■ Check open in harness 

1. IG "OFF" and disconnect ECTS connector and then IG "ON".
2. Measure voltage between TPS power terminal of ETC Motor & TPS harness connector and chassis ground.(Measurement "A")
3. Measure voltage between TPS power and TPS ground terminals of ETC Motor & TPS harness connector.(Measurement "B")

   Specification:  Voltage difference between measurement "A" and "B" is below 200mV.
