W/Harness Inspection

Terminal and Connector Inspection

1. 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.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
3. Has a problem been found?
YES
1) Repair as necessary and go to "verification of vehicle repair" procedure
NO
1) Go to "Signal Circuit Inspection" procedure

Signal Circuit Inspection

Check "OUTPUT SPEED SENSOR SIGNAL CIRCUIT 1"
1. Ignition "ON" & Engine "OFF".
2. Disconnect the "C106-1" connector
3. Measure voltage between terminal "10" of the C106-1 harness connector and chassis ground.
A. Specification : approx. 5V




4. Is voltage within specifications?
YES
1) Go to "OUTPUT SPEED SENSOR SIGNAL CIRCUIT 2" as below
NO
1) Check for open or short in harness. Repair as necessary and Go to "verification of vehicle repair" procedure
2) If signal circuit in harness is OK, Go to "Component Inspection" procedure.
Check "OUTPUT SPEED SENSOR SIGNAL CIRCUIT 2"
1. Remove "OIL PAN"
2. Connect the "C106-1" connector
3. Ignition "ON" & Engine "OFF".
4. Disconnect the "OUTPUT SPEED SENSOR" connector
5. Measure voltage between terminal "WHITE COLOR" of the OUTPUT SPEED SENSOR harness connector and chassis ground.
A. Specification : approx. 5V








6. Is voltage within specifications?
YES
1) Go to "Power circuit Inspection" procedure
NO
1) Check for open or short in harness (C06-1 ~ TRANSMISSION RANGE SWITCH). Repair as necessary and Go to "verification of vehicle repair" procedure
2) If signal circuit in harness is OK, Replace "TRANSMISSION RANGE SWITCH" as necessary and Go to "verification of vehicle repair" procedure

Power Supply Circuit Inspection

1. Remove "OIL PAN"
2. Connect the "C06-1" connector
3. Ignition "ON" Engine "OFF".
4. Disconnect the "OUTPUT SPEED SENSOR" connector
5. Measure voltage between terminal "PINK COLOR" of the OUTPUT SPEED SENSOR harness connector and chassis ground.
A. Specification : approx. 12V








6. Is voltage within specifications?
YES
1) Go to "Ground circuit Inspection" procedure
NO
1) Replace "TRANSMISSION RANGE SWITCH" as necessary and Go to "verification of vehicle repair" procedure

Ground Circuit inspection

1. Ignition "OFF" & Engine "OFF".
2. Remove "OIL PAN"
3. Connect the "C06-1" connector
4. Disconnect the "OUTPUT SPEED SENSOR" connector
5. Measure resistance between terminal "BLACK COLOR" of the OUTPUT SPEED SENSOR harness connector and chassis ground.
A. Specification : approx. 0 Ohm








6. Is resistance within specifications?
YES
1) Substitute with a known-good "OUTPUT SPEED SENSOR" and check for proper operation. If the problem is corrected, replace "OUTPUT SPEED SENSOR" as necessary and go to "verification of vehicle repair" procedure.
NO
1) Replace "TRANSMISSION RANGE SWITCH" as necessary and Go to "verification of vehicle repair" procedure
