Suzuki Swift - Short Circuit Check (Wire Harness to Ground); Voltage between

1. Other parts
1. To other parts
2 V voltage drop
0A-14 GENERAL INFORMATION
If measurements were taken as shown in the figure at the left and
results were as listed below, it means that the circuit is open be-
tween terminals B-1 and A-1.
Voltage Between:
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: 0 V
Also, if measured values were as listed below, it means that there
is a resistance (abnormality) of such level that corresponds to the
voltage drop in the circuit between terminals A-1 and B-1.
Voltage Between:
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: Approx. 3 V
SHORT CIRCUIT CHECK (wire harness to ground)
1) Disconnect negative cable from battery.
2) Disconnect connectors at both ends of the circuit to be checked.
NOTE:
If the circuit to be checked is connected to other parts, dis-
connect all connectors of those parts.
Otherwise, diagnosis will be misled.
3) Measure resistance between terminal at one end of circuit (A-1
terminal in figure) and body ground. If continuity is indicated, it
means that there is a short to ground between terminals A-1 and
C-1 of the circuit.
4) Disconnect the connector included in circuit (connector B) and
measure resistance between A-1 and body ground.
If continuity is indicated, it means that the circuit is shorted to the
ground between terminals A-1 and B-1.
