DTC B2554 ACC POWER CIRCUITNIS001YR
DIAGNOSIS DESCRIPTION
B2554 ACC power supply circuit monitors the following 2 signals.
Though the power supply switching control to ACC position by push-button ignition switch operation is
performed normally, if there is no ACC power supply input to the Intelligent Key unit, it judges that it is the
malfunction and displays the DTC (Diagnostic Trouble Code)
When performing the power supply switching control to ACC position by push-button ignition switch oper-
ation, if the power supply position switching cannot be performed because the wake-up signal is not
entered into PDU (Power Distribution Unit), it judges that it is the malfunction and displays the DTC (Diag-
nostic Trouble Code)

DTC B2557 VEHICLE SPEEDNIS001YU
DIAGNOSIS DESCRIPTION
B2557 vehicle speed signal compares the vehicle speed input from the unified meter and A/C amp. and ABS
via CAN communication and the vehicle signal (8 pulses) from the unified meter and A/C amp. If there is the
difference between each vehicle speed input, it judges that it is the malfunction and displays the DTC (Diag-
nostic Trouble Code).
