"D" is the 26-Way D-Type Connector that screws into your Tech2, "D-4" is 26-Way D-Type pin 4. "DLC" is the Datalink connector (the connector that pushes into the vehicle) so "DLC-2" is Data Link Connector pin 2. I know the PCM has two connectors and I probably should see if there is continuity in the purple wire (Pin 2) and its termination in one or the other connector. I am trying to locate a wiring diagram for the PCM and DLC which will give me a better understanding of the wire mapping. I am not sure what to think, whether the issue is with the PCM or wiring.

Checked the purple, black, black/white and orange wires on the back of the DLC for integrity and did not find any issues with fraying or looseness.

Tested DLC pins 4 and 16 (battery) and the voltage was 12.58.

Performed a volt reference check on DLC pin 2 (serial data) to determine if it was 5 volts and actual voltage was between 1 and 2.

The voltage was less than 0.1 which led me to believe low resistance.

Tested DLC pins 4 (chassis ground) and 5 (PCM ground).

Verified that the Power Control Module (PCM) and Data Link Connector (DLC) fuses were okay.

I performed troubleshooting by doing the following: The scanner is operational and can scan all protocols but can not link to any of them. I recently purchased a clone GM Tech2 scanner to access the diagnostics in my 2006 Hummer H2. Hope it may help you when you meet the same This post collected the problem “OBD2 Port Not Communicating with Vetronix Tech 2 Scanner ” from the user and offered the way to deal with. Note: Tech1 adaptor TA02149 will only work on the 12 pin DLC connectors that are typically found on model year 1993 and prior. Select programming, model year, 4th digit of the vin, select the module (CCM), Program CCM, select location (North America), enter the rest of the vin, select transmission type, odometer select (miles or kilometers), enter odometer reading, programming is complete. Install the Tech 1 with VIM cable adaptor P/N 3000091.

Install Tech 2 and request information from the vehicle, download PCM calibration from TIS to the Tech 2 and then upload to the vehicle. Remove class 2 line from DLC pin position number 2. Note: The PCM must be programmed prior to programming the CCM if both have been replaced. It may be found that the option F0 : PROGRAM CCM is not available on the Tech I. The following process should be used to program a service (replacement) Central Control Module (CCM) on a 1994-1996 Corvette. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. 10) Select the Reset J2534 Tool box and then select Next to set up a different J2534 tool.Ĭhinacardiags found a good way to solve unable to program the Central Control Module (CCM) using Vetronix Tech2. If the J2534 tool selection needs to be changed, there is now a check box that must be selected next to the Select Programming Process menu on the Select Diagnostic Tool and Programming Process screen. Once a J2534 tool has been selected, reprogramming of a control module can be completed. The first time the J2534 Tool option is selected, a screen will appear asking the user to select a device type, such as the MDI, MDI 2 or other tool. J2534 is an interface standard designed by the Society of Automotive Engineers (SAE) and mandated by the US Environmental Protection Agency (EPA) for vehicle Electronic Control Unit (ECU) reprogramming.įrom the Select Diagnostic Tool and Programming Process screen, select the J2534 Tool option for all J2534 tools (MDI, MDI 2, or other J2534 device). GM has recently updated the Service Programming System (SPS) with a new method of selecting a J2534 tool in TIS2Web.Ī J2534 tool ( MDI, MDI 2, or other J2534 device) is required in order to manage the transfer of data between a vehicle’s onboard network and a service technician’s PC.
