FI SYSTEM DIAGNOSIS 4-7
• Using continuity inspect or voltage check procedure as
described below, inspect the wire harness terminals for open
circuit and poor connection. Locate abnormality, if any.
A
Looseness of crimping
B
Open
C
Thin wire (a few strands left)
Continuity check
• Measure resistance across coupler
B
(between
A
and
C
in
the figure).
If no continuity is indicated (infinity or over limit), the circuit is
open between terminals
A
and
C
.

• Disconnect the coupler
B
and measure resistance between
couplers
A
and
B
.
If no continuity is indicated, the circuit is open between cou-
plers
A
and
B
. If continuity is indicated, there is an open cir-
cuit between couplers
