Check Short Circuit

1. Test Method for Short to Ground Circuit
   • Continuity Check with Chassis Ground

   If short to ground circuit occurs as shown in [Figure below], the broken point can be found by performing Step 2 (Continuity Check Method with Chassis Ground) as shown below.

2. Continuity Check Method (with Chassis Ground)

Specification (Resistance) 

1Ω or less → Short to Ground Circuit

1MΩ or Higher → Normal Circuit

1. Disconnect connectors (A) and (C) and measure the resistance between connector (A) and Chassis Ground as shown in [Figure below].

   The measured resistance is below 1 Ω for line 1 and higher than 1 MΩ for line 2. Specifically, the short to ground circuit is in line 1. (Line 2 is normal.) To find exact broken point, check the sub line of line 1 as described in the following step.

2. Disconnect connector (B), and measure the resistance between connector (A) and chassis ground, and between (B1) and chassis ground as shown in [Figure below].

The measured resistance between connector (B1) and chassis ground is 1Ω or less. The short to ground circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).
