View Full Version : V2 not reading AD signal

I just received my V2 a couple of weeks ago along with LM1 wideband. After spending hours trying to trouble shoot with AD calibrating and measuring output/input with a volt meter I finally checked the V2 and sure enough its not registering the raw data coming from the Wideband.
Is there a fix for this?

Ponch,
Did you connect as follows:
ADn+ = positive side of voltage trying to measure
ADn- = negative side or common ground
where n is one of 1,2,3,4.

You can do a quick check of the A/D inputs by selecting the FlashScan options: F4->F4->F4 which will display the voltages form all 4 A/D inputs on the FlashScan screen.
Then connect a 1.5V battery to any pair of +/- A/D inputs and see if the voltage is registered.

Joecar...it is hooked up correctly.
Blacky...I did all that already and the readings are stuck on 1. It doesnt change values even when i disconnect the power source.

It sounds like one or all of the A/Ds have failed. You should return it to the place of purchase for warranty/repair.
