Can you register BMW battery with OBD2 Scanner?
A battery registration must be performed with a BMW OBD2 scanner (also known as a BMW diagnostic scanner or code reader). The BMW scanner tool is simply plugged into the OBD2 port underneath the dashboard of your vehicle which connects electronically to the engine control module (DME).
What does CSA stand for CSA?

CSA publishes standards in print and electronic form, and provides training and advisory services. CSA is composed of representatives from industry, government, and consumer groups.
What do the letters mean on wire?
The information printed on the sides of wire indicates its THHN/THWN, material, max voltage rating and gauge. THHN/THWN. THHN/THWN letters represent the most common types of electrical wires used in residential applications.
How you can recognize a CSA approved power cable?
Use CSA approved parts in the high voltage/ high power section of the wiring โข CSA approved parts will be marked with a symbol that certifies it as an approved parted.
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.
Where is the IBS sensor?
Intelligent Battery Sensor (IBS) The IBS is mounted directly onto the battery and fits exactly into the niche around the negative terminal.
