Fuel Door Actuator Circuit Open
Code B2364 indicates that the Body Control Module (BCM) or the fuel door control module has detected an open circuit in the fuel door actuator or its wiring. This prevents the module from locking or unlocking the fuel door, whether via the interior button, remote key fob, or automatically when the vehicle is unlocked.
1. Commonly Affected Makes
2. Most Common Causes
- Faulty fuel door actuator (open coil internally)
- Damaged, cut, or disconnected wiring between the BCM and the actuator
- Loose, corroded, or pushed-back terminals at the actuator or BCM connector
- Blown fuse in the actuator power circuit
- Internal BCM failure in the output driver
3. Symptoms You Will Notice
- Fuel door will not lock or unlock
- Fuel door remains stuck in one position
4. Step-by-Step Diagnosis
Check the fuel door actuator fuse and replace if blown.
Inspect the wiring and connectors between the BCM and actuator for damage, corrosion, or loose terminals.
Test the actuator by applying power and ground directly; if it doesn't operate, replace the actuator.
If wiring and actuator are good, suspect a BCM fault and perform further BCM diagnostics.
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is safe to drive. The fuel door may not lock, but the vehicle remains drivable.
How much does it cost to fix?▼
Typically $150 to $400, depending on whether the actuator or BCM needs replacement and labor rates.
