B2624 LEXUS Description
The Multiplex Tilt and Telescopic ECU forms a network with the ECUs of other systems through the communication bus. Each ECU informs the other ECUs that it is connected to the network by outputting a specified signal (periodic signal) to the communication bus on a regular schedule. The Multiplex Tilt and Telescopic ECU receives vehicle speed signals from the combination meter via the communication bus to prevent improper operation of the auto away/return function during driving. The Diagnostic Trouble Code (DTC) sets when the auto away function is disabled with the last vehicle speed signal* at 10 km/h (6 mph) or more or the vehicle speed signal is lost for 5 seconds or more and the auto away/return function is disabled.
