[O]

: Explains the system outline.

[P]

: Indicates values or explains the function for reference during troubleshooting.

[Q]

: Indicates the reference page showing the position on the vehicle of the parts in the system circuit.

Example : Part ”L4” (Light Failure Sensor) is on page 36 of the manual.

∗

The letter in the code is from the first letter of the part, and the number indicates its order in parts

starting with that letter.

Example : L 4

Parts is 4th in order
Light Failure Sensor

[R]

: Indicates the reference page showing the position on the vehicle of Relay Block Connectors in the system circuit.
