POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM, Diagnostic DTC:B2624

DTC Code DTC Name
B2624 Vehicles Speed Malfunction

DESCRIPTION

The multiplex tilt and telescopic ECU forms a network with the ECUs of other systems via CAN communication. Each ECU informs the other ECUs that it is connected to the network by sending 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 assembly via the CAN communication bus to prevent improper operation of the auto away/return function while driving.

      Tech Tips

      A vehicle speed of 3 km/h (2 mph) or more may be displayed on the GTS immediately after the vehicle comes to a sudden stop. This is caused by a delay in vehicle signal received via CAN communication and is not a malfunction.
