B00D2 Restraint System Malfunction Indicator 1

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

B00D2 means the restraint module has found a fault in the circuit of its primary warning lamp, the airbag or SRS light. FMVSS 208 S4.5.2 requires such a readiness indicator, watching its own readiness and within the driver's view, and FMVSS 101 lets it push other messages out of a shared display. No carmaker publishes B00D2. Saab shows what the check looks like under its own older numbers: on the 1998 9-3, B1227 is set when the lamp output reads above 5 V for 1.25 s, a short to positive that keeps the lamp from its 3 to 4 s bulb check, and B1228 when it reads below 1 V or above 10 kOhm while off, an open or short to ground that turns on the central warning lamp instead. Until fixed, the driver may not see further airbag faults.

Likely causes

Bulb or LED of the airbag warning lamp failed
Lamp lead open, shorted to ground or to battery voltage, or loose cluster connector
Internal fault in the instrument cluster circuit board

Symptoms

  • Airbag lamp does not come on for the bulb check at ignition-on, or stays on
  • A substitute warning such as a central warning lamp or a tone may appear
  • Safety note: airbag faults may go unnoticed; work on cluster and restraint wiring only de-energised (ignition off, battery off, wait time), specialist workshop only
