The Communication Line Check

While in the self-diagnostic mode, the Communication Line Check starts after the LCD Segments Check.

If all segments come on, the communication line is OK. If there is a communication line error, the word "Error 1" will be indicated on the LCD display.

If the communication line error is found, go to system troubleshooting (see DTC TROUBLESHOOTING ). If the communication line error is not present, check for body DTCs with the HDS (see HOW TO CHECK FOR DTCS WITH THE HONDA DIAGNOSTIC SYSTEM (HDS) ).
