Precautions For Harness Repair

Precautions for Harness Repair




- Solder the repaired area and wrap tape around the soldered area.

NOTE: A fray of twisted lines must be within 110 mm (4.33 in).




- Bypass connection is never allowed at the repaired area.

NOTE: Bypass connection may cause CAN communication error. The spliced wire becomes separated and the characteristics of twisted line are lost.

- Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communication line.
