In order to regulate the increasing number of vehicle anti-theft devices in Japan, the Japanese Ministry of Land, Infrastructure and Transport on July 7, 2003 revised its safety standard for road vehicles in Japan (hereafter, "Safety Standard"). Enforcement of this new Safety Standard went into effect on July 1, 2006.
 

This revised Ministerial Ordinance provides concrete technical standards pertaining to anti-theft devices -- Ministry of Land, Infrastructure and Transport Regulation Notice#619: 54th Provision (anti-theft alarms), 110th Provision (anti-theft alarms), and 78th Addendum (anti-theft device technical standard).
 

A summary and main points of interest concerning this Safety Standard are presented below.

Q1: What is inspected when testing conformity to this technical standard?

The following 6 areas are covered by conformity testing:
 

1. Cyclic Testing (-40°C to +85°C for anti-theft devices mounted inside vehicle, and 125°C for anti-theft devices mounted in the engine compartment) must reveal normal operation of the anti-theft device in the installed environment. Devices (such as sirens) installed in the engine comparment are subject to strict -40°C to +125°C heat-resistance temperature tests in addition to IP54 waterproofing, dustproofing and vibration tests.
2. Endurance Testing: the main siren of the anti-theft device must not fail, over-heat, short-out, or otherwise respond abnormally under testing
3. Basic Safety Testing: verifies that no fire is caused by potential wiring mistakes made by installers
4. Safety Testing of Anti-Theft Device Attachments: confirms the safety of the anti-theft device when connected to ultrasonic sensors, shock sensors, and other such external sensing devices.
5. Sound Pressure Testing: verifies that the sound intensity does not exceed the limit of 100dB @ 2 meters.
6. Verification of conformity to the Japan Radio Law (RF frequency/intensity/wireless noise, ARIB STD).
 

Q2: What kind of vehicles are subject to the Safety Standard regulation?

All passenger cars that are newly registered on or after July 1, 2006, weighing less than 2-tons and operating on a 12v power source, are subject to the regulation. "Light Motor Vehicles" or "K-cars" are subject to the regulation from July 1, 2008. Confirmity to the Safety Standard is only required when an anti-theft device is installed to the aforementioned vehicles (in Japan).
 

Q3: Does VISION recommended installation of a compliant anti-theft system in new cars?

Yes. If a non-confirming anti-theft device is installed, it is likely that the vehicle will not pass regular inspection (in Japan).
