Precautions for Trouble Diagnosis

INFOID:0000000009269332

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

INFOID:0000000009269333

• 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 communica-

tion line.
