4.
Is the measured resistance within specification ?
YES
a.
Go to "Check open in harness" as follows.
NO
a.
Repair or replace as necessary and then, go to "Verification of Vehicle Repair" 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 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 "Power Circuit Inspection " procedure.
■ Check voltage
IG "OFF" and disconnect APS connector.
