B2624 - Vehicles Speed Malfunction

DESCRIPTION

The multiplex tilt and telescopic ECU forms a network with the ECUs of other systems through the CAN communication bus. Each ECU informs the

other ECUs that it is connected to the network by outputting a specified signal (periodic signal) onto the communication bus on a regular basis. The

multiplex tilt and telescopic ECU receives vehicle speed signals from the combination meter via the CAN communication bus to prevent improper

operation of the auto away/return function during driving.
