After a collision the first question is not about the paint, but: whether the HV pack is sealed and safe. Toyota and Lexus have procedures for HV technicians — the driver should know the basic warning signs.
When not to drive on?
- A “sweet” chemical smell from the boot or under the seat
- HV fault codes immediately after the impact
- Battery coolant leak or a deformed case
- Isolation: crackling, sparks, smoke when connecting a charger (PHEV)
Diagnostics after the damage
An isolation measurement, inspection of the orange connectors, a fault scan and a module test. Sometimes a case or fan replacement is enough, sometimes the whole pack, with documentation for the insurer.
Insurance
Keep photos, the police report and the estimate from an HV workshop. A rebuild is sometimes accepted if the report confirms no structural cell damage.
