Modules manufactured after mid 2015 (version 7.1 and later) will blink a distinctive light pattern when plugged in (or waking from sleep).
- First you'll see all of the LEDs cycle in sequence as it runs it's internal diagnostics and transitions to operational status.
- You'll see LED #4 (far left LED when plugged into the OBD2 port) BLINK the major Version number.
- You'll see LED #3 (2nd from the left LED) BLINK the minor Version number.
Version 8.1 would blink LED #4 EIGHT (8) times with a small pause and then LED #3 ONE (1) time for 8 point 1.

NOTE: You will NOT see this pattern on early modules (Version 7 and earlier) and if this is the case, you should send the module to us for updating.
