Terminal and Connector Inspection

1.

Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems 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

a.

Repair the trouble causing part and go to "Verification of Vehicle Repair".

NO

a.

Go to "Power Circuit Inspection".

Power Supply Circuit Inspection

1.

Check power circuit voltage

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnector APTS connector, VSCA connector, DPS connector and ECTS connector.

(3)

IG KEY "ON".

(4)

Measure the voltage of APTS connector terminal 3, VSCA connector terminal 3, DPS connector terminal 1 and ECTS terminal 1.

1)

Specification : 4.8V~5.1V

(5)

Is the measured voltage within the specification?

YES

a.

Go to "Component Inspection".

NO

a.

Go to "2. Check short to ground in power circuit" as follows.

2.

Check short to ground in power circuit

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnector APTS connector, VSCA connector, DPS connector, ECTS connector and ECM connectors.

(3)

IG KEY "ON"

(4)

Measure the voltage of APTS connector terminal 3, VSCA connector terminal 3, DPS connector terminal 1 and ECTS terminal 1.

1)

Specification : 0.0V~0.1V

(5)

Is the measured resistance within the specification?

YES

a.

Repair short to battery and go to "Verification of Vehicle Repair".

NO

a.

If the circuit is insulated well and the sensor power supply from ECM is high, replace ECM and go to "Verification of Vehicle Repair".
