Reverse Radar for Toyota Corolla — Buying Checklist
Reverse Radar on the Toyota Corolla is one of the few items where the specification is not a matter of taste. This buying checklist covers what has to be checked before the part is bought, what the installation actually involves, and what has to be documented for the vehicle to stay insurable and road legal in your market.
Failures here are rarely dramatic. They are a supplier who changed material without saying so, or inconsistent hardness between lots — the kind of problem that shows up at the worst possible moment.

What to check before buying
- Fitment — confirm the model year and market version of the Toyota Corolla before ordering.
- Compliance — SAE J431 documentation should be issued with the shipment, not after it.

- Installation — check whether the vehicle wiring or trim has to come out first.
- Documentation — keep the test report with the vehicle record.
Installation notes
- Disconnect the battery before any wiring work.

- Record the installation date and the part number in the vehicle file.
- Re-check after the first week of use.

Questions buyers ask
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
