Additionally, being aware of common issues with the Power Door Memory Lock Relay can help avoid this code. Common problems with the Power Door Memory Lock Relay include a faulty relay, open or shorted harness, poor electrical connection, or a faulty Body Control Module (BCM).
Regularly checking and maintaining these components can help prevent the B1394 code.
What are the causes
Possible causes of code B1394 include:
- Faulty Power Door Memory Lock Relay
- The Power Door Memory Lock Relay harness is open or shorted
- Poor electrical connection in the Power Door Memory Lock Relay circuit
- Faulty Body Control Module (BCM)
- Other potential causes may also exist
To diagnose code B1394, technicians commonly use the following diagnostic tools:
- OBD-II scanner: This tool retrieves the trouble codes stored in the vehicle's computer system.
- Multimeter: This tool measures voltage, resistance, and continuity in electrical circuits.
- Wiring diagram: This tool helps identify the location and connections of the various components involved in the circuit.
- Visual inspection: This involves visually checking the wiring harness and connectors for any signs of damage or corrosion.
What Tools are Needed to diagnose
To diagnose the B1394 code, professional technicians need specific diagnostic tools. These tools include:
- Scan tool: A scan tool retrieves the trouble codes stored in the vehicle's onboard computer system. It allows technicians to access the Body Control Module (BCM) and gather information about the Power Door Memory Lock Relay.
- Multimeter: A multimeter is used for electrical troubleshooting. Technicians can measure voltage, resistance, and continuity in the Power Door Memory Lock Relay circuit. By testing the electrical connections and components, they can identify any faults or abnormalities.
- Wiring diagram: A wiring diagram provides a visual representation of the electrical circuit. It helps technicians trace the wiring and locate potential issues like open circuits, short circuits, or poor electrical connections.
With these tools, technicians can accurately diagnose the B1394 code and determine the necessary repairs or replacements to resolve the issue.
How to fix Step by Step
Step 1: Thoroughly inspect the vehicle's wiring harness and connectors.
Step 2: Look for any signs of damage, such as broken components or corroded connector pins.
Step 3: Identify any issues that are found during the inspection.
Step 4: Perform necessary repairs or replacements on the damaged components.
Step 5: Ensure all connections are secure and properly tightened.
Step 6: Follow the steps for diagnosing and repairing the B1394 code to ensure an accurate fix.
Step 7: Pay attention to detail and avoid common mistakes, such as overlooking damaged components or failing to check for poor electrical connections.
What are the Common Diagnosis Mistakes
Common diagnosis mistakes can make it difficult to accurately identify and solve the B1394 code. It's important to know about these mistakes to avoid wasting time and resources.
Here are some commonly missed causes of the B1394 code:
- Not checking the power door memory lock relay thoroughly: This part is important for the circuit to work properly. If the relay is faulty, it can trigger the B1394 code.
- Forgetting to inspect the body control module (BCM): The BCM keeps an eye on the power door memory lock relay. If the BCM itself is faulty, it can cause the B1394 code.
- Ignoring poor electrical connections: Weak electrical connections in the power door memory lock relay circuit can also trigger the B1394 code.
What is the Repair Cost
The repair cost for resolving the B1394 code can vary depending on factors such as location, make, model, and engine type.
Labor rates range from $75 to $150 per hour, with diagnosis typically taking around 1.0 hour.
Additional costs may apply for parts and further repairs.
