OBD2 Code: B1325
Description: Device Power Circuit Voltage
Common Diagnostic Steps:
- Check the battery voltage and ensure it is fully charged. A weak or dead battery can cause this code.
- Inspect all related fuses and replace any that are blown.
- Examine the wiring harness for signs of damage, such as fraying, corrosion, or disconnection. Repair or replace as necessary.
- Test the power circuit for continuity using a multimeter to ensure there are no open circuits.
- Verify that all ground connections are clean and secure. Poor grounding can lead to voltage issues.
- If equipped, check the alternator output to ensure it is charging properly.
- Use a scan tool to clear the code and perform a test drive to see if the code returns. If it does, further diagnosis may be needed on specific components in the power circuit system.
