How Do I Know If My BCM Is Faulty?

A faulty Body Control Module (BCM) can cause a variety of electrical issues in your vehicle. Here are some common signs and symptoms that indicate your BCM might be malfunctioning. Yes UpFix repairs BCMs!

Common Symptoms of a Faulty BCM:

  1. Electrical Component Failures:

    • Intermittent Operation: Electrical components such as headlights, tail lights, windshield wipers, and power windows work intermittently or fail completely.
    • Non-Operational Components: Certain components like power seats, mirrors, or door locks do not operate at all.
  2. Starting Problems:

    • Difficulty Starting: The vehicle has difficulty starting, often related to the security system or keyless entry.
    • No-Start Condition: The vehicle fails to start altogether, even though the battery and starter are in good condition.
  3. Battery Issues:

    • Battery Drain: The battery drains quickly or is frequently dead due to electrical components being powered when they shouldn’t be.
  4. Warning Lights:

    • Erratic Warning Lights: Warning lights on the dashboard illuminate without any actual issue or fail to illuminate when there is a problem.
  5. Erratic Behavior:

    • Random Activation: Electrical components activate or deactivate unexpectedly, such as lights flickering, the HVAC system turning on by itself, or windows moving on their own.
  6. Blown Fuses:

    • Frequent Blown Fuses: The vehicle experiences frequent blown fuses, indicating an underlying electrical issue that may be related to the BCM.

Diagnosing a Faulty BCM:

  1. Visual Inspection:

    • Check for Damage: Inspect the BCM for any visible signs of damage, such as burnt components, corrosion, or loose connections.
    • Check Connectors: Ensure all connectors to the BCM are secure and free of corrosion.
  2. OBD-II Scanner:

    • Read Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to read any stored DTCs. Codes related to various body systems can indicate BCM issues.
  3. Battery and Charging System:

    • Check Battery Voltage: Use a multimeter to check the battery voltage. A fully charged battery should read around 12.6 volts or higher. Low voltage can cause BCM issues.
    • Check Alternator Output: Ensure the alternator is charging the battery properly, reading between 13.7 to 14.7 volts when the engine is running.
  4. Component Testing:

    • Test Affected Components: Test the components that are malfunctioning to rule out other potential causes such as bad switches, motors, or wiring.
  5. Professional Diagnosis:

    • Seek Professional Help: If the issue persists or you’re unable to diagnose it yourself, consider seeking professional diagnostic services. Technicians have the tools and expertise to accurately diagnose BCM issues.
