Precautions for Trouble Diagnosis

CAUTION: Follow the instructions listed below. Failure to do this may cause damage to parts:

• Never apply 7.0 V or more to the measurement terminal.
• Use a tester with open terminal voltage of 7.0 V or less.
• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when checking the harness.

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.
