Speedometer Malfunction: Description
- The meter CPU receives vehicle speed signals from this circuit.
- The vehicle speed sensor detects the voltage that varies according to the vehicle speed.
- The skid control ECU supplies power to the vehicle speed sensor.
- The skid control ECU detects vehicle speed signals based on the pulses of the voltage.
- The skid control ECU transmits vehicle speed signals as pulses to the meter CPU.
- The meter CPU calculates the vehicle speed converting 4 pulses to 1 revolution
