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"
Refer to "Shop Manual" and disconnect LDWS switch connector.
Ignition switch "ON"
Measure the voltage between Pin No. 17 (Power/LHD) terminal of LDWS switch harness connector and chassis ground.
Measure the voltage between Pin No. 14 (Power/RHD) terminal of LDWS switch harness connector and chassis ground.
Specification : B+
Is the measured value within specification?
| ▶ Go to "Ground Circuit Inspection" procedure. |
| ▶ Repair open or short in power circuit and then go to "Verification of vehicle Repair" procedure. |
Ignition switch "OFF"
Refer to "Shop Manual" and disconnect LDWS swtich connector.
Ignition switch "ON"
Measure the voltage between Pin No. 17 (Power/LHD) terminal/Pin No. 14 (Power/RHD) terminal of LDWS swtich harness connector and chassis ground.(A)
Measure the voltage between Pin No. 17 (Power/LHD) terminal/Pin No. 14 (Power/RHD) terminal terminal and Pin No. 2 (Ground/RHD) terminal/Pin No. 9 (Ground/LHD) terminal of LDWS switch harness connector.(B)
Specification : Difference in (A) and (B) is less than 200 mV
Is the measured value within specification?
| ▶ Go to "Component Inspection" procedure. |
| ▶ Repair open or short in ground circuit and then go to "Verification of vehicle Repair" procedure. |
