What Does B00D5 Mean?
This code indicates a malfunction in the passenger airbag disable indicator system, specifically a subfault detected by the restraint control module. The system monitors the passenger occupant classification sensor and the dashboard indicator lamp that shows when the passenger airbag is deactivated. The control module has detected an electrical fault, communication error, or component failure within the indicator circuit that prevents proper notification of airbag status to the vehicle occupants.
Common Causes
35%
Faulty passenger airbag disable indicator lamp or LED in instrument cluster
30%
Wiring harness damage, corrosion, or connector issues between restraint control module and indicator lamp
20%
Occupant classification sensor malfunction or calibration error
10%
Restraint control module internal fault or software corruption
5%
Instrument cluster communication fault or internal failure
Diagnostic Steps
1
Step 1: Perform visual inspection of the passenger airbag indicator lamp in the instrument cluster - verify if lamp is illuminated, flickering, or inoperative during key-on self-test cycle
2
Step 2: Inspect all connectors at the restraint control module, instrument cluster, and occupant classification sensor under passenger seat for corrosion, pushed-out pins, or damage - wiggle test connectors while monitoring live data
3
Step 3: Using a digital multimeter, check voltage supply and ground circuits to the indicator lamp at the instrument cluster connector - verify presence of 12V supply and continuity to ground per manufacturer specifications
4
Step 4: Access restraint system live data and verify communication between restraint control module and instrument cluster - observe passenger airbag status indicator commands and actual indicator response
5
Step 5: Test occupant classification sensor output by placing calibrated weights on passenger seat while monitoring sensor voltage/resistance values - compare readings to specification ranges
6
Step 6: If all circuits and sensors test normal, perform instrument cluster self-diagnostics or consider cluster replacement/reprogramming; clear codes and verify indicator operates correctly during system self-test

The most common cause of B00D5 (Restraint System Passenger Disable Indicator (Subfault)) is: Faulty passenger airbag disable indicator lamp or LED in instrument cluster
Typical repair costs for B00D5 range from $150 to $850, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle is generally safe to drive, but the passenger airbag status indicator may not accurately inform occupants whether the passenger airbag is enabled or disabled, which is a critical safety concern especially with child seats. This is a compliance issue that requires prompt repair to ensure proper airbag system notification and should be addressed within a few days.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B00D5 to identify the root cause.
