Why it helps
Lets the analysis and the fault-code tests use the correct ECU documentation for the variant.
Some cars come with more than one possible engine management system. For vehicles with technical data, if WrenchLane cannot tell which system your car has, the diagnostic form asks: 'Which engine management system does this vehicle have?' Pick one, or choose 'Not sure'.
The answer is remembered for the car, so the analysis and the fault-code tests use the right ECU documentation for that variant.
How to
- Open the diagnostic form for a vehicle with technical data
- Pick an option under 'Which engine management system does this vehicle have?' or 'Not sure'
Good to know
- Only shown for vehicles with technical data, in countries where that data is available (EU, EFTA and the UK).
- Only asked when several systems are possible and none is stored for the car. With a single candidate it is picked automatically.
- Your answer is saved for the car.
