What does B2445 mean?

B-code B2445 means "Passenger Side Crash Sensor Internal Fault". It is a generic OBD-II diagnostic trouble code (DTC) in the body electronics. A fault has been detected in the passenger side crash sensor internal fault — the control module has logged this condition during self-diagnostics. This code can be monitored, but service is recommended to prevent escalation. This code applies to OBD-II compliant electric and hybrid vehicles.

Possible Causes

  • Faulty or failed component in the body electronics
  • Damaged or corroded wiring and electrical connectors
  • Control module software error or firmware fault
  • Poor or missing ground connection at the affected module

Recommended Actions

  1. 1 Note the alert and schedule a diagnostic appointment when convenient
  2. 2 Scan for all DTCs with an OBD-II scanner — note any related codes stored alongside B2445
  3. 3 Inspect the body electronics component and its wiring for visible damage
  4. 4 Check for water intrusion in connector areas and clean contacts if corroded
  5. 5 Clear the DTC, road-test the vehicle, and re-scan to confirm whether the fault returns
  6. 6 If the fault persists after inspection and clearing, consult an EV-certified technician for component replacement
