5-8 FI SYSTEM
SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND)
• Disconnect the negative cable from the battery.
• Disconnect the connectors/couplers at both ends of the circuit
to be checked.
NOTE:
If the circuit to be checked branches to other parts as shown,
disconnect all connectors/couplers of those parts. Otherwise,
diagnosis will be misled.
• Measure resistance between terminal at one end of circuit (A
terminal in figure) and body ground. If continuity is indicated,
there is a short circuit to ground between terminals A and C.
• Disconnect the connector/coupler included in circuit (coupler
B) and measure resistance between terminal A and body
ground.
If continuity is indicated, the circuit is shorted to the ground
between terminals A and B.
