Inspection/Repair - W/Harness Inspection

Terminal & Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal conditions. 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?






CAN communication line inspection

Check short to battery or short to ground in CAN communication line.
1. IG "ON" & ENG "OFF"
2. After connect GDS, select "Oscilloscope" mode.
3. Measure signal waveform of CAN-High terminal of Data Link Connector and chassis ground.
4. Measure signal waveform of CAN-Low terminal of Data Link Connector and chassis ground.

Specification : Refer to "Signal Waveform"









5. Is the measured signal waveform normal ?





Check open in CAN communication line
1. IG KEY OFF.
2. Disconnect TCCM, ESC Module connector.
3. Measure resistance between communication line terminal of TCCM connector and communication line of ESC Module harness connector.

Specification : About below 1 Ohm









4. Is the measured value within specification ?
