DTC B2624 Vehicles Speed Malfunction
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.
| DTC Code | Detection Condition | Trouble Area |
| B2624 | The auto away function is disabled with the last vehicle speed signal* at 10 km/h (6 mph) or more.
Vehicle speed signal is lost for 5 seconds or more and the auto away/return function is disabled.
| CAN communication system
Meter/gauge system

| Tester indication is normal | A |
| Tester indication is abnormal | B |
- A vehicle speed of 3 km/h (2 mph) or more may be displayed on the intelligent tester screen immediately after the vehicle comes to a sudden stop. This is caused by a delay in vehicle signal input via the communication bus and is not a malfunction.
