Power Circuit Inspection

Check voltage of power circuit
1. Key "OFF".
2. Disconnect FTPS connector.
3. Key "ON".
4. Measure the voltage between terminal 1 of FTPS harness connector and chassis ground.
  Specification: Approx. 5V
5. Is the measured voltage within specification ?
  YES
  - Go to "SIGNAL CIRCUIT INSPECTION " procedure.
  NO
  - Go to 2 "Check Open or Short in power circuit inspection" procedure.
Check Open or Short in power circuit inspection
1. Key "OFF".
2. Disconnect FTPS harness connector and ECM/PCM harness connector.
3. Measure the resistance between terminal 1 of FTPS harness connector and terminal 3/C01-2 of ECM/PCM harness connector. (A/T)
  Measure the resistance between terminal 1 of FTPS harness connector and terminal 50/C01 of ECM/PCM harness connector. (M/T)
  
  Specification: Approx. 1Ω
4. Is the measured resistance within specification ?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
