GENERAL INFORMATION 0A-17
Short circuit check (wire harness to ground)
1) Disconnect negative (–) cable at battery.
2) Disconnect connectors at both ends of the circuit to be
checked.
3) Measure resistance between terminal at one end of circuit
(A-1 terminal in the figure) and body ground. If continuity is
indicated, it means that there is a short to ground between
terminals A-1 and C-1 of the circuit.
4) Disconnect the connector included in circuit (connector B)
and measure resistance between A-1 and body ground.
If continuity is indicated, it means that the circuit is shorted to
the ground between terminals A-1 and B-1.
Intermittent and Poor Connection
Most intermittent are caused by faulty electrical connections or
wiring, although a sticking relay or solenoid can occasionally be at
fault. When checking it for proper connection, perform careful
check of suspect circuits for:
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must be
clean and free of any foreign material which could impede
proper terminal contact. However, cleaning the terminal with
a sand paper or the like is prohibited.
• Damaged connector body, exposing the terminals to mois-
ture and dirt, as well as not maintaining proper terminal ori-
entation with the component or mating connector.
NOTE:
If the circuit to be checked is connected to other parts
(1), disconnect all connectors of those parts.
Otherwise, diagnosis will be misled.
