  18. Use the Hioki resistance meter to measure the resistance between the charge port busbar connector lead and the DC input HV header bolt head.
    NOTE: The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ). If the measured resistance is above 0.195 mΩ (195 μΩ), escalate to Service Engineering.
    NOTE: If the resistance is lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again. If after 4 attempts the resistance is consistently lower than 0.050 mΩ (50 μΩ), the test has passed; continue to the next step.
