If you encounter the B1560 code, it’s time to take action. This trouble code suggests that the door lock cylinder circuit is open, indicating a potential issue with the electrical connections in your vehicle’s locking mechanism. Begin by inspecting the wiring and connectors for any signs of damage or corrosion. A simple visual check can reveal loose or frayed wires that may be disrupting the circuit.
Next, test the door lock cylinder itself. Use a multimeter to check for continuity in the circuit. This step helps pinpoint whether the issue lies with the cylinder or somewhere in the wiring harness. If the cylinder shows no continuity, replacement may be necessary. Conversely, if the wiring is intact, further investigation into the vehicle’s body control module (BCM) is warranted.
While addressing the B1560 code, ensure to clear any fault codes from the system after repairs. This will help you verify that the issue has been resolved successfully. Monitor the system, and if the code returns, consider consulting a professional for deeper diagnostic procedures. Maintaining a functional door locking mechanism enhances both the safety and convenience of your vehicle.

Document your findings and any actions taken, as this information can be helpful for future reference or when consulting with a mechanic.
How to Check Door Lock Cylinder Wiring
Begin by disconnecting the battery to prevent any electrical shorts or shocks. Next, locate the wiring harness connected to the door lock cylinder. Inspect the wiring for any visible damage such as frayed insulation, corrosion, or loose connections.
Using a multimeter, check for continuity by setting the device to the resistance measurement mode. Touch one probe to the wiring harness terminal and the other to the corresponding terminal of the door lock cylinder. A reading close to zero indicates proper connectivity. If the multimeter shows infinite resistance, there’s a break in the circuit.
Next, examine the ground connection. A poor ground can cause various electrical issues. Ensure the ground wire is securely attached and free of corrosion. You can also test the ground with the multimeter by checking the resistance between the ground terminal and the vehicle’s chassis; it should be minimal.
If wiring and connections appear intact, activate the lock switch while monitoring the voltage at the door lock cylinder terminals. You should detect battery voltage when the switch is engaged. If voltage is absent, there may be an issue with the switch or the wiring leading to it.
Finally, trace the wiring back through the door to the body and inspect all connectors along the way. Make sure they are clean, secure, and free from moisture. Address any anomalies promptly to ensure the door lock operates correctly.
Testing the Functionality of the Door Lock Actuator
Begin by ensuring the vehicle’s battery is fully charged. A weak battery can affect actuator performance. Use a multimeter to verify voltage at the actuator connector. It should read close to the battery voltage when the door lock switch is activated.
Actuator Operation Check
Lower the window or open the door for access. With the door open, press the lock/unlock button multiple times. Listen for the actuator’s engagement sounds. A clicking noise indicates a mechanical issue, while silence suggests electrical problems or a faulty actuator.
Voltage and Ground Testing
If the actuator is silent, test for voltage at the actuator connector using the multimeter. If voltage is present but the actuator doesn’t operate, replace the actuator. If there’s no voltage, inspect the wiring harness for breaks or loose connections. Check the door lock switch as well; it may need replacement if defective.
Reassemble the door and test the lock function. A working actuator will respond promptly to commands from the key fob or door controls. Document any issues encountered during testing for reference in future repairs.
Identification of Potential Grounding Issues
Check the grounding connection first. A loose or corroded ground wire can lead to erratic behavior in the locking system. Secure all connections to ensure proper functioning.
Next, measure the grounding resistance using a multimeter. A reading above 5 ohms may indicate a problem. If the resistance is high, inspect the ground electrodes and connections for corrosion or physical damage.
Ground loops may also create issues. Ensure that all components share a common ground point. Disparate grounding points can result in voltage differences, affecting system performance.
Additionally, verify the integrity of the wiring. Damaged or frayed wires can interrupt the grounding path, leading to faults in the door lock circuitry. Replace any compromised wiring promptly.
Consider environmental factors affecting grounding. Moisture, dirt, or rust can impact ground connections. Regular maintenance can mitigate these effects, ensuring reliable door lock operation.
| Issue | Possible Solution |
|---|---|
| Poor ground connection | Inspect and tighten connections |
| High grounding resistance | Check and replace corroded components |
| Ground loops present | Establish a single grounding point |
| Damaged wiring | Replace frayed or damaged wires |
| Environmental impact | Regularly clean and maintain connections |
Assess these factors to ensure the reliable operation of your door lock system and prevent issues related to the B1560 code.
Checking for Short Circuits in the Door Lock Cylinder Circuit
Begin by inspecting the wiring connections related to the door lock cylinder. Look for any visible signs of wear, fraying, or corrosion that could indicate a short circuit. Pay close attention to areas where wires may rub against metal components or connectors.
Next, use a multimeter to test for continuity. Disconnect the battery and isolate the cylinder lock circuit. Set your multimeter to the continuity setting and probe the circuit wires. A continuous beep indicates a short circuit; no sound suggests the circuit is intact.
Inspect connectors and terminals for moisture or debris. Clean them gently using electrical contact cleaner, as contaminants can create false readings and unexpected behavior in the circuit.
| Step | Action |
|---|---|
| 1 | Check wiring for signs of wear or damage |
| 2 | Disconnect battery and isolate the circuit |
| 3 | Test for continuity with a multimeter |
| 4 | Inspect and clean connectors and terminals |
If a short circuit is detected, carefully trace the wiring to locate the exact point of failure. You may need to repair or replace damaged sections of the wiring to restore proper functionality. After making repairs, retest the circuit for continuity to ensure all issues have been resolved.
Testing the Door Lock Switch Integrity
Use a multimeter to check the door lock switch’s integrity. Start by disconnecting the wiring harness from the switch. Set the multimeter to the continuity setting. Connect one lead to the switch terminal and the other to the ground.
If the switch operates correctly, the multimeter should show continuity when the switch is activated. If there’s no reading, the switch is faulty and requires replacement. Test both the locking and unlocking positions to ensure full functionality.
Next, examine the wiring for any visible damage or corrosion. Any compromised wires can disrupt the circuit, leading to an open circuit error. Repair or replace damaged wiring as needed.
Additionally, check the ground connection. A poor ground can also trigger fault codes. Ensure the ground is clean and securely attached to the body of the vehicle.
After completing these tests, reconnect the switch and retest the system to confirm the issue has been resolved. If problems persist, further diagnosis of the vehicle’s locking system may be required.
