k-line
English translation:
type of Data Communication Network Interface (DCNI) standards for vehicles
Explanation: The following references seem to make clear that the k-line is one type of Data Communication Network Interface for vehicle diagnostics. The two websites, especially the .edu one may be of some use to you overall.
"To make things a bit more complicated, Diagnostic Trouble Codes can either be "generic," i.e. the lowest common denominator, or "enhanced," i.e. include codes used only by specific manufacturers. General Motors, Ford, and Chrysler all have their own set of enhanced codes. A standard OBD-II scanner can read all those codes, but not necessarily interpret them as they may apply to a single vehicle of a particular model year. Automotive networks And it doesn't stop there. There are also different Data Communication Network Interfaces (DCNI) for vehicles. In the US, SAE specifies "Class 2" J1850 VPW Variable Pulse Width (GM) and "SCP" J1850 PWM Pulse Width Modulation (Ford). Internationally, the ISO specifies the "K-line" 9141-2 standard (also used by Chrysler) and on newer vehicles the "KWP2000" 14230-4 standard. The Canadians use yet another standard. Not all of these protocols use the same pins on the connector, and sometimes it is possible to determine the protocols just by looking at what pins are present. http://www.pencomputing.com/frames/obd2.html

Various Data Communication Network Interface (DCNI) standards for vehicles exist. SAE specifies J1850 VPW (widely used by GM, also known as Class 2) and J1850 PWM (Ford, a.k.a. SCP), while ISO specifies the 9141-2 (most imports and some domestic, a.k.a. "K-line") and 14230-4 (some newer imports, a.k.a. KWP2000). https://www.msu.edu/~guentche/guentchev/OBD-II/details.html#... glossary

the wire on which the control modules in the car communicate with the diagnostic tool
Explanation: The problem of the k-line shorting to ground appears to relate to the use of "aftermarket radios" (that is, a radio different from the one originally fitted), specifically in VW cars. In 1998 VW and Audi introduced diagnostics-capable radios, making it possible to connect the k-line from the scan tool to the radio (to check the car computer for faults). However, some replacement radios (like earlier VW radios) have the k-line port connected to the 12V battery input, with the result that when the k-line is connected to that port it shorts to ground.
