The skid control ECU converts signals from the speed sensor into 4-pulse signals and sends them to the combination meter. After these signals are converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, they are then transmitted to the power management control ECU. The power management control ECU determines the vehicle speed based on the frequencies of these pulse signals.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2283 | Both conditions are met: The vehicle speed decreases significantly. The vehicle speed does not correspond with the engine speed. | Power management control ECU Meter/gauge system Skid control ECU Speed sensor Harness or connector |

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 its respective system based on the pulse signal.
- If a short circuit occurs in an ECU, all systems related to the components in the diagram above will not operate normally.

The push-button start function uses a push-type engine switch, which the driver can operate by merely carrying the key. This system consists primarily of the power management control ECU, engine switch, ID code box, steering lock ECU, key, ACC relay, IG1 relay, IG2 relay and certification ECU. The power management control ECU controls the system. This function operates in cooperation with the smart key system.
When the engine switch is pushed with the key in the cabin, the power management control receives signals to switch the power source mode.

HINT
To allow use of the Techstream to inspect the push-button start function when the engine switch is off, repeatedly open and close any of the doors. Repeatedly opening and closing a door establishes communication between the Techstream and power management control ECU (opening and closing a door can also be simulated by operating a door courtesy light switch).
