Diagnostic procedure
|
STEP |
INSPECTION |
ACTION |
|
|---|---|---|---|
|
1
|
• Switch the ignition to ON.
• Verify that the fuel gauge needle does not move after ignition switch is turned off, or the display does not indicate F even though the fuel tank is full.
• Is the fuel gauge normal?
|
Yes
|
Troubleshooting completed. (The system is normal.)
|
|
No
|
Go to the next step.
|
||
|
2
|
• Inspect the following fuel gauge needle indication when commands are sent to the instrument cluster using the M-MDS active command modes FUEL_GAUGE.
• Does the fuel gauge indicator move according to the command?
|
Yes
|
Go to Step 4.
|
|
No
|
Replace the instrument cluster.
|
||
|
3
|
• Inspect the instrument cluster connector connection.
• Is the instrument cluster connector connected securely?
|
Yes
|
Inspect for an open or short circuit in the instrument cluster power and ground circuit.
|
|
No
|
Connect the connector securely.
|
||
|
4
|
• Inspect the fuel gauge sender unit connector.
• Is the fuel gauge sender unit connector connected securely?
|
Yes
|
Go to the next step.
|
|
No
|
Connect the connector securely.
|
||
|
5
|
• Switch the ignition to off.
• Disconnect the instrument cluster and the fuel gauge sender unit connectors.
• Inspect for continuity between the instrument cluster wiring harness-side connector (24-pin) terminal 2M and ground.
• Is there continuity?
|
Yes
|
Repair or replace for a short to the ground circuit between the instrument cluster and the fuel gauge sender unit.
|
|
No
|
Go to the next step.
|
||
|
6
|
• Instrument cluster and fuel gauge sender unit connectors disconnected.
• Inspect for continuity between the instrument cluster and the fuel gauge sender unit.
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace for an open circuit between the instrument cluster and the fuel gauge sender unit.
