1. Disconnect high voltage wires from spark plugs.
2. Remove the spark plugs and reconnect the high voltage wires to them.
3. (3S-FE, 3S-GE, 4A-FE, 4S-FE, 5E-FE and 7A-FE serial version) ground (connect with "weight") spark plug housings.
(4A-FE with Lean bum) Pull the ends of the wires 12.5 mm away from "masses" (car body).
Check for sparking when cranking the engine with the starter.
Note: to prevent a significant amount of fuel from running injectors from entering the engine cylinders, the test should be carried out for no more than 1-2 s.
If there is no sparking, perform the test described in the subsection below "Checking the elements of the ignition system or elements of the integrated ignition unit (non-contact ignition system)".
