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 short to battery in harness
IG "OFF".
Disconnect APS and PCM connector.
Measure resistance between terminal 1 and 3 of APS harness connector.
Measure resistance between terminal 3 and 4 of APS harness connector.
Specification : Infinite
Is the measured reisistance within specification ?
YES
▶ Go to "Ground Circuit Inpsection" procedure.
NO
▶ Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
Check open in harness
IG "OFF"
Disconnect APS connector.
Measure voltage between terminal 3 of APS harness connector and chassis ground.(Fig. A)
Measure voltage between terminal 3 and 6 of APS harness connector.(Fig. B)
Specification : Fig."A" - Fig. "B" = Approx. below 200mV
Is the measured voltage within specification ?
YES
▶ Go to "Component Inspection" procedure.
NO
▶ Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.
