Precautions for Trouble Diagnosis

CAUTION: • 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.
