3. Voltage Check Method
a. With each connector still connected, measure the voltage between the chassis ground and terminal 1 of each connectors (A), (B) and (C) as
shown in [FIG. 4].
The measured voltage of each connector is 5 V, 5 V and 0 V respectively. So the open circuit is between connector (C) and (B).
CHECK SHORT CIRCUIT
4. Test Method for Short to Ground Circuit Continuity Check with Chassis Ground
If short to ground circuit occurs as shown in [FIG. 5], the broken point can be found by performing below Step 2 (Continuity Check Method with
Chassis Ground) as shown below.
5. Continuity Check Method (with Chassis Ground)
NOTE: Lightly shake the wire harness above and below, or from side to side when measuring the resistance.
Specification (Resistance)
1 Ohm or less -> Short to Ground Circuit
1 MOhm or Higher -> Normal Circuit
a. Disconnect connectors (A), (C) and measure for resistance between connector (A) and Chassis Ground as shown in [FIG. 6].
The measured resistance of line 1 and 2 in this example is below 1 Ohm and higher than 1 MOhm respectively. Specifically the short to
ground circuit is line 1 (Line 2 is normal). To find exact broken point, check the sub line of line 1 as described in the following step.
