Terminal and Connector Inspection
1.

Many malfunctions in the electrical system are caused by poor harness 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?

YES

a.

Repair as necessary and go to "Verification Vehicle Repair" procedure

NO

a.

Go to "W/Harness Inspection" procedure

Signal Circuit Inspection
1.

Check for short to chasis ground in harness

(1)

Ignition "OFF"

(2)

Disconnect ECM connector, leveling actuator,and right/left connector

(3)

Measure resistance between terminal "2" of the ECM (or leveling actuator) harness connector and chasis ground

a.

Specification : Approx. ∞ Ω

(4)

Is the measured resistance within specification?

YES

a.

Go to "Check for short to power circuit in harness" procedure.

NO

a.

Check for short to chasis ground in leveling actuator output harnessRepair as necessary and go to "Verification Vehicle Repair" procedure.

2.

Check for short to power circuit in harness

(1)

Ignition "OFF"

(2)

Disconnect ECM wiring, leveling actuator, right/left connector

(3)

Measure resistance between terminal "2" of the ECM (or leveling actuator) harness connector and terminal "3" of the power supply harness

※ 10.8~11.2V is measured at leveling actuator signal line when ignition "ON" under normal condition

a.

Specification : Approx. ∞ Ω

(4)

Is the measured resistance within specification?

YES

a.

Check the condition of connected part and go to "Verification Vehicle Repair" procedure.

NO

a.

Check for short to power circuit in leveling actuator output harness. Repair as necessary and go to "Verification Vehicle Repair" procedure.
