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 ?






EMC Signal Inspection

1. Ignition ON, Engine : ON.
2. TCCU, EMC connector : Connect.
3. Monitor signal waveform between terminal 1 of EMC harness connector and chassis ground.
4. Shift to N Range.

Specification : Signal Waveform & Data






CAUTION:
The above value is only for reference.
The actual value may differ from it according to various engine condition.


5. Is EMC Signal display near the specified value ?






EMC wiring battery short Inspection

1. IG "OFF" & ENG "OFF"
2. Electric Magnet Valve Clutch,TCCU connector : Disconnect.
3. IG "ON".
4. Measure voltage between terminal 1 of EMC harness connector and chassis ground.

Specification : 0V






CAUTION:
The above value is only for reference.
The actual value may differ from it according to various engine condition.


5. Is voltage display near the specified value ?






EMC harness open Inspection

1. IG "OFF" & ENG "OFF"
2. Electric Magnet Valve Clutch, TCCU connector : Disconnect.
3. Measure resistance between terminal 1 or 2 of Electric Magnet Valve Clutch harness connector and terminal 26 or 13 of TCCU harness connector.

Specification : 1 ohms below.






CAUTION:
The above value is only for reference.
