Volvo Diagnostic Codes 1996 to 1998

Volvo 850, S70, V70, C70, XC70 Trouble Codes 1996-1998

A Little Background

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, “is something wrong? Well then let’s record and remember it for the owner or technician.” 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
