Volvo Diagnostics, the second version, was introduced in 1991 meant that additional services were made available, such as:
- Possibility to control transfer rate for data between the control module and the diagnostic socket.
- Individual activation of components/functions (check function 4).
- Read in and out signals (check function 5), where every value is represented by a three-digit code.
- Enter data (check function 6), where you could enter data via three-digit codes.
Services are introduced to varying extent on the different control modules.
The diagnostic socket with light-emitting diode is used to read out Volvo Diagnostics from the various control modules.
The tool Volvo Diagnostic Key and then Volvo System Tester were introduced to make communication easier with the control module.
