Resolution
| 1. | If you have the ability, we would first suggest using a bench harness to read or flash the module in the vehicle. |
| 2. | If you do not have the ability to use a bench harness or the problem persists, start a support ticket and send us the following: |
| ￭ | A debug.dat file from your PC. |
| ￭ | A VCM Suite Infolog while connected to the vehicle. |
