2. Disconnect FTPS connector
3. Ignition "ON" & Engine "OFF"
4. Measure voltage between terminal 1 of the FTPS harness connector and chassis ground
A. Specification: Approx. 5V




5. Is voltage within the specification ?
YES

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found ?
YES
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
