Voltage Between; Short Circuit Check (Wire Harness To Ground) - Suzuki Swift User Manual

0A-14 GENERAL INFORMATION
1. Other parts
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.
