DTC B1201: FUEL SENDER CIRCUIT FAILURE

G92510t16: CHECK THE VOLTAGE SUPPLY TO THE FUEL TANK ELECTRICAL CONNECTOR
1. Switch the ignition to the OFF position.
2. Disconnect the fuel tank electrical connector CA005.
3. Switch the ignition to the RUN position.
4. Measure the voltage at the fuel tank electrical connector between:
- CA005 pin 1, (WU) and GROUND
- CA005 pin 2, (WB) and GROUND

- Is the voltage greater than 10.5 Volts?

-> Yes
GO to Pinpoint Test G92510t17.

-> No
GO to Pinpoint Test G92510t18.

G92510t17: CHECK THE GROUND SUPPLY TO THE FUEL TANK ELECTRICAL CONNECTOR
1. Switch the ignition to the OFF position.
2. Measure the resistance at the fuel tank electrical connector between CA005 pin 3, (B) and GROUND.

- Is the resistance less than 0.5 Ohms?

-> Yes
GO to Pinpoint Test G92510t19.

-> No
GO to Pinpoint Test G92510t20.

G92510t18: CHECK THE VOLTAGE SUPPLY FROM THE INSTRUMENT CLUSTER
1. Switch the ignition to the OFF position.
2. Disconnect the instrument cluster electrical connector IP010.
3. Switch the ignition switch to the RUN position.
4. Measure the voltage at the instrument cluster connector between:
- IP010 pin 8 and GROUND
- IP010 pin 7 and GROUND

- Is the voltage greater than 10.5 Volts?

-> Yes
REPAIR the relevant circuit. CLEAR DTC. TEST the system for normal operation.

-> No
INSTALL a new instrument cluster. CLEAR DTC. TEST the system for normal operation.

G92510t19: CHECK THE RESISTANCE AT THE FUEL LEVEL SENSORS
1. Remove the fuel tank.
2. Disconnect the fuel sensor electrical connectors:
- FT002
- FT003

3. Measure the resistance between the sensor electrical connectors:
- FT002 pin 1 and FT002 pin 3
- FT003 pin 1 and FT003 pin 3

- Is the resistance between 16 and 160 Ohms?

-> Yes
REPAIR the relevant circuit. CLEAR DTC. TEST the system for normal operation.

-> No
INSTALL the relevant new fuel level sensor. CLEAR DTC. TEST the system for normal operation.

G92510t20: CHECK THE GROUND SUPPLY FROM THE INSTRUMENT CLUSTER
1. Disconnect the instrument cluster electrical connector IP010.
2. Measure the resistance at the instrument cluster between IP010 pin 9 and GROUND.

- Is the resistance less than 0.5 Ohm?

-> Yes
REPAIR the circuit between the instrument cluster IP010 pin 9, (B) and the fuel tank electrical connector CA005 pin 3, (B). CLEAR DTC. TEST the system for normal operation.

-> No
INSTALL a new instrument cluster. CLEAR DTC. TEST the system for normal operation.
