What is B1392 Power Door Memory Lock Relay Circuit Failure?
B1392 is a diagnostic trouble code (DTC) that indicates a problem with the power door lock system. Specifically, it refers to a failure in the power door memory lock relay circuit. This circuit is responsible for controlling the power door locks and storing the memory of their position. When this circuit fails, it can cause issues with the power door locks, such as them not working at all or only working intermittently.
Step-by-Step Guide to Fixing B1392 Power Door Memory Lock Relay Circuit Failure
Step 1: Check the Fuses
The first thing you should do when experiencing issues with your power door locks is to check the fuses. The power door lock system is typically controlled by a fuse, and if this fuse is blown, it can cause the system to fail. Check your car’s owner’s manual to locate the fuse box and find the fuse that controls the power door locks. If the fuse is blown, replace it with a new one and see if that fixes the issue.
Step 2: Check the Wiring
If the fuses are not the issue, the next step is to check the wiring. Look for any signs of damage or wear on the wiring that connects to the power door lock system. If you find any damage, you may need to replace the wiring or have it repaired by a professional.
Step 3: Check the Power Door Lock Relay
If the fuses and wiring are not the issue, the problem may be with the power door lock relay. This relay is responsible for controlling the power door locks, and if it fails, it can cause issues with the system. To check the relay, locate it in your car’s owner’s manual and test it with a multimeter. If the relay is faulty, you will need to replace it with a new one.
Step 4: Check the Power Door Lock Actuator
If the power door lock relay is not the issue, the problem may be with the power door lock actuator. This is the component that physically moves the lock mechanism to lock and unlock the doors. If the actuator is faulty, it can cause issues with the power door locks. To check the actuator, remove the door panel and test it with a multimeter. If the actuator is faulty, you will need to replace it with a new one.
