Vehicle Speed Signal Circuit Between Navigation Receiver Assembly and Combination Meter
Vehicle Speed Signal Circuit between Navigation Receiver Assembly and Combination MeterDESCRIPTION
The navigation receiver assembly receives a vehicle speed signal from the combination meter and information about the GPS antenna, and then adjusts vehicle position.
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.
