MS3 Not Functioning

Post by alexofnazareth »

Hey guys. I unplugged the DB37 Connector while the power was still on to my fuse block. I moved the J1 jumper to switch my IGN settings.

Now none of the LEDs are illuminated and it won't connect to tunerstudio. Is there any way to check what has failed?


Thanks.

I'm getting 12v across pins 28 and 19. So there's power going to it.

Also the quicker someone can help me confirm if its a lost cause, the quicker I can put in an order for another one.

Remove the MS3 daughter-board and do all the voltage checks at the mainboard 40-pin connector, per the assembly instructions for the V3.0
