Checking injection amount

- Insert injector to be tested into measuring glass of VAG1602 fuel
analyzer.
- Connect one terminal of injector being tested to engine ground using
test lead from VAG1594.

This step lets the fuel pump run without the engine running. The closed
throttle position switch must be closed during the test, or the selected fuel
injector will discharge fuel when it is actuated 5 times. - Connect second terminal of injector to B+ using VAG1348/3A remote
control, VAG1348/3-2 adapter wire and an auxiliary wire.
