B2557 VEHICLE SPEED

Description

INFOID:0000000005515524

BCM receives the 2 vehicle speed signals via CAN communication. 1 signal is transmitted by the combination
meter. Another signal is transmitted by “ABS actuator and electric unit (control unit)”. BCM compares both sig-
nals to detect the vehicle speed.
