Terminal and Connector Inspection
1.

Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

3.

Has a problem been found?

▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.

▶ Go to "Control Circuit Inspection" procedure.

Control Circuit Inspection
■ Check motor control circuit
1.

Ignition Switch "OFF"

2.

Refer to "Shop Manual" and disconnect the VSA connector.

3.

Ignition Switch "ON"

4.

Measure voltage of Pin No. 1(motor +) of the VSA connector and chassis ground.

5.

Measure voltage of Pin No. 2(motor -) of the VSA connector and chassis ground.

Specification : B+

6.

Ignition Switch "OFF"

7.

Disconnect battery (-) cable.

8.

Refer to "Shop Manual" and disconnect the VSA connector.

9.

Measure voltage between Pin No. 1(motor +) of the VSA and chassis ground.

10.

Measure voltage between Pin No. 2(motor -) of the VSA and chassis ground.

Specification : Approx. 0V

11.

Ignition Switch "OFF"

12.

Disconnect battery (-) cable.

13.

Refer to "Shop Manual" and disconnect the VSA connector.

14.

Measure resistance between Pin No. 1(motor +) and Pin No. 2(motor -) of the VSA.

Specification : ∞ Ω

15.

Is the measured value within specification?

▶ Go to "Component Inspection" procedure.

▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
