●

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 communi-
cation line.
