DTC 15

DTC C1015 (No.15): G Sensor Circuit

Wiring Diagram










DTC Detecting Condition

While a vehicle is at stop or running, if the potential difference between the sensor signal terminal "E15-11" and the sensor ground terminal "E15-13" is not within the specified voltage value, or if the signal voltage while at a stop does not vary from that while running, this DTC is set.

Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the DTC and check again.

NOTE:

When ABS hydraulic unit / control module assembly for 4WD vehicle is installed to 2WD vehicle, this DTC is set. Before preforming the INSPECTION as follows, check part number for supply of ABS hydraulic unit/control module assembly referring to parts catalogue.

DTC Troubleshooting

1.
Is G sensor installed floor securely?
YES
Go to Step 2.
NO
Tighten sensor or bracket screw securely. If not, using new screw.

2. Ignition switch OFF.
Remove G sensor with bracket.
Check for proper connection to G sensor.
If OK, then check G sensor referring to G Sensor Inspection (for 4WD Model).

Is it in good condition?
YES
Go to Step 3.
NO
Replace G sensor.

3. Disconnect connectors from ABS hydraulic unit/control module assembly and G sensor.
Check for proper connection to ABS control module at terminals "E15-11" and "E15-13".
If OK, then turn ignition switch ON and measure voltage between "GRN/ORN" terminal of sensor connector and body ground.

Is it 10 - 14 V?
YES
Go to Step 4.
NO
"GRN/ORN" circuit open.

4. Measure voltage between "ORN" terminal of sensor connector and body ground.

Is it 0 V?
YES
Go to Step 5.
NO
"ORN" circuit shorted to power circuit.

5. Ignition switch OFF.
Check that "ORN" circuit is free from open or short to ground and "BLK/ORN" circuit.

Is it in good condition?
YES
"BLK/ORN" circuit open. If circuit is OK, substitute a known-good ABS hydraulic unit / control module assembly.
NO
"ORN" circuit open or shorted to ground or "BLK/ORN" circuit.
