4. Is the measured voltage within specification ?
▶ Go to "Signal circuit inspection" procedure.
▶ Repair open or short to ground in power harness, and go to "Verification of Vehicle Repair"
procedure.
Signal Circuit Inspection
■ Check short to ground in harness
1. IG "OFF" and disconnect ETC Motor & TPS connector and ECM connector.
2. Measure resistance between TPS2 signal terminal of ETC Motor & TPS harness connector and chassis
ground.(Measurement "A")
3. Measure resistance between TPS2 signal and TPS ground terminals of ETC Motor & TPS harness
connector.(Measurement "B")
Specification : Infinite
4. Is the measured resistance within specification ?
▶ Go to "Check open in harness" as follows.
▶ Repair short to ground in harness and go to "Verification of Vehicle Repair" procedure.
■ Check open in harness
1. IG "OFF" and disconnect ETC Motor & TPS connector and ECM connector.
2. Measure resistance between TPS2 signal terminal of ETC Motor & TPS harness connector and TPS2 signal terminal
of ECM harness connector.
Specification : Below 1Ω
3. Is the measured resistance within specification ?

Component Inspection
■ Check TPS resistance
1. IG "OFF" and disconnect ETC Motor & TPS connector.
2. Measure resistance between TPS power and TPS ground terminals of ETC Motor & TPS connector.(component
side)
Specification : 1.6 ~ 2.4kΩ
3. Is the measured resistance within specification ?
▶ Substitute with a known - good ECM and check for proper operation. If the problem is
corrected,
