To reset the engine control module (ECM) on a Chevrolet Silverado without a scan tool or mobile app, you can try a simple method. Start by popping the hood of your truck and locating the battery. Loosen the nut on the negative battery cable and disconnect it from the battery. Then, go inside your truck and turn the headlight switch to the ON position to drain any remaining power from the ECM. Wait for at least 10 minutes before switching the headlight switch off. Reconnect the negative cable to the battery and tighten the nut. Your ECM should be reset using this manual method.
Why is the ECM mentioned as the top answer when the question is actually about the BCM?
In 2007, there was a problem with the BCM in the Chevrolet Silverado's new body style. There is no power, lights, or electrical functions, despite a charged battery. The scan tool does not detect anything. I am considering resetting the BCM by disconnecting the black cable for 10 minutes. Will this reset solve the issue and make my truck operational again? Thank you.
I'm dealing with a similar issue that arose at a gas station where I had to pay for a tow back home. Has anyone discovered a solution for this problem?
My pickup truck won't start, it won't even make a sound when I try to turn it on.
