Yes, a loose battery cable can cause the ABS battery light to illuminate, as it can disrupt the electrical supply to various systems in the vehicle. This loose connection may also cause the radio to turn off and the speedometer needle to flutter due to inconsistent power delivery. It’s important to ensure that all battery connections are secure to avoid these electrical issues. If the problems persist after tightening the cable, further diagnosis may be needed.
