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.
