Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damage of component.
Perform checking procedure as follows.
2.1) Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
2.2) Check connecting condition of ECM and component connector : Check terminal separation, damage of locking device and connecting condition between terminal and wiring.
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.)
Is the problem found?
![]() | ▶ Repair the trouble causing part and go to "Verification of Vehicle Repair" procedure. |
![]() | ▶ Go to "Power Circuit Inspection". |
IG key OFF.
Disconnect 'GENERATOR' connector.
IG key ON.
Check voltage between 'LAMP' terminal of 'GENERATOR' harness connector and chassis ground.
Specification : 10.5V ~ 14.5V
Is the measured value within specification?
![]() | ▶ Go to "Check poor connection in 'GENERATOR' B+ cable" as follows. |
![]() | ▶ If no voltage is detected, repair open in charging lamp on cluster, charging lamp resistor and related circuit and go to "Verification of Vehicle Repair". ▶ If the voltage is high than specification value, repair short to battery in charging lamp on cluster, charging lamp resistor and related circuit and go to "Verification of Vehicle Repair". |
IG key OFF
Connect 'GENERATOR' connector.
Engine ON.
Measure voltage between 'BATTERY' terminal of 'GENERATOR' and (+) terminal of battery.
☞ Connect (+) terminal of multimeter to 'BATTERY' terminal of 'GENERATOR' and connect (-) terminal of multimeter to (+) terminal of battery.
Specification : Below 200mV
Is the measured value within specification?
![]() | ▶ Go to "Component Inspection" procedure. |
![]() | ▶ Checking corrosion, deformation of 'GENERATOR' B+ cable. ▶ Replace 'GENERATOR' B+ cable if necessary, and go to "Verification of Vehicle Repair" procedure. |
