Testing procedure
–  Remove the air filter → Chapter.
   
–  Detach the connectors -1- from the injectors -2-.
–  Attach diode lamp -V.A.G. 1527-, using auxiliary cables -V.A.G. 1594-, to the contacts on cylinder 1's connector.
–  Operate the starter motor. The diode should blink.
–  Repeat the test on the injector connectors corresponding to cylinders 2...4.
If the diode does not blink:

–  Check for a break in the cables between the test box and the injection connector, following the wiring diagram. Connector cyl. 1, contact 2 + female socket 73 Connector cyl. 2, contact 2 + female socket 80 Connector cyl. 3, contact 2 + female socket 80 Connector cyl. 4, contact 2 + female socket 73 Cable resistance: 1.5 Ω max.
–  Also test whether the cables are shorted between each other. Theoretical value: ∞ Ω.
