  1. Continuity Check Method
    NOTE: When measuring for resistance, lightly shake the wire harness above and below or from side to side. Specification is (Resistance) 1Ξ© or less --> Normal Circuit 1MΞ© or Higher --> Open Circuit
    1. Disconnect connectors (A) and (C) and measure resistance between connector (A) and (C) as shown in illustration below.

      In illustration below the measured resistance of line 1 is higher than 1MΞ©--> and line 2 is below 1Ξ© -->. 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.

    2. Disconnect connector (B), and measure resistance between connector (C) line 1 and connector (B1) line 1. Measure resistance between (B2) line 1 and (A) line 1 as shown in illustration below.

      In this case the measured resistance between connector (C) and (B1) is higher than 1 MΞ©--> and the open circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).

  2. Voltage Check Method
    1. With each connector still connected, measure the voltage between the chassis ground and terminal 1 of each connector (A), (B) and (C) as shown in illustration.

      The measured voltage of each connector is 5V, 5V and 0V respectively. So the open circuit is between connector (C) and (B).

When to See a Mechanic

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

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