There's all kinds of minor build deficiencies with this clone. I'm not happy with this Tech 2 Chinese pile of junk. I'm wondering if the lack of communication with the modules is the reason for the communication error. I have a better shot at narrowing down the problem with a solution. I hate guessing but I wonder if the BCM is done? I'm not the type of guy that's gonna swap out anything until I have a high degree of certainty. The Two DTC's are Instrument Panel Cluster, U1000 Class 2 DATA LINK Malfunction, and B1384 Device ignition accessory circuit open. The Tech 2 diagnostic pulled two DTC's and cannot communicate with other modules. Checked out all the fuses replaced and relearned the ignition switch, (no passlock light after relearn), tried everything to no avail. You see I'm trying to chase down a no crank issue. Looked at the Baud and its 115.(the highest default setting). Tried the DLC Female Power Receptacle Cable with ac power. you can suffer dropouts in the Class 2 Network Communication during Pass-Thru activities.

if the PCM is not likewise getting stable juice from the car Battery. Even though you're Powering the Tech2 using a Steady AC/12 VDC Wall Power Source.

make certain to Turn Off or Disable everything you can think of inside of the vehicle that draws any Juice from the 2007 Saturn Battery as well after Freshly Cleaning the Positive and Negative Battery Cable Connections as well. You've thought of all this already, I'm sure.But jik. Then you might be getting some problems with subtle Voltage Drops and Fluctuations. right where it Plugs into the Female OBD2 Port under the dash. and/or if you're Powering the Tech 2 through the Bottom of the Tech 2 Hand Held Scanner Power Interface using 12VDC 1 Amp A/C Wall Power Unit instead of attaching that same Power Connector directly through the DLC Cable Female Power Receptacle on the OBD2 Adapter End. Can you check the Settings for the Com Ports and INCREASE THE BAUD RATE and see if that has any Positive Effect? If your Battery is NOT right at Tip Top Shape and/or not holding above 12.7 VDC or Better.
