This icon is used on the schematic to link to Control Module References, which identifies which components need programming upon replacement.

Next Schematic Page Icon

This icon is used on the schematic to navigate to the next schematic in the subsystem.

Previous Schematic Page Icon

This icon is used on the schematic to navigate to the previous schematic in the subsystem.

Supplemental Inflatable Restraint (SIR) or Supplemental Restraint System (SRS) Icon

This icon is used to alert the technician that the system contains SIR/SRS components that require certain precautions before servicing.

Information Icon

This icon is used to alert the technician that there is additional information that will aid in servicing a system.

Danger Icon

This icon is intended to alert the technician that a component within the system contains labelling with the same icon.

This icon is used when a source component has potential for 60 volts DC or greater or has potential for 42 volts AC or greater.

High Voltage Icon

This icon is intended to alert the technician that a component within the system contains labelling with the same icon.

This icon is used when a component/circuit has potential for 60 volts DC or greater or has potential for 42 volts AC or greater.

Caution Icon

This icon is used to advise the technician to use caution when servicing this component.

This icon may be used when a component/circuit has a voltage range potential between 30-60 volts DC or 15-42 volts AC.
