READ VALUE USING INTELLIGENT TESTER (VEHICLE SPEED)
CHECK DTC (MALFUNCTION IN CAN COMMUNICATION SYSTEM WITH ECM)
DTC B2059 Vehicle Speed Malfunction
DESCRIPTION
The seat belt control ECU receives vehicle speed information from the ECM and master cylinder solenoid (skid control ECU) via CAN communication.
The ECM receives vehicle speed information from the master cylinder solenoid (skid control ECU) through the combination meter.
This DTC is stored when there is a difference in the vehicle speed information from the ECM and master cylinder solenoid (skid control ECU).
DTC Code | DTC Detection Condition | Trouble Area |
B2059 | The vehicle speed information from the ECM and the vehicle speed information from the master cylinder solenoid (skid control ECU) are different. | Combination meter ECM Master cylinder solenoid (skid control ECU) Seat belt control ECU Distance control ECU |
