EV Crash Safety Module & Pyro‑Fuse Controller Repair London | FixAnyEV

🚨 EV Crash Safety Module / Pyro Fuse Controller Diagnostics & Repair

Mobile SRS Airbag ECU Repairs, Pyro‑Fuse Reset, HV Isolation Faults & Post‑Crash Recovery

Electric vehicles contain advanced Crash Safety Modules that control:

  • Airbags
  • Seatbelt pretensioners
  • Crash sensors
  • Pyro‑fuse activation
  • HV battery isolation
  • Post‑crash safety shutdown

When a crash is detected, the Pyro Fuse Controller may disconnect the high‑voltage battery to protect occupants and emergency responders. This can leave the EV unable to start, unable to charge, or completely immobilised — even after minor impacts.

FixAnyEV provides mobile Crash Safety Module diagnostics, SRS repairs and pyro‑fuse resets anywhere in London.

📞 Call 07779 836 677 for crash‑safety diagnostics.

⚠️ Crash Safety Modules are life‑critical — incorrect repairs are dangerous. ⚠️ Pyro‑fuse activation disables the HV system and must be reset or replaced correctly.

🔧 What the Crash Safety Module Controls

✔ Airbag Deployment Logic

  • Front, side, curtain airbags
  • Seatbelt pretensioners
  • Occupant detection
  • Impact severity calculation

✔ Pyro‑Fuse / HV Battery Isolation

  • HV battery disconnect
  • HV contactor shutdown
  • Emergency isolation logic
  • Post‑crash lockout

✔ Crash Sensor Network

  • Front impact sensors
  • Side impact sensors
  • Rollover sensors
  • Pedestrian impact sensors

✔ Post‑Crash Safety Mode

  • HV system disabled
  • Charging disabled
  • Drive system locked
  • SRS warning active

🚗 Symptoms of Crash Safety Module / Pyro‑Fuse Faults

  • “Airbag Fault”
  • “SRS System Fault”
  • “High Voltage System Disabled”
  • “Service Safety Restraint System”
  • EV won’t start after minor impact
  • EV won’t charge
  • HV isolation fault
  • Pyro‑fuse blown
  • Seatbelt pretensioner fault
  • Crash data stored in SRS ECU

⚠️ A blown pyro‑fuse will immobilise the EV until repaired.

🧠 Common Causes of Crash Safety Module Failure

  • Minor collision
  • Kerb or pothole impact
  • Airbag deployment
  • Seatbelt pretensioner activation
  • Water ingress in SRS ECU
  • Low 12V battery during SRS self‑test
  • Incorrect jump‑start procedure
  • Corrupted crash data
  • Faulty impact sensor
  • Pyro‑fuse degradation

🛠️ Our Crash Safety Diagnostic & Repair Process

  1. Full SRS scan – airbags, pretensioners, crash sensors, pyro‑fuse
  2. HV isolation status check
  3. Crash data analysis
  4. Pyro‑fuse testing & replacement
  5. SRS ECU reset or replacement
  6. Impact sensor testing
  7. Post‑crash HV system reactivation
  8. Final safety validation

⚠️ Some EVs require secure access to re‑enable the HV system after a crash event.

🔒 Crash Safety ECU Coding & Secure Access

Many EVs require secure access to:

  • Reset crash data
  • Pair a new SRS ECU
  • Re‑enable HV battery contactors
