B00D2 — Restraint System (SRS) Indicator 1 Malfunction

Severity: medium Safe to drive

What B00D2 means

The restraint (SRS) control module continuously monitors the warning lamp circuit that tells you about airbag and seatbelt system problems. B00D2 means a fault was detected in the circuit for indicator 1, such as an open, short, poor connection or a lamp that is not being controlled properly. The exact meaning of the subfault can differ by manufacturer.

Symptoms

  • Airbag / SRS warning light is on or flashing
  • Warning light does not come on during the bulb check at ignition on
  • Fault code stored in the restraint control module
  • Possible restraint system warning message in the display

Possible causes

  1. Fault in the indicator or its circuit in the instrument cluster
  2. Damaged, corroded or loose SRS wiring or connectors
  3. Poor contact at connectors under the seats or at the steering column
  4. Communication problem or internal fault in the SRS control module
  5. Software or coding error after repairs or part replacement

How to diagnose

  1. Scan all modules with a tool that supports SRS and note freeze frame data and any other airbag codes
  2. Watch the SRS lamp at ignition on: does it light and then go out after a few seconds?
  3. Check battery voltage and terminals, since low voltage can set false codes
  4. Inspect SRS and instrument cluster connectors and harnesses for corrosion, moisture and damage
  5. Disconnect the battery and wait the time specified by the manufacturer before touching any SRS connector, to avoid accidental deployment
  6. Test the indicator circuit against the wiring diagram: power, ground and wire continuity
  7. Check the instrument cluster and its data bus communication with the SRS module
  8. After repair, clear the code and confirm it does not return

Common fixes

  • Repair or replace damaged SRS wiring and connectors
  • Replace the faulty instrument cluster or indicator lamp
  • Replace or reprogram the SRS control module if the fault is internal
  • Clear the code and verify the system with a professional scan tool

Questions and answers

Can I drive with code B00D2?

Engine and brakes are usually unaffected, so you can drive. But the airbags may not work in a crash, so get it diagnosed as soon as you can.

Can I just clear B00D2?

Clearing only hides it for a while. If the cause is still there, the light will come back, so find and fix the circuit or indicator problem first.

Why shouldn't I work on SRS wiring myself?

Airbag connectors are tied to the inflators, and a mistake can set one off. Disconnect the battery and follow the wait time, or have a shop do it.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
