November 11th, 2008Though some of the car models do have an electronic control system which allow storage of sensor data which can be used to diagnose a problem, many cars on the road still do not have this system inbuilt. Also the electronic control system may not be able to detect a mechanical problem related to suspension.
To diagnose the problems, most garages, alignment, suspension and brake shop will use a diagnostic machine will carry out the following tests and do many other checks:
- Fuel pressure
- Ignition coil output
- voltage at spark plugs
- spark plug mis-fire conditions of emissions related systems
- Amount of electricity needed to start the car
- battery voltage
- charging voltage
- condition of fuel injectors
