Hi,
Are you talking about OBD codes?
B5 is the port for OBD DTC codes.
I don't find 1-1-1-1-1 listed in the pocket data book.
I do have the SRS wiring info from the 1993 240 manual that I can send to you.
Provide an email address.
The B5 codes report from the SRS sensor module called a "Crash Sensor"
in the 240 manual. It's under the driver's seat.
Proceed with caution when working with SRS connectors/grounds etc.
Disconnect the battery and wait ten minutes before servicing SRS grounds etc.
There's special manuals for Volvo SRS but so far I haven't seen one.
Bill
