What is IBS sensor?
Intelligent Battery Sensor (IBS) The shunt-type IBS continuously analyzes the status of conventional 12-Volt lead acid batteries and provides information on such key parameters as the state-of-charge, state-of-function (power ability) and state-of-health (aging) of the battery.
How do you test an IBS sensor?
Once the scanner is plugged in, turn the ignition on, but don’t start the engine. Scroll through the menus on the scanner, locate the DME option, and scan for fault codes. If you see “299B DME Intelligent Battery Sensor” or “002E8D DME: Intelligent Battery Sensor, signal transmission”, there is a problem with the IBS.
