Codes: 1996 to 1998 Volvos

A Little Background on On Board Diagnostics

OBD-II grew out of an effort in the late 1960s by Volkswagen to computerize the monitoring of an automobile’s running status. The thinking went like this:

Is something wrong with the car? Well then let’s record it, remember it, and spit it out for the owner or technician.

That’s what your Volvo does. That’s where On Board Diagnostics came from.

The US state of California required all 1991 new cars to have a computer that would not only facilitate this recording of faults, but provide a common method of retrieving them across brands and models [citation]. It was an open format, in other words.

The “Middle” Year Volvos: 1996-1998

OBD-II diagnostic trouble codes are 4-digit, preceded by a letter:

  • P for engine and transmission
  • B for Body
  • C for Chassis
  • and U for Network
