1)
Specification : Refer to " Reference data"
Ignition "OFF" & Engine "OFF".
Disconnect the "OUTPUT SPEED SENSOR" connector
Measure resistance between terminal "1","2" and "2","3" and "1","3" of the "OUTPUT SPEED SENSOR" connector .
Specification : Refer to " Reference data"

[Reference data]
YES
Go to "CHECK PCM/TCM " as below
NO
Replace "OUTPUT SPEED SENSOR" and Go to "Verification Vehicle Repair" procedure
Ignition "ON" & Engine "OFF".
Connect "OUTPUT SPEED SENSOR" connector.
Install scantool and select a SIMU-SCAN,
Simulate frequency to OUTPUT SPEED SENSOR signal circuit.
Is "OUTPUT SPEED SENSOR" signal value changed according to simulation frequency?
YES
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM and then go to "Verification of Vehicle Repair" procedure.
