Speed Signal Circuit (Multi-Display-Combination Meter Assy)
SPEED SIGNAL CIRCUIT (MULTI-DISPLAY - COMBINATION METER ASSY)CIRCUIT DESCRIPTION
The multi-display performs switch operation control during driving by receiving a vehicle speed signal from the combination meter assy.
HINT:
- A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter. The signal is changed to a pulse signal at the transistor in the combination meter. Each ECU controls the respective system based on the pulse signal.
- If a short occurs in an ECU, all systems in the diagram will not operate normally.
