DTC B2282 Vehicle Speed Signal Malfunction
DTC B2283 Vehicle Speed Sensor Malfunction
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: Vehicle speed decreases significantly. Vehicle speed does not correspond with engine speed. | Main body ECU Combination meter assembly Speed sensor Skid control ECU Harness or connector |

INSPECTION PROCEDURE
| 1.READ VALUE USING INTELLIGENT TESTER (VEHICLE SPEED SIGNAL) |
Use the Data List to check if the vehicle speed signal is functioning properly.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| Vehicle Speed Signal | Vehicle speed signal/STOP or RUN | STOP: Vehicle stopped RUN: Vehicle running | - |
| Result | Proceed to |
| Display on the intelligent tester does not change according to vehicle condition | A |
| Display on the intelligent tester changes according to vehicle condition | B |
|

| A | |
| 2.CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - COMBINATION METER) |
Disconnect the E3 main body ECU connector.
Disconnect the E7 combination meter connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition E3-9 (SPD) - E7-4 (+S) Always Below 1 Ω E3-9 (SPD) or E7-4 (+S) - Body ground Always 10 kΩ or higher
|
| ||||
| OK | |
| 3.REPLACE MAIN BODY ECU |
Temporarily replace the main body ECU with a new or normally functioning one.
Check whether DTC B2282 and B2283 are output.
| Result | Proceed to |
| DTC not output | A |
| DTC output (w/ Multi-information Display) | B |
| DTC output (w/o Multi-information Display) | C |
