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.
