DTC B1175: Fuel Level Sensor (Fuel Gauge Sending Unit) Circuit

NOTE: If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A

1. Clear the DTCs with the HDS.

2. Turn the ignition switch to LOCK (0) and then back to ON (II), or press the engine start/stop button to select the OFF mode and then the ON mode.

3. Check for DTCs with the HDS.

Is DTC B1175 indicated?
YES -
- With SH-AWD: Go to step 4.

- Without SH-AWD: Go to step 8.


NO - Intermittent failure, the fuel level sensor circuit is OK at this time. Check for loose or poor connections.


4. Test the fuel gauge sending unit and the secondary fuel gauge sending unit. Fuel Gauge Sending Unit Test

Are the fuel gauge sending units OK?
YES - Reconnect the sending units, then go to step 5.

NO - Replace the affected fuel gauge sending unit(s). Fuel Pump/Fuel Gauge Sending Unit Replacement


5. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

6. Without disconnecting the connectors, measure the voltage between terminals No. 2 and No. 22 of the gauge control module 32P connector and terminals No. 1 and No. 3 of the fuel gauge sending unit 4P connector.

Is there less than 0.2 V?
YES - Go to step 7.

NO - Repair the loose connection, high resistance, or open in the PUR or ORN wire between the gauge control module and fuel gauge sending unit.






7. Measure the voltage between fuel gauge sending unit 4P connector terminal No. 3 and secondary fuel gauge sending unit 4P connector terminal No. 1.

Is there less than 0.2 V?
YES - Replace the gauge control module. Service and Repair

NO - Repair the loose connection, high resistance, or open in the YEL wire between the fuel gauge sending units.






8. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

9. Test the fuel gauge sending unit. Fuel Gauge Sending Unit Test

Is the fuel gauge sending unit OK?
YES - Go to step 10.

NO - Replace the fuel gauge sending unit.


10. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

11. Disconnect the fuel gauge sending unit 4P connector. Fuel Pump/Fuel Gauge Sending Unit Replacement

12. Disconnect the gauge control module 32P connector.

13. Connect fuel gauge sending unit 4P connector terminal No. 3 to body ground with a jumper wire.






14. Check for continuity between gauge control module 32P connector terminal No. 2 and body ground.

Is there continuity?
YES - With SH-AWD: Replace the gauge control module. Service and Repair
Without SH-AWD: Go to step 15.

NO - Repair open in the wire.






15. Disconnect the secondary fuel gauge sending unit 4P connector. Secondary Fuel Gauge Sending Unit Removal/Installation

16. Connect secondary fuel gauge sending unit 4P connector terminal No. 3 to body ground with a jumper wire.






17. Check for continuity between gauge control module 32P connector terminal No. 2 and body ground.

Is there continuity?
YES - Replace the gauge control module. Service and Repair

NO - Repair open in the wire.
