    I am not sure what you are asking. Can you explain what a trigger point is? Something with the crank trigger maybe?

    Its a GM 6+1 signal.

    ODB2 uses a VR signal to the PCM.
    ODB1 sends the VR signal to the ICM. The ICM conditions the signal and transforms it into a hall signal to the PCM.
