1. Disconnect the connector C310 beneath the rear passenger seat. Refer to Rear Seat Cushion Replacement in Seats for access.
2. Connect a fused jumper from the YEL/RED wire of connector C310 cavity 1, and a known good ground.
3. Turn the ignition switch to the ON position.

Does the fuel gauge indicate F?

Go to Step 3

Go to Step 10

3 | Important: The measured resistance should be between 0 - 130 ohms depending on the amount of fuel in the fuel tank. Test for continuity between the YEL/RED wire of connector C310 cavity 1, and a known good ground. Did you measure the resistance in the YEL/RED wire? | 0-130ohms | Go to Step 12 | Go to Step 4

4

1. Disconnect connector C300 located beneath the rear passenger seat. Refer to Rear Seat Cushion Replacement in Seats for access.

Important: The measured resistance should be between 0 - 130 ohms depending on the amount of fuel in the fuel tank.

2. Test for continuity between connector C310 cavity 1, and connector C300 cavity 2.

Did you gauge the amount of resistance in the BLK wire?

0-130ohms

Go to Step 9

Go to Step 6

5 | With Connector C300 still disconnected. Test for continuity between connector C300 cavity 2 and ground. Was there continuity in the BLK wire? | -- | Go to Step 3 | Go to Step 9
6 | Inspect the fuel harness wires and the connectors for damage. Refer to Fuel Sender Assembly Replacement in Engine Controls for access. Is any damage present? | -- | Go to Step 7 | Go to Step 8
7 | Repair or replace any damaged wires or any damaged connectors. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Instrument Cluster System Check | --
8 | Replace the fuel level sensor. Refer to Fuel Level Sensor Replacement in Engine Controls. Is the repair complete? | -- | Go to Instrument Cluster System Check | --
9 | Repair the BLK wire between the fuel sender cavity 2 and ground. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Instrument Cluster System Check | --

10

1. Disconnect the IP cluster assembly connector C3. Refer to Instrument Cluster Replacement for access.
2. Disconnect the powertrain control module connector C2.
3. Connect a J 39200 from the connector C3 cavity 9 of the instrument panel cluster to cavity 1 of connector C310 .
4. Measure the resistance.

Is the measured resistance less than the specified value?

2 ohms

Go to Step 11

Go to Step 13

11 | Inspect the printed circuit of the instrument panel cluster for damage or for loose connections. Is the circuit OK? | -- | Go to Step 12 | Go to Step 14
12 | Replace the fuel gauge. Refer to Fuel Gage Replacement . Is the repair complete? | -- | Go to Instrument Cluster System Check | --
13 | Repair the YEL/RED wire between the instrument panel cluster assembly and C310. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Instrument Cluster System Check | --
14 | Repair the instrument cluster printed circuit. Refer to Printed Instrument Cluster Circuit Replacement . Is the repair complete? | -- | Go to Instrument Cluster System Check | --
