A Technician’s Notebook: The Intermittent Fleet Van
I remember a local delivery company brought in one of their Savana 3500 work vans. The complaint was a classic “ghost in the machine” scenario. The driver reported that sometimes the turn signals wouldn’t work, the radio would cut out, and occasionally the security light would stay on, preventing the van from starting. They had already replaced the battery and checked the main grounds. After hooking up my scan tool, I saw a slew of U-codes (communication errors) pointing to the BCM. On these workhorses, years of vibration and thermal cycling can cause microscopic cracks in the BCM’s circuit board. We performed our cloning service onto a replacement module, and the van was back in service the next day, running without a single electrical hiccup. It’s a common failure I’ve seen solve dozens of otherwise baffling cases.
Is Your Van Showing These Symptoms?
- ✔ Unresponsive or malfunctioning power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays illuminated, causing a no-start condition.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ Intermittent operation of the radio, climate controls, or horn.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0100, U0140, or other U-series codes.
- ✔ False warnings on the driver information center (e.g., “Service StabiliTrak”).
A Straightforward Guide to BCM Installation
- ✔ Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most Savana and Express vans, the BCM is located in the center dash area, often accessible by removing lower dash panels. Refer to a service manual for the exact location on your specific model.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair was successful.
- ✔ Perform Relearns (If Needed): In some cases, you may need a professional scan tool to perform a ‘Brake Pedal Position Relearn’ or ‘Setup SDM Primary Key in BCM’ if related warning lights appear.
