How to Fix B1316 Battery Saver Relay Coil Circuit Short to Ground
If you’re experiencing a B1316 Battery Saver Relay Coil Circuit Short to Ground error code, you’re not alone. This issue is common in many car models and can be frustrating to deal with. However, with the right tools and knowledge, you can fix this problem yourself and save money on costly repairs. In this article, we’ll provide you with step-by-step instructions on how to fix the B1316 error code.
What is the B1316 Error Code?
The B1316 error code is a diagnostic trouble code (DTC) that indicates a short circuit in the battery saver relay coil circuit. This circuit is responsible for controlling the power to the vehicle’s electrical system when the ignition is turned off. When this circuit is shorted to ground, it can cause a drain on the battery and prevent the vehicle from starting.
Before you begin fixing the B1316 error code, you’ll need to gather a few tools. These include:
- Socket set
- Wire strippers
- Electrical tape
- Soldering iron
- Heat shrink tubing
Now that you have your tools ready, let’s get started on fixing the B1316 error code.
Step 1: Disconnect the Battery
The first step in fixing the B1316 error code is to disconnect the battery. This will prevent any electrical shocks or damage to the vehicle’s electrical system. Use a socket set to remove the negative cable from the battery.
Step 2: Locate the Battery Saver Relay
Next, you’ll need to locate the battery saver relay. This is typically located in the fuse box under the hood of the vehicle. Refer to your vehicle’s owner’s manual for the exact location.
Step 3: Test the Relay
Using a multimeter, test the battery saver relay to determine if it’s functioning properly. Set the multimeter to the ohms setting and touch the probes to the relay’s terminals. If the multimeter reads zero ohms, the relay is functioning properly. If it reads infinite ohms, the relay is faulty and needs to be replaced.
Step 4: Check the Wiring
If the relay is functioning properly, the next step is to check the wiring. Use a multimeter to test the wiring for continuity. If there is no continuity, there may be a break in the wiring that needs to be repaired.
Step 5: Repair the Wiring
If there is a break in the wiring, use wire strippers to remove the damaged section of wire. Cut a new piece of wire to the same length and strip the ends. Use electrical tape to connect the new wire to the existing wiring.
Step 6: Solder the Connection
For a more secure connection, use a soldering iron to solder the new wire to the existing wiring. Cover the connection with heat shrink tubing to protect it from moisture and corrosion.
Step 7: Reconnect the Battery
Once you’ve repaired the wiring, reconnect the battery by attaching the negative cable.
Fixing the B1316 error code may seem daunting, but with the right tools and knowledge, it can be done. By following these step-by-step instructions, you can save money on costly repairs and get your vehicle back on the road.
