Repair Volkswagen Passat B3-B4/Passat B3-B4>> System of ignition>> Check of system of ignition>> Check of system of ignition of Digifant
Ignition coil
Carry out check of the coil of ignition in the following order:
– disconnect electric wires and uncover the coil of ignition 1 (see
fig. 6.17
);
– connect a tester between plugs 1 (–) and 15 (+) and check resistance of primary winding of the coil of ignition;
connect a tester between plugs 4 (HT) and 15 (+) and check resistance of a secondary winding of the coil of ignition.
Control unit
Carry out check of the control unit in the following order:
– disconnect the electric socket from the control unit
(fig. 6.18)
;
– connect a tester to contacts 2 and 4 on the socket of the control unit and include ignition, at the same time the tester has to show accumulator tension;
– switch off ignition and connect the electric socket to the control unit;
– squeeze the fixing uvulas and remove the electric socket from the distributor;
– connect a tester to contacts 1 (–) and 15 (+) on the ignition coil (see
fig. 6.17
.);
– include ignition, at the same time at the first moment tension will make 2 V, and through 1–2 with will decrease to zero. Otherwise replace the control unit;
– disconnect the multioutput electric socket from the Digifant control unit and connect contact 25 to "weight", at the same time tension about 2 V have to increase quickly;
– switch off ignition, connect the multioutput electric socket to the Digifant control unit.
Hall's sensor
Carry out check of the sensor of Hall in the following order:
– squeeze the fixing uvulas and remove the electric socket 8 (see
fig. 6.13
) from the distributor;
– connect a tester to side contacts of the electric socket and include ignition, at the same time the tester has to show tension 10 in (
fig. 6.19
.);
– switch off ignition, connect the electric socket to the distributor;
– disconnect the electric socket from the control unit of system of injection of fuel;
– shift a rubber cover from the electric socket to the distributor, then attach a LED sampler
(fig. 6.20) to the socket of the sensor
;
– include a starter and check that the LED sampler blinks. Otherwise, replace the distributor.
Digifant control unit
Carry out check of the Digifant control unit in the following order:
– full check of the block requires the specialized equipment;
– disconnect the electric socket from the control unit of system of injection of fuel;
– connect a LED sampler to plugs 1 (–) and 15 (+) coils of ignition
(fig. 6.21)
. Connect double contact of the coil of ignition so that only wires were attached to the shielding braid;
– include a starter and check that the LED sampler blinks. Otherwise, replace the control unit.
