B00D3 code meaning
Restraint System Malfunction Indicator 2
What B00D3 means
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.
B00D3 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B00D3
- Airbag lamp on, second indicator dark or not doing its bulb check
- Backup warning missing if the main airbag lamp also fails
- Safety note: restraint warnings incomplete; work on cluster and wiring only de-energised (ignition off, battery off, wait time), specialist workshop only
Common causes of B00D3
- Most likelyOpen or shorted circuit to the second restraint indicator
- PossibleSecond indicator lamp or LED failed
- Less likelyRestraint module or cluster configured for an indicator the vehicle does not have
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B00D3 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| D3 | The exact fault in that area. |
What to do next
- Note B00D3 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
