Short Circuit Check (Wire Harness to Ground)

Disconnect negative (-) cable at battery.
Disconnect connectors at both ends of the circuit to be checked.
NOTE: If the circuit to be checked is connected to other parts (1), disconnect all connections to these parts.
This is essential to having correct check results.
Measure resistance between the terminal at one end of the circuit ("A-1" terminal in the figure) and ground. If continuity is indicated, it means that the circuit is shorted to ground between terminals "A-1" and "C-1".

Disconnect the connector included in circuit (connector-B) and measure resistance between "A-1" and ground. If continuity is indicated, the circuit is shorted to ground between terminals "A-1" and "B-1".
