B2624
Diagnostic trouble codes
DESCRIPTION
The multiplex tilt & telescopic ECU forms a network with the ECUs of other systems through the communication bus. Each ECU informs the other ECUs that they are connected to the network by outputting a specified signal (periodic signal) onto the communication bus on a regular basis. The multiplex tilt & 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.| DTC No. |
