Toyota Diagnostics

 We regularly undertake vehicle diagnostics and specialist electronic repairs including electronic control module replacement to Toyota vehicles. Based in Norwich with easy access from any part of Norfolk we also offer a Europe wide mail order service. If you have a faulty Engine control module (ECU) you will be aware that they are programmed to the vehicles Immobiliser system and cannot be simply swapped with a working unit from another vehicle. A diagnostic scanner used by garages & workshops does not have the capacity to program secondhand ECU's, however we are able to make secondhand units work on Toyotas by transferring data files (Bench programming or 'Cloning') This will enable a secondhand to be re-used with no further programming necessary making it 'Plug & Play'. We have hundreds of ECU's in stock - call us to see if we have a Toyota ECU for your vehicle. If you have already purchased an ECU for a Toyota and need it programmed we offer a cloning service from 50+vat, Call for more information.

Toyota Airbag Crash data removal

 We can remove crash data from most airbag control units fitted to Toyota vehicles. Crash data needs to be removed from SRS control units after a car has had collision and a safety feature has been activated such as seat belt pre-tensioners, airbags, fuel cut-off systems etc. This usually appears as the airbag warning light being illuminated and fails to extinguish when garages try to clear fault codes with a standard diagnostic scanner. Simply remove your airbag control unit, bring it to us for stripping and re-programming and usually it will be ready for collection within 24 hours, Prices start from 40+vat

Mail order service available
