The Passlock system, a vital component of your vehicle’s security features, prevents theft by guaranteeing that your car can only be started with the correct key. This advanced system provides several benefits, including bolstered security and reduced theft risk. In terms of security overview, the Passlock system consists of a security hall effect sensor, Body Control Module (BCM), and a learned voltage value. Here’s a breakdown of how it works:
| Component | Function | Benefit |
|---|---|---|
| Security Hall Effect Sensor | Detects the correct key | Guarantees only authorized access |
| Body Control Module (BCM) | Provides power and reference voltage | Facilitates secure communication |
| Learned Voltage Value | Compares to sensor voltage | Prevents unauthorized startups |
| Passlock System | Prevents theft and unauthorized access | Boosts overall vehicle security |
Possible Causes of B2960 Code
When your vehicle’s Passlock system malfunctions, it can trigger the B2960 code, indicating that the security system sensor data is incorrect but valid.
You’ll need to investigate possible causes, including sensor failure, which can occur due to a faulty security system sensor or its harness being open or shorted. Wiring issues, such as poor electrical connections in the security system sensor circuit, can also trigger the fault code.
Additionally, a faulty Body Control Module (BCM) may be the culprit. It’s essential to identify and address the root cause to resolve the issue.
How to Fix the B2960 Code
To fix the B2960 code, start by reviewing the possible causes listed above and visually inspecting the related wiring harness and connectors.
Check for damaged components and look for broken, bent, pushed out, or corroded connector pins. Use car troubleshooting techniques and diagnostic tools to identify the root cause of the issue.
If you’re not comfortable with DIY car repairs, consider consulting a professional mechanic for assistance. Remember to clear the code with a scan tool once the repairs are complete to guarantee the issue is fully resolved.
Symptoms of the B2960 Code
Your vehicle’s Check Engine Light or Service Engine Soon Warning Light comes on, indicating an issue with the security system.
This is a clear sign of car trouble, and you’ll need diagnostic tools to identify the root cause.
A clear sign of car trouble, requiring diagnostic tools to uncover the root cause of the issue.
When the B2960 code is triggered, you may experience difficulty starting the engine or notice the security light staying on.
These symptoms can be frustrating, but don’t ignore them – they’re warning signs of a problem that needs attention.
Visual Inspection and Troubleshooting
