If an open circuit occurs (as seen in [FIG. 1]), it can be found by performing Step 2 (Continuity Check Method) or Step 3 (Voltage Check
Method) as shown below.
2. Continuity Check Method
NOTE: When measuring for resistance, lightly shake the wire harness above and below or from side to side.
Specification (Resistance)
1 ohm or less -> Normal Circuit
1 Mohm or Higher -> Open Circuit
a. Disconnect connectors (A), (C) and measure resistance between connector (A) and (C) as shown in [FIG. 2].
In [FIG.2.] the measured resistance of line 1 and 2 is higher than 1 Mohm and below 1 ohm respectively. Specifically the open circuit is
line 1 (Line 2 is normal). To find exact break point, check sub line of line 1 as described in next step.
b. Disconnect connector (B), and measure for resistance between connector (C) and (B1) and between (B2) and (A) as shown in [FIG. 3].
In this case the measured resistance between connector (C) and (B1) is higher than 1 Mohm and the open circuit is between terminal 1 of
connector (C) and terminal 1 of connector (B1).
