5.
Is the measured voltage within specification?
YES
a.
Go to "Component Inspection" procedure.
NO
a.
Go to "Check open in harness" as follows.
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.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Has a problem been found?
YES
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
▶ Go to " Control Circuit Inspection " procedure.
■ Check voltage
IG "OFF"
Disconnect ETC Motor & TPS connector.
IG "ON" and ENG "OFF"
Measure the voltage between ETC motor(+)/(-) of ETC Motor & TPS harness connector and chassis ground.
Specification : Approx. B+
Is the measured voltage within specification?
YES
Go to "Component Inspection" procedure.
NO
Go to "Check open in harness" as follows.
■ Check open in harness
IG "OFF"
Disconnect ETC Motor & TPS connector and PCM connector.
Measure the resistance between ETC motor (+) terminal of ETC Motor & TPS harness connector and ETC motor (+) terminal of PCM harness connector.
Measure the resistance between ETC motor (-) terminal of ETC Motor & TPS harness connector and ETC motor (-) terminal of PCM harness connector.
Specification : Approx. below 1Ω
Is the measured resistance within specification ?
YES
Go to "Component Inspection" procedure.
NO
Repair Open in motor harness and go to "Verification of Vehicle Repair" procedure.
