Smohsin Posted August 13, 2021 Report Share Posted August 13, 2021 The car is not starting even i have replaced the cam sensor with hall type from a bmw n42 somehow i managed to check in runtime values i am getting cam signal but i am not getting crank signal attaching the snapshot i checked the wiring twice and what i see crank sensor is not getting 5 volts from the ecu which is ecu pin 16 in my application what can be the cause ?as it should be a direct 5V output from ecu when i turn ignition to on.. i have 5 volts on cam sensor even on throttle sensor I unlocked the ecu upgraded the firmware but no luck yet Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted August 13, 2021 Report Share Posted August 13, 2021 Hall effect Crank sensor should have 12v on BMW not 5v. Also enable the pull-up on the crank. Quote Link to comment Share on other sites More sharing options...

In ecu setup it has selected to relucter type i have attached snapshot as well plus i have tried with 12 volt as well but triger 1 stays off in runtime values i am using base map whatever settings comes by default it is as it is..

Adamw Posted August 13, 2021 Report Share Posted August 13, 2021 M52 has a hall effect Crank sensor and needs to have power wired to it as Clint suggests above and as I have said previously in your other thread. It does not get its power from pin 16, that is the trigger 1signal. Trigger settings for the M52 are in the help file in the engine specific information folder.

Adamw Posted August 14, 2021 Report Share Posted August 14, 2021 You need to set the trigger mode to M52 as mentioned above. Quote Link to comment Share on other sites More sharing options...
