Reading your car

Now that the V-Switch software has been installed and the device linked to your computer and car,
it is time to plug into your vehicle and take a read of the car’s software.

To plug into your vehicle, locate the OBDII Diagnostics port; this is usually located on the driver’s side
of the vehicle, underneath the dashboard above the pedals, to the side of the pedals or under a
panel in the center console.

PORT**(Or speak with your local Vehicle Franchised Dealer)

Once located, connect the V-Switch to the car using the OBDII cable that is provided.

Once plugged in, select “Read file from ECU” and follow the on screen instructions.

The device will then take you through a number of instructions and options. Most of these are
ignition stages, asking you to turn the ignition on:

This is to ignition 2. Ignition 2 is the ignition stage just before the engine will turn over, an indication
that you have correctly selected ignition 2 is that the dash lights will turn on and the engine
management light will remain on.

The reading process takes around 15 minutes, however depending on the vehicle can take more or
less time.

Once the read is complete, disconnect the V-Switch from the vehicle and plug it back into your
computer.

Please note*** Taking the read from your ECU will NOT affect the operation of your Vehicle.
