2013年8月14日 · According to WDS, IBS is in all the diagrams for all E90 model years. The brown cable and exposed terminal clamp in your picture strongly suggest to me someone didn't know what to do with it and/or broke it and simply replaced the cable without it.

2016年9月2日 · There is no straightforward DIY mechanic way of testing it other then reading the enhanced powertrain codes to see if it is in fault. I believe the fault is thrown when the DME doesn't receive a message from it for a certain period of time, which pretty much means when you get the fault it can only be the sensor or the wiring.

2018年1月9日 · If IBS itself has gone bad which is located directly on the negative terminal, then the car may not start. Often, taking that blue connector out temporarily, may start the car since that stops communication between ECU and IBS.

2015年10月24日 · Just unplugging the IBS cable from the negative cable will disable the IBS communication to the DME . The only thing with it bypassed there will be no battery information monitoring or charging information data sent to the DME .

2014年7月23日 · IBS emergency mode boosts the idle speed in order to sufficiently charge the battery. Direct diagnosis of the IBS is not possible, it can only be diagnosed through the DME. The self-diagnosis function checks the voltage, current, temperature, terminal 15 wake up signal as well as system errors in the IBS.

E90 Voltage Supply & Bus Systems The IBS is able to withstand thermal loads up to 105°C, the chemical effects of the bat-tery acid. The components of the IBS are shown below: *Manganin - Is a copper alloy resistor with a low resistance value, that is able to maintain an extremely constant temperature regardless of current flow.

2022年6月12日 · Below are some useful documents on purpose and detailed architecture of the IBS system. Some are linked from E6x group, but ours should be similar. BMW e90 Voltage Supply & Bus Systems
