B00D5

What it means

B00D5 means the restraint (airbag) control unit has found a fault with the passenger airbag disable indicator, the light that tells occupants whether the front passenger airbag is on or off. The control unit checks the indicator circuit and its commanded state, and sets the code when the circuit or its feedback is open, shorted or does not match what it expects. The exact fault conditions and wiring vary by model, so check the manufacturer's data for the vehicle.

Symptoms

• Passenger airbag on/off indicator stays lit, stays dark or does not light during the bulb check at start-up
• Airbag warning light on the dash
• Indicator flickers or changes state without the occupant status changing
• Unable to tell whether the passenger airbag is enabled or disabled
• Fault logged in the restraint system but no other airbag faults present

Possible causes

• Faulty indicator lamp or LED module (often part of the dash, centre console or roof panel)likely
• Damaged wiring, poor connection or corroded terminals in the indicator circuitlikely
• Faulty passenger occupant detection or classification system giving an implausible status to the control unitpossible
• Manual passenger airbag switch (where fitted) faulty or giving an incorrect signalpossible
• Low battery voltage or a recent loose connection or disturbance after seat, trim or battery workpossible
• Faulty restraint control unit or outdated software, if the manufacturer lists this as a known issuerare

How to diagnose

1. Read all stored and pending codes from the restraint system and other modules, and record freeze frame or status data where available
2. Switch the ignition on and watch the indicator and airbag warning light during the bulb check, noting what the indicator does
3. Check the battery condition and charging voltage, as low voltage can set restraint faults
4. Visually inspect the indicator unit, the passenger seat and the connectors under the seat and dash for damage, trim disturbance, spilled liquid or corrosion
5. If a manual disable switch is fitted, operate it and check the indicator and any live data respond correctly
6. Following the manufacturer's SRS safety procedure (battery isolation and wait time), check the indicator circuit connectors for pushed-out pins, damage and tightness
7. Check the circuit continuity and resistance to the manufacturer's values, and do not probe airbag firing circuits
8. Check for manufacturer service information or software updates relating to this code for the specific model

How to fix

• Replace the faulty indicator lamp or display module
• Repair or replace damaged wiring, and clean or replace corroded or loose connectors
• Repair or replace the faulty occupant detection or classification components, and carry out any required calibration or setup
• Replace a faulty manual airbag switch
• Correct the battery or charging problem, then clear the code and confirm it does not return
• Update or replace the restraint control unit only if testing or manufacturer information confirms it is at fault
