DTC C1015: G Sensor Circuit (4WD Model): Troubleshooting

DIAGNOSIS PROCEDURE

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 Disconnect G sensor connector and ABS hydraulic unit / control module connector with ignition switch turned OFF. Check for proper connection to G sensor connector and ABS hydraulic unit / control module terminals of "E08-3" and "E08-6". 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 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 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 2Ω?	Go to Step 6.	"GRN/BLK" and/or "GRN/YEL" wire circuits in open or high resistance.
6	G sensor ground circuit check Connect ABS hydraulic unit / control module connector with ignition switch turned OFF. 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.
