DTC B2558 SHIFT POSITIONNIS001YV
DIAGNOSIS DESCRIPTION
B2558 shift position input system monitors the A/T selector lever position. If there is the difference between
the input from A/T device, the input from A/T assembly, and CAN communication input from A/T control unit, it
judges that it is the malfunction and displays the DTC (Diagnostic Trouble Code)
TERMINALS AND REFERENCE VALUE FOR INTELLIGENT KEY UNIT

2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Check voltage between Intelligent Key unit connector and ground.
OK or NG
OK >> Check the condition of harness and connector. If it is
OK, check the self-diagnosis results using CONSULT-II
again.
