Speedometer Malfunction

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 ABS & traction actuator assembly supplies power to the vehicle speed sensor.
- The ABS & traction actuator assembly detects vehicle speed signals based on the pulses of the voltage.
- The ABS & traction actuator assembly transmits vehicle speed signals as pulses to the meter CPU.
- The meter CPU calculates the vehicle speed converting 4 pulses to 1 revolution.

HINT: If the vehicle has a VDIM function, the skid control ECU is built into the ABS & traction actuator assembly.
