B00D3Restraint System Malfunction Indicator 2
- Generic OBD-II code · Body
- How the car detects it
- B00D3 refers to a second restraint malfunction indicator. No carmaker documents which lamp that is, so its meaning has to be inferred. One reading is a backup for the main lamp: the 1995 Saab 900 calls its SRS light warning lamp 1 and switches the central warning lamp on for good if that circuit fails. Saturn patented a similar fallback in 1991, using the seat belt lamp as second SIR indicator once a voltage check or photocell shows the airbag lamp is dead, flashing ten times and then glowing for ten minutes, or flashing constantly. Another reading is a separate telltale, since FMVSS 101 names a side air bag malfunction lamp besides the main airbag lamp. In either case B00D3 reports a fault in that second display circuit, not in the airbags themselves.
