Common Signs of a Failing BCM

If your Saturn Vue is experiencing these issues, a faulty BCM is the likely culprit:

• ✔ Erratic or non-functional power windows, door locks, or interior lights.
• ✔ The security or anti-theft light stays on, causing a no-start condition.
• ✔ Dashboard warning lights flicker or illuminate for no reason.
• ✔ Horn, wipers, or other accessories operate intermittently on their own.
• ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140.

A Straightforward Guide to Installation

This module is designed for a direct replacement. For the handy DIYer, this is a manageable weekend project.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. Locate the BCM: In the 2008-2010 Saturn Vue, the Body Control Module is located behind the center dash console. Access may require removing some trim panels.
3. Perform the Swap: Carefully release the locking tabs on the electrical connectors and unplug them. Unbolt the old BCM, remove it, and mount the new module in its place.
4. Reconnect Everything: Securely plug in all electrical connectors to the new BCM. You should hear a click as they lock in place. Reconnect the negative battery terminal.

Important Post-Installation Information

While our programming handles the majority of the setup, some vehicles may require additional steps to sync with other onboard systems:

• Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
• No Core Charge: You are not required to return your old module. There is no core charge or deposit associated with this purchase.

Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any part of the process.
