1. IG "OFF". 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.

4. Is the measured voltage within specification?
