3.
Has a problem been found?
YES
a.
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
a.
Go to "Power Circuit Inspection" procedure.
Many malfunctions in the electrical system are caused by poor harness(es) 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 then go to "Verification of Vehicle Repair" procedure.
NO
Go to "Power Circuit Inspection" procedure.
Ignition "ON" & Engine "OFF".
Measure voltage between terminal "1" of the G-sensor harness connector and chassis ground.
Specification : Approx. B+
Is the measured voltage within specifications?
YES
Go to "Signal Circuit Inspection" procedure.
NO
Check for open or short in the power harness between battery terminal(+) and terminal "1" of the G-sensor harness connector. Check for open or blown 10A ABS fuse referring to "Circuit Diagram". Repair as necessary and then go to "Verification of vehicle Repair" procedure.
Ignition "OFF".
Disconnect G-sensor connector.
Measure resistance between terminal "3" of the G-sensor harness connector and chassis ground.
Specification : Approx. below 1Ω
Is the measured resistance within specifications?
YES
Go to "Signal Circuit inspection" procedure.
NO
Check for damaged harness and poor connection between terminal "3" of the G-sensor harness connector and terminal "3" of the HECU harness connector. Repair as necessary and then go to "Verification of vehicle Repair" procedure.
Ignition "ON" & Engine "OFF".
Measure voltage between terminal "10" of the HECU harness connector and chassis ground.
Specification : Approx. 2.5V
Is the measured voltage within specifications?
YES
Fault is intermittent caused by open or short G-sensorr and/or faulty G-sensor or was repaired and HECU memory was not cleared. Go to "Component Inspection" procedure.
NO
Check for open or short in the G-sensor harness between terminal "2" of the G-sensor harness connector and terminal "10" of the HECU harness connector. Repair as necessary and then go to "Verification of vehicle Repair" procedure.
