All Models - Control Module Coding Information

Updated to Include Test Character Screen Information.

When long coding a control module through Vehicle Self Diagnosis, the first screen may request a test character to be entered (Fig 1). DO NOT enter a value on this screen. Select "Q" to go to next screen.

Select the "OK" button on the pop up screen that follows (Fig 2) to go into the actual long coding.

The screen should display the Hex Bytes on the left side of the screen at that point. Click on a Hex Byte to pull up the keyboard in order to change the Byte. Once all Bytes are changed, remember to press the forward arrow in order to submit the new coding into the module.
