Has a problem been found?
 | ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to "Ground Circuit Inspection" procedure. |
Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

Ignition switch "OFF"
Disconnect batter (-) cable.
Refer to "Shop Manual" and disconnect FTS connector.
Measure the resistance between Pin No. 1 (Ground) terminal of FTS harness connector and chassis ground.
Specification : Approx. below 1Ω
Ignition switch "OFF"
Refer to "Shop Manual" and disconnect FTS connector.
Ignition switch "ON"
Measure the voltage between Pin No. 2 (Signal) terminal of FTS harness connector and chassis ground.(A)
Measure the voltage between Pin No. 2 (Signal) terminal and Pin No. 1 (Ground) terminal of FTS harness connector.(B)
Specification : Difference in (A) and (B) is less than 200 mV
Is the measured value within specification?
| ▶ Go to "Signal Circuit Inspection" procedure. |
| ▶ Inspect and repair open or short in circuit, and then go to "Verification of Vehicle Repair" procedure. |
Ignition switch "OFF"
Refer to "Shop Manual" and disconnect FTS connector.
Ignition switch "ON"

Specification : Approx. 5.0V
Is the measured value within specification?
| ▶ Go to "Component Inspection" procedure. |
| ▶ Inspect and repair open or short in circuit, and then go to "Verification of Vehicle Repair" procedure. |
