I'm having a problem with my V2 reading 0-5V voltage. I used my V1 with external voltage devices before I upgraded with no problems, but this is the first time I've tried it with the V2. I hooked up a UEGO 1000 wideband and got no info from it. JoeCar helped me with a few troubleshooting techniques (Thanks again for the help!!) After checking wiring and using a multi-meter to verify 0-5VDC from the O2, I hooked a AA battery to the analog inputs. No voltage!
I hooked the scan tool up to the OBDII port and placed it into test mode. No 0-5V response, 12 V switched inputs work fine. I don't have a thermocoupler to test those 2 inputs.
I sent my V2 in after the first time I used it because after the first use it would not communicate with a vehicle again. (sent it in around Sept. 07) Had no problems with it after that until now.
Any more advice would be very helpful.
