CHECK SHORT CIRCUIT
(a)
If the wire harness is ground shorted as in Fig. 5, locate
the section by conducting a "continuity check with the
body ground".
(b)
Check the continuity with the body ground.
(1)
Disconnect connectors "A" and "C" and measure
the resistance between terminal 1 and 2 of connec-
tor "A" and the body ground.
Resistance: 1 MΩ or higher
HINT:
Measure the resistance while lightly shaking the wire harness
vertically and horizontally.
In the case of Fig. 6:
Between terminal 1 of connector "A" and body
ground
Between terminal 2 of connector "A" and body
ground
Therefore, it is found out that there is a short circuit
between terminal 1 of connector "A" and terminal 1
of connector "C".
(2)
Disconnect connector "B" and measure the resis-
tance between terminal 1 of connector "A" and the
body ground, and terminal 1 of connector "B2" and
the body ground.
In the case of Fig. 7:
Between terminal 1 of connector "A" and body
ground
Between terminal 1 of connector "B2" and body
ground
Therefore, it is found out that there is a short circuit
between terminal 1 of connector "B2" and terminal
1 of connector "C".
