DI[AG]

Description

After the DIAG command is entered, the following prompt is printed on the terminal:

(diagnostics)SElftest #     (DTC Selftest)PRint    #,#,# (Print to specified port)Internal #,#,# (Internal loopback on specified port)EXTernal #,#,# (Loopback through hood on specified port)Terminal #,#,# (Write and read to terminal on that port)XInternal#,#,  (Internal loopback on specified SNP card)XExternal#,#   (Loopback through hood on specified SNP card)XNetwork #,#,# (Loopback on the highest and lowest VC)(carriage return to exit) ?

These are the subcommands that can then be entered. The following pages describe each of these options.

If you press [Return] instead of one of the subcommands, you will be returned to the major prompt and can then enter another TermDSM command.

[CTRL]-Y can be used during execution of any of the above subcommands to stop the diagnostic looping. However, the current loop will always complete before the [CTRL]-Y takes effect. In the case of the DTC selftest, this can take several minutes.
