System Wiring Diagram
Operation
• The air charging pressure signal from the PCM via CAN lines is input to the microcomputer in the instrument cluster. The microcomputer outputs a control signal to the boost gauge based on the air charging pressure signal.
Boost Gauge Control
• The instrument cluster switches the boost gauge display based on the air charging pressure signal input from the PCM.
• The boost gauge has 13 display patterns that are switched according to the air charging pressure.
• When the air charging pressure value sent from the PCM is between -100 — -41, or it is abnormal, the boost gauge is not displayed.
