DTC B2282: Vehicle Speed Signal Malfunction; DTC B2283: Vehicle Speed Sensor Malfunction (08/2011 - ): Description

The main body ECU and the combination meter are connected with a cable and the CAN communication line. DTC B2282 is stored when signals, transmitted through the cable and communication line, do not match.

DTC Code Detection Condition Trouble Area
B2282 When the following conditions are met:
  • Signals between the main body ECU and combination meter are inconsistent.
  • A malfunction is detected in the circuit between the vehicle speed sensor and combination meter.
  • Main body ECU
  • Combination meter assembly
  • Harness or connector

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 main body ECU. The main body ECU determines the vehicle speed based on the frequencies of these pulse signals.

DTC Code Detection Condition Trouble Area
B2283 When both of the conditions below are met:
  • The vehicle speed decreases significantly.
  • The vehicle speed does not correspond with the engine speed.
  • Main body ECU
  • Combination meter assembly
  • Speed sensor
  • Skid control ECU
  • Harness or connector
