Default ProDiag/VAD Mobile, "ECU not present or not responding" HELP?

I keep getting this message trying to connect. I've used this on my Palm Tungsten dozens of times w/out problem. Cord is solidly connected at both ends. Green light is on until it tries to connect, then it turns red. I tried messing w/ the connection baud rates--no luck.

anyone btdt?

Default over time we started experiencing that quite a bit...

with the old Pro Diag units. Evidently HPA / VAD have revised that connection for the better.

Default Flint, can you please check.....

1. Ensure the pins on the OBD-II end of the cable are straight and of an even depth. (There will be 2 pins that are longer in the middle, that is ok)

2. Wiggle the Palm connector that attaches at the bottom of your Tungsten when it is trying to connect. See if anything happens.

Are you using the one piece changing cable or 2 piece serial/OBD-II cable?

Default If it is a Palm Tungsten E2.....

I would strongly suggest purchasing the 1 piece charging cable. E-mail me at darryl@vadpro.com and I will help you out.
