Justy Hatchback 2WD L3-1.2L SOHC (MPFI) (1992)
(F50)1-(F50)2
0.9-1.1 Ohm @ 20° C (68° F)
5.
Measure resistance between coil high tension terminal and connector terminal (F50)1. It should read 10-14K Ohms @ 20° C (68° F).
ECU Connectors
CHECK HARNESS BETWEEN IGNITER AND COIL
1.
Measure resistance between igniter harness connector (F117)4 and coil harness connector (F50)2. It should be below 1 Ohm.
2.
With ECU and igniter disconnected, measure resistance as follows:
Connector & terminal:
Resistance:
(F119)21-(F117)1
Below 1 Ohm
(F120)3-(F117)2
Below 1 Ohm
CHECK ECU HARNESS AND GROUND
1.
Measure resistance between ECU and ground as follows:
Connector & terminal:
Resistance:
(F119)21-Ground
Infinite
(F120)3-Ground
Infinite
2.
With ignition "OFF," disconnect ECU connector.
3.
Measure resistance between ECU and ground as follows:
Connector & terminal:
Resistance:
(F119)1-Ground
Below 10 Ohms
(F120)10-Ground
Below 10 Ohms
CHECK IGNITER OUTPUT SIGNAL
1.
With ignition "ON," measure voltage between ECU connector terminal (F119)21 and ground while engine is being cranked.
2.
Voltage should fluctuate between 1V and 3V.
CHECK IGNITION MONITOR SIGNAL
1.
With ignition "ON," measure voltage between ECU connector terminal (F120)3 and ground while engine is being cranked.
2.
Voltage should fluctuate between 1V and 3V.
