trouble reading pids

[nick123]

hi my brothers truck pcm can be read and tuned but not scanned...

i have 2 other trucks that scan no problem

with the v2 attached to the odb 2 and the v2 connected to my laptop i enter the vin in the scan tool select the engine size also....
so far so good! the pids have no x through them and appear to be supported!

now i click connect, yellow button in the scan tool

only 3 pids are valid ... the rest have a red x and there is no data from any selected or valid pids

truck is an 03 sierra 1500 5.3 lm7
please help

Post screenshots of these tabs from scantool right when the connections fails: Console, OBDII->Summary, OBDII->Modules, OBDII->Controller, PIDs.

I have recently ran into the same problem with my 2000 Corvette. 2004 Escalade worked fine but the Corvette would only report Air Mass Per Cylinder, Injector Duty Cycle Bank 1, Injector Duty Cycle Bank 2, and Power At Wheels. However, nothing would record when the red or yellow bttons were activated.

In scantool, go Edit->Properties->Connection and set Preferred Cable Type to EFILive FlashScan V2.5 HAPI, and click Ok.

Thanks Joe, I will do this later today and let you know the results.

[Gordy M]

Just check my scantool. It was already set to the V2.5 HAPI. Problem still exists when I loaded the Imperial PID selection, only three were reported and all the other were non reporting with the RED X. Ran the DTC and have U1096, U1064 and U1016 H codes. Somehow the OBD II connection is not being recognized by EFILive V2, yet it will power up the V2 FlashScan.

After trying to log data, select the menu option: File->Generate error report, send the error report to me at paul@efilive.com, include a link to this thread so I know what its about. I'll see if I can determine what has gone wrong.

Hi Guys, I am having similar problems and will email you Paul with my error reports

[John02SS]

We ever get a solution to this?

[joecar]

It looks like it was dealt with offline.

If you're having some problems, please post some screenshots.

I'm having similar issues. I'll try one more round then may be back

I had this same exact issue recently. It occurred and would randomly fix itself. It happened on car B with an LS1B 09360361 after I had previously been connected to car A with an LS1B 12587604 / 04110003.
To fix it, I had to manually click the button "Check support for each PID" (2nd row of buttons on mine and 2nd button from the left).

Could also do (from V7 scantool): Info->Validate Pids.
