if the computer does not respond to an inpa command, then the problem is either the inpa hardware or the inpa software. the inpa hardware is not user-replaceable. therefore, if the inpa is not responding, the only option is to replace the inpa. the inpa software is user-replaceable. this can be done by following the basic steps listed in the following instructions. 1) install the existing inpa software. do not attempt to upgrade to a new version of inpa or ncs expert. if you try to do this, the inpa will not start. the reason is because the inpa software is not compatible with ncs expert 3.0.8. you must install the ediabas software for the cd/dvd-r (for example, i used ediabas: 2.6.2.3). 2) install the existing inpa software. if you try to do this, the inpa will not start. 3) reboot the car. 4) open the inpa software. 5) click on the start button.
properly assembled, an inpa cable must be able to transfer all the necessary information to and from your bmw vehicle. inpa has a 3 pin (pin 1,2,3) connection which is the same as the connection used by bmw, but in inpa its called k+dcan. this means the k means your car's obd system, and dcan is the standard protocol for this.
there are two types of inpa cable. one is the complete inpa cable which includes the necessary software (ncs expert and tool32). the other is the cable that is built to provide the data to the ncs expert software. this cable is called the k+dcan cable. the k+dcan cable is built to provide the necessary data to the ncs expert software but does not include the ncs expert software. it does include the necessary software (ncs expert and tool32). 84d34552a1
