• 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 communica-

tion line.
