5.
Is the measured voltage within specification?
YES
a.
Go to "Component Inspection" procedure.
NO
a.
Go to "Check short in harness" as follows.
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 connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Has a problem been found?
YES
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
▶ Go to "Signal Circuit Inspection" procedure.
■ Check voltage
IG "OFF" and disconnect CKPS connector.
IG "ON" and ENG "OFF"
Measure voltage between low signal terminal of CKPS harness connector and chassis ground.
