There are 7 system functions we can test, I’m going to show the status of ignition switch, so press “Status of circuits”.

 

As you can see, the “Circuit 15C/15R” are my ignition, like ignition feeds, which are “OFF”.

My transmitter key is “Not Active”. My circuit 50 which is my main feed. When my ignition is turned, it is also “OFF”. so what I’ll do is to insert the key.

 

Look, Circuit 15C has come on. I’m going to turn my ignition on, so my lights on the dash. If you now notice my ignition switch on, signals are all activated. And the only one at the minute that’s off is my start signal.

 

So if I press my brake and try to start the vehicle…Have a look, the EIS is sending the signal out. So the vehicle started, it went to on then went off again. That means it sent the signal to the vehicle ECU and the relevant modules for the car to start.
