I wish to outfit a fleet of Subaru powered off-road vehicles with CDL3s. From what I have read, the OBD2 interface is the best option for obtaining Subaru ECU sensor values. In reading the installation process as it pertains to the CDL3/OBD2 configuration, the process requires the pressing of RED switch (part of the track kit harness) to complete the installation/programming/configuration.
Question:
Is the pressing of the RED button required each time the CDL3 is powered up, or is this a one time process on initial installation?
If the Subaru ECU is swapped for another Subaru ECU from a like vehicle, is the RED button process required upon swap, or is this a one time process?
Thanks,
