Check Short Circuit

2005 Hyundai Santa Fe GLS, 2.7 D, AWDSECTION 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 Fig 1, the broken point can be found by performing next step .

  2. 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)

    1Ω or less --> Short to Ground Circuit

    1MΩ or Higher --> Normal Circuit

    1. Disconnect connectors (A), (C) and measure for resistance between connector (A) and Chassis Ground as shown in Fig 2.

      The measured resistance of line 1 and 2 in this example is below 1 Ω and higher than 1MΩ 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 next step .

    2. Disconnect connector (B), and measure the resistance between connector (A) and chassis ground, and between (B1) and chassis ground as shown in Fig 3.

      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).

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
