Open Circuit Test

  1. Procedures for Open Circuit
    • Continuity Check
    • Voltage Check

    If an open circuit occurs (as seen in [Figure below]), 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 the resistance, lightly shake the wire harness vertically or horizontally.

    Specification (Resistance) 

    1Ω or less → Normal Circuit

    1MΩ or Higher → Open Circuit

    1. Disconnect connectors (A) and (C), and measure resistance between connectors (A) and (C) as shown in [Figure below].

      In [Figure below], if the measured resistances in lines 1 and 2 are "over 1MΩ" and "below 1Ω" respectively, line 1 has an open circuit. (Line 2 is normal.) To find the exact broken point, check the sub line of line 1 as described in the next step.

    2. Disconnect connector (B), and measure the resistances between connectors (C) and (B1), and between (B2) and (A) as shown in [Figure below].

      In this case, the measured resistance between connectors (C) and (B1) is higher than 1MΩ and the open circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).

  3. Voltage Check Method
    1. With each connector still connected, measure the voltage between the chassis ground and terminal 1 of each of connectors (A), (B) and (C) as shown in [Figure below].

      The measured voltages of connectors are 5V, 5V and 0V respectively. So the open circuit is between connectors (C) and (B).

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.
