B1325 Code Symptoms, Causes, and Fixes
Are you currently dealing with a B1325 diagnostic trouble code and unsure what it means or how to resolve it? Look no further. In this blog post, we will explore the implications of this standard OBD2 trouble code, the reasons behind its occurrence, and the steps to fix it.
What does B1325 mean?
The B1325 trouble code is a diagnostic trouble code. OBD-II scanners can identify it. Some examples of these scanners are Actron, Ancel, Autel, Creator, Foxwell, Innova, Launch, and Konnwei.
Chevrolet vehicles are primarily associated with it. The code appears when the car’s system detects low or high voltage on the power circuit for the control module. This causes the Check Engine Light to illuminate.
Possible Symptoms of Code B1325
The most noticeable symptom of the code B1325 is the illuminated Check Engine Light. However, it could also lead to the failure of all body control functions or BCM and possibly deactivate all instruments in the instrument cluster.
B1325 Possible Causes:
The B1325 trouble code is often caused by a powertrain control module issue. This can include a faulty module, a damaged power harness, or a weak electrical connection.
Potential causes of the B1325 trouble code may involve the following:
- Problems in the charging system can prevent the battery from fully charging. This can be due to a dead battery or damaged battery terminals.
- Malfunctioning or declining alternator parts such as the bridge rectifier or voltage regulator, provided the alternator comes with an inbuilt regulator
- Impaired, scorched, short-circuited, disconnected, rusted wiring harness, corroded connector pins, and electrical connectors within the charging system.
- Insufficient engine or chassis ground links, or intermittent loss of ground connection.
- Improper installation of unauthorized aftermarket electrical accessories like unapproved audio equipment and supplementary driving lights.
- Previous but insufficient electrical repairs and/or alterations.
- I am unplugging the battery for any purpose.
- Control module(s) rarely fail, so you should investigate any fault before condemning any control module outright.
Diagnostic procedures
To diagnose a B1325, do the following:
- Search for error codes in the Engine Control Module and examine the freeze frame data for malfunction.
- Conduct a visual examination of the Control Module Power cable for any potential harm.
- Measure the voltage on the power circuit of the control module.
- Evaluate the resistance on the power circuit of the control module.
Frequent Errors:
When diagnosing a B1325 code, technicians should focus on inspecting all wiring and connectors for damage. They should also check the voltage and resistance on the power circuit for the power control module or body control module.
How serious is it?
The B1325 code is quite serious and needs immediate attention. If not resolved promptly, it can lead to significant vehicle issues.
How to fix the B1325 code?
To resolve the B1325 code issue:
- Repair or replace any damaged wiring.
- Inspect the power circuit’s voltage for the control module.
- Examine the power circuit’s resistance for the control module.
- If the issue lies with a control module, replace it.
DIY Solutions: How to Tackle the B1325 Code at Home
1. System Reset:
- Fix: Perform a system reset.
- How-To: Turn off your vehicle and disconnect the battery for a few minutes, then reconnect. This can sometimes clear temporary glitches causing the b1325 code.
2. Battery Check:
- Fix: Ensure a healthy battery.
- How-To: Regularly check your vehicle’s battery for signs of weakness or corrosion. A weak battery can trigger the B1325 code.
Conclusion:
The b1325 code warns of potential power circuit voltage issues with the control module. Remember, this is a serious code and warrants immediate repair. If you need help with how to proceed, seek assistance from a professional technician. You can resolve this issue with prompt and proper attention, and you can get back on the road in no time.
