Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Ignition system>> Check of system of ignition>> Check of system of ignition ТС1
Ignition coil
Check of the coil of ignition is carried out in the following order:

Fig. 6.17. Check of resistance of a secondary winding of the coil of ignition: 1–ignition coil; 2–the plug of ignition 1 (–); 3–plug 4 (NT); 4–plug 15 (+)


– disconnect electric wires and uncover the ignition coil (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 (NT) and 15 (+) and check resistance of a secondary winding of the coil of ignition.

Control unit
Check of the control unit ТС1 carry out in the following order:
– remove a water-proof protective cover from the control unit;
– compress fixing uvulas and disconnect the electric socket from the control unit;
– connect a tester to contacts 2 and 4 on the control unit socket;
– include ignition, thus the voltmeter should show tension of the accumulator. Otherwise check electric wires;
– switch off ignition, disconnect a tester and repeatedly connect the socket;

Fig. 6.12. Distributor of ignition of system ТС1: 1–distributor rotor; 2–dustproof cap; 3–lock ring; 4–pin; 5–the steel screen with cuts; 6–spring washer; 7–washer; 8–spring bracket; 9–electric socket; 10-screw; 11-nest of the electric socket; 12-Hall sensor; 13-washer; 14-basic plate; 15-distributor case; 16-vacuum regulator of an advancing of ignition; 17-bolt; 18-holder; 19-sealing ring


– compress fixing uvulas and disconnect the electric socket 9 (see fig. 6.12 ) from the ignition distributor;
– connect a tester to contacts 1 (–) and 15 (+) on the ignition coil (see fig. 6.17 );
– include ignition, thus during the first moment tension will make 2 In, and through 1–2 with will decrease to zero. Otherwise replace the control unit;
– connect the central contact of a wire of the distributor to "weight", thus during the first moment tension will make 2 Century. Otherwise check the central wire or replace the control unit;
switch off ignition;
connect a tester between external contacts of a wire of the distributor;
include ignition, the tester should show 5 In;
disconnect a tester and connect the electric socket to the distributor.

Hall sensor
Check of the sensor of the Hall carry out in the following order:
– disconnect high-voltage wires from a cover of the distributor and connect it to weight;
– remove a water-proof protective cover from the control unit;

Fig. 6.22. Check of the sensor of the Hall


– connect a tester to contacts 6 and 3 on the control unit socket, leaving the socket connected to the block (fig. 6.22) ;
– include ignition;
– a wrench for a bolt of fastening of a pulley, slowly turn a cranked shaft of the engine clockwise, supervising tester indications. Tension should change in steps between zero and 2 Century. Otherwise replace the Hall sensor.
