Last updated: 07 Oct, 2013

After PCM replacement, there are some simple steps to follow using the wiTECH Diagnostic Application to properly connect to the vehicle:

  1. Open the wiTECH Diagnostic Application, select your device in the Connection Wizard, and click on Next.
  2. Log into DealerCONNECT.
  3. In a few moments, a pop-up Vehicle Identification window will appear (see below). Cycle the ignition key and then click on Continue.




  1. Enter the full 17-digit VIN from the connected vehicle and click on Continue.




  1. The message shown below will now be displayed, prompting the user: “If this is a replacement PCM, you may also need to flash reprogram the PCM.”




  1. If the PCM requires a flash to function properly, you must now flash the PCM by navigating to the PCM Flash Tab as shown below.




  1. After the PCM flash is successful, proceed to run the appropriate Misc. Functions for the connected vehicle (PCM Replaced, Learn ETC, Check PCM Odometer, etc). 
    • The Misc Function information is in DealerCONNECT under the Service tab > Service Info > 28 - DTC Based Diagnostics > MODULE, Powertrian Control (PCM) > Standard Procedure > PCM/TCM Programming.

Following these steps will help to ensure an efficient PCM replacement process.
