Full Page Description: When a vehicle is involved in a collision, the damage goes far beyond what's visible. Modern vehicles rely on complex electrical networks, wiring harnesses, sensors and control modules that can be severely damaged in even a minor accident — and if these systems aren't properly diagnosed, repaired and documented, the vehicle is not safe to return to the road.

At National AutoTec, we specialise in post-accident electrical repairs for panel shops, smash repairers, insurance companies and private customers across Melbourne. Our fully equipped mobile service comes directly to your workshop or repair facility — minimising downtime and keeping your repair process moving.

Every post-accident electrical repair begins with a comprehensive pre-repair diagnostic scan, identifying all fault codes, damaged modules and affected systems before any work begins. This gives you a complete picture of the electrical damage and provides the documentation your insurer needs to approve the repair.

Our post-accident electrical services cover:

Wiring Harness Diagnosis & Repair Collision damage frequently results in damaged, shorted or severed wiring harnesses. We diagnose and repair damaged harnesses to manufacturer specifications — restoring full electrical function across all vehicle systems.

Sensor Replacement & Coding Modern vehicles are equipped with dozens of sensors that are vulnerable to collision damage. We supply, replace and code all sensor types — ensuring correct integration with the vehicle's electronic systems after repair.

Radar & Camera Module Supply & Coding After front or rear collision damage, radar units and camera modules frequently require replacement and coding. We supply and code these modules — and where ADAS recalibration is required after coding, we refer directly to our sister brand National ADAS Calibrations for a seamless, single-call repair process.

Module Replacement & Programming Collision damage can affect ECUs, BCMs, ABS modules and other control units. We supply, replace and program all affected modules — ensuring every system is correctly coded and communicating after repair.

Post-Repair Diagnostic Scan & Report Every repair is completed with a comprehensive post-repair diagnostic scan confirming all systems are functioning correctly. Our detailed reports are accepted by all major insurers and provide the documentation panel shops need to close jobs confidently.

Insurer Ready Documentation All work is documented to insurer standards — pre-repair scan, repair record, post-repair scan and system verification. Our reports are clear, professional and accepted by AAMI, Suncorp, IAG, Allianz, Youi and all major insurers operating in Melbourne.

Whether you're a panel shop needing a reliable electrical partner, an insurer requiring certified repairs and documentation, or a private customer needing post-accident electrical work, National Auto-Tec is Melbourne's trusted specialist.
