Signal Circuit Inspection

■ Check voltage 

1. IG "OFF". Disconnect ETC Motor & TPS connector.
2. IG "ON".
3. Measure voltage between TPS1 signal terminal of ETC Motor & TPS harness connector and chassis ground.

   Specification:  Approx. 5V

4. Is the measured voltage within specification?

   YES 

   • Go to "Check open in harness" as follows.

   NO 

   • Go to "Check short to battery in harness" below.

■ Check open in harness 

1. IG "OFF". Disconnect ETC Motor & TPS connector and PCM connector.
2. Measure resistance between TPS1 signal terminal of ETC Motor & TPS harness connector and TPS1 signal terminal of PCM harness connector.

   Specification:  Below 1Ω

3. Is the measured resistance within specification?

   YES 

   • Go to "GROUND CIRCUIT INSPECTION " procedure.

   NO 

   • Repair open in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check short to battery in harness 

1. IG "OFF". Disconnect ETC Motor & TPS connector and PCM connector.
2. Measure resistance between TPS1 signal and TPS power terminals of ETC Motor & TPS harness connector. (Measurement "A")
3. Measure resistance between TPS1 signal and ETC motor (+) terminals of ETC Motor & TPS harness connector. (Measurement "B")
4. Measure resistance between TPS1 signal and ETC motor (-) terminals of ETC Motor & TPS harness connector. (Measurement "B")

   Specification:  Infinite

5. Is the measured resistance within specification?

   YES 

   • Go to "GROUND CIRCUIT INSPECTION " procedure.

   NO 

   • Repair short to battery in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
