring Diagram
Refer to "Wiring Diagram" under "DTC C1013: Control Module Mismatch".
DTC Detecting Condition and Trouble Area
DTC Detecting Condition
• G sensor signal voltage is out of specified range.
• Vehicle behavior and G sensor signal is disagreed.
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
Step
1 Was "ABS Check" performed?
2 Is G sensor installed its bracket securely?
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?
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?
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
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?
