W/Harness Inspection





Ground Circuit inspection

1. Ignition "OFF"
2. Disconnect FLS connector
3. Measure resistance between terminal 3 of the FLS harness connector and chassis ground
A. Specification: Approx. 0 Ohm




4. Is resistance within the specification ?
YES
1) Go to next step as below.
NO
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure

Signal Circuit Inspection

Check for short to Power in signal circuit
1. Ignition "ON" & Engine "OFF"
2. Measure voltage between terminal 2 of the FLS harness connector and chassis ground
A. Specification: Approx. 0V




3. Is voltage within the specification ?
YES
1) Go to next step as below.
NO
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure
Check for open in signal circuit (Between FLS connector and ECM connector)
1. Disconnect ECM connector
2. Measure resistance between terminals 2 of the FLS harness connector and 36 of the ECM harness connector.
A. Specification: Approx. 0 Ohm


3. Is resistance within the specification ?
YES
1) Go to next step as below.
NO
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure

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
1) Go to Component Inspection
