7. Insert the Power Programmer into the diagnostic port by aligning the center index pin properly, while rotating the locking collar so
that the entire device lowers and locks into position. Usually you will hear a slight “click” as the locking ring seats fully on the
port’s housing.
8. Turn the ignition switch to the ON position but do not activate the starter (“Check Engine” lamp must light up). Do this through the
open driver’s window. Do not open the door.
9. Assure that ALL electrical loads are OFF (radio, climate control, courtesy lamps, etc) and that devices capable of turning them-
selves on (e.g. cell phone) are disabled temporarily. Do not open any of the vehicle’s doors.
10. The Power Programmer’s “STATUS” LED should now be steadily illuminated green.
11. Press the “UPGRADE” button and within 3 seconds, the “STATUS” LED will begin to pulsate green indicating the transfer of
programming data between the vehicle’s ECU and the Power Programmer.
12. Sit back and watch, but do not touch anything inside the vehicle or the Power Programmer itself under any circumstances.
Do not open the vehicle doors as this can disturb programming.
13. In 1 to 7 minutes, the red “ACTIVE” LED will turn on while the green “STATUS” LED continues to pulsate indicating that the Power
Programmer is entering the reprogramming phase.
14. In another 1 to 4 minutes, the red “ACTIVE” LED will turn off, while the green “STATUS” LED will continue to pulsate; this is the final
CHECK phase of the reprogramming procedure.
15. Finally, in about 1 to 4 minutes, the green “STATUS” LED will stop pulsating and illuminate steadily. This is your indication that the
programming upgrade has been verified. (If you see a solid green “STATUS” LED AND a solid red “ACTIVE” LED, this indicates that
a RESTORE TO STOCK procedure was successfully completed.)
16. You may now open the vehicle door and turn the ignition completely off. Wait at least 30 seconds, but do not remove or disconnect
the Power Programmer at this time.
17. If the vehicle is a M3 95 thru 99 with automatic transmission, at this time you MUST reconnect the Transmission Control Unit
that was previously disconnected (see appendix A), before proceeding.
18. If the vehicle is a 528i or 540i 99 on, then reinstall fuses 17 and 31.
19. If the vehicle is a 740i/il 99 on, then reinstall fuse 17.
NOTE: At this point, it would help to have an assistant to turn the key or watch the Power Programmer. During the next two steps,
things happen both subtly and quickly!
20. With the Power Programmer still connected to the vehicle, turn the ignition switch to the ON position but do not activate the starter
(Check Engine lamp must light up).
21. Watch (but do not touch) the Power Programmer, the green “STATUS” LED will begin to pulsate almost immediately indicating the
transfer of some final information to the vehicle’s ECU. This phase lasts only about 10-15 seconds before the green “STATUS” LED
illuminates steadily. (In other words, if you are slow getting from the ignition switch around to look at the Power Programmer, you
may miss this short-lived event.) Once the green “STATUS” LED is illuminated steadily, you may proceed.
22. You may now turn the ignition completely off. Then, wait at least 30 seconds.
23. Remove the Power Programmer from the diagnostic port and recap the port.
24. Turn off and remove the battery charger.
25. Close and secure the hood.
