THEFT DETERRENT / KEYLESS ENTRY: SMART ACCESS SYSTEM WITH PUSH-BUTTON START (for Start Function): B2282:
Vehicle Speed Signal Malfunction
B2282 - Vehicle Speed Signal Malfunction

The power management control ECU receives vehicle speed information using 2 methods. It receives a speed signal from the meter ECU. It also
receives speed information from the meter ECU via CAN. If the information sent using these 2 methods is inconsistent, this DTC will be stored.
WIRING DIAGRAM
HINT
* A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter. The signal is changed to a pulse
signal at the transistor in the combination meter. Each ECU controls the respective system based on the pulse signal.
* If a short occurs in an ECU, all systems in the diagram above will not operate normally.
