INSPECT FUEL GAUGE SENDER UNIT SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
• Verify that the fuel gauge sender unit and rear body control module (RBCM) connectors are disconnected.
• Switch the ignition ON (engine off).
-
Note
-
• Another DTC may be stored by the PCM detecting an open circuit.
• Measure the voltage at the fuel gauge sender unit terminal E (wiring harness-side).
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between fuel gauge sender unit terminal E and rear body control module (RBCM) terminal 3I.
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to power supply.
Go to Step 11.

|
INSPECT FUEL GAUGE SENDER UNIT POWER SUPPLY CIRCUIT AND SIGNAL CIRCUIT FOR SHORT TO EACH OTHER
• Verify that the fuel gauge sender unit and rear body control module (RBCM) connectors are disconnected.
• Switch the ignition off.
• Inspect for continuity between fuel gauge sender unit terminals A and E (wiring harness-side).
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• Fuel gauge sender unit terminal A—Rear body control module (RBCM) terminal 3N
• Fuel gauge sender unit terminal E—Rear body control module (RBCM) terminal 3I
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to each other.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to each other.
Go to Step 11.
|
|
No
|
Go to the next step.
|
|
7
|
INSPECT FUEL GAUGE SENDER UNIT CIRCUIT FOR OPEN CIRCUIT
• Verify that the fuel gauge sender unit and rear body control module (RBCM) connectors are disconnected.
• Inspect for continuity between fuel gauge sender unit terminal C (wiring harness-side) and rear body control module (RBCM) terminal 3C (wiring harness-side).
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between fuel gauge sender unit terminal C and rear body control module (RBCM) terminal 3C.
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has an open circuit.
Go to Step 11.

|
|
No
|
Go to the next step.
|
|
9
|
INSPECT REAR BODY CONTROL MODULE (RBCM)
• Inspect the rear body control module (RBCM).
• Is there any malfunction?
|
Yes
|
Replace the rear body control module (RBCM), then go to Step 11.
|
|
No
|
Go to the next step.
|
|
