Looking down at the fuse box standing in front of the car, fuses #11 and #12 are grouped together in a yellow clip located in the lower left hand corner of the fuse box. It is located under the hood in the main fuse box. It's labeled in the shop manual as dedicated fuse #11. The same fuse powers the key illumination ring, the lights in the rear view mirror, the foot light under the dash, and also provides battery backup power to the ECU. If pin 16 does not show power (it should have 12v at all times when measured against pin 5), the fuse powering this pin may be blown. You can get information on ECU connector pin locations from the ECUWiringInformation page.
Pin 16 can be connected to ECU pin 80 (connector B-56, Red-Blue) if needed. In that case, you'll also what to check to make sure the select COM port isn't actually a built-in modem or IRDA port or something like that.ĭiagnostic line to ECU (connector B-55, pin 56, yellow)ĭata line to ECU (connector B-55, pin 62, pink)

V2 ONLY: If your laptop has a built-in DB9 serial port (i.e., you're not using a USB/DB9 adapter), then the COM port you'll want to use will be something like the plain Communications Port (COM1) port listed in the diagram above.

If you don't even see your USB/DB9 adapter listed in device manager as illustrated above, then you'll need to start debugging why your adapter driver isn't properly installing itself. If that's still not working, then at least you know you have the correct COM port selected and there's no need to go swapping around with that. Once you know that, you enter that COM port into ECMLink (in the V2 app, that's under Edit→Options→Config) and try again. That should tell you for sure which COM port you should be using in ECMLink. Now, expand the Ports (COM & LPT) tree node and you should see something like this image: Right click on My Computer, select Properties, go to the Hardware tab and click on Device Manager. In general, you should be able to pull up the Windows Device Manager for this. First you have to figure out for sure which COM port to use.
