TERMINAL AND CONNECTOR INSPECTION
E0B082ED
1.
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.
2.
Perform checking procedure as follows.
1)
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
2)
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.
NOTE
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for
checking connecting condition. ( after checking, reconnect the pin at correct position. )
3.
Is the problem found?
YES
▶
Repair the trouble causing part and go to "Verification of Vehicle Repair".
NO
▶
Go to "Power Circuit Inspection".
POWER CIRCUIT INSPECTION
E6CF3DDE
1.
Check power circuit voltage
1)
IG KEY "OFF", ENGINE "OFF".
2)
Disconnect main relay.
3)
Measure the voltage of main relay terminal 2 and 5.

FUEL SYSTEM
Specification : 11.5V~13.0V
4)
Is the measured voltage within the specification?
YES
▶
Go to "Check power supply line(relay
→
actuator)" as follows.
NO
▶
Repair E/R FUSE
&
RELAY BOX 40A ECU MAIN FUSIBLE LINK and related circuit and go to "Verification
of Vehicle Repair".
2.
Check power supply line(relay
→
actuator)
1)
IG KEY "OFF", ENGINE "OFF".
2)
