DTC B2282: Vehicle Speed Signal Malfunction; DTC B2283: Vehicle Speed Sensor Malfunction: Description

WARNING: This page is about a different car, the 2012 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

The skid control ECU converts these signals into 4-pulse signals and sends them to the combination meter. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the main body ECU (instrument panel junction block). The main body ECU (instrument panel junction block) determines the vehicle speed based on the frequency of these pulse signals.

The main body ECU (instrument panel junction block) and the combination meter are connected by a cable and the CAN. DTC B2282 is output when the cable information and CAN information are inconsistent.

HINT:

When the main body ECU (instrument panel junction block) is replaced with a new one and the cable from the negative (-) battery terminal is connected, the power source mode becomes the IG-ON mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.

After the main body ECU (instrument panel junction block) is replaced, perform the registration procedures for the engine immobilizer system. Refer to REGISTRATION .
