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

DTC B2563 HI VOLTAGENIS001YZ
DIAGNOSIS DESCRIPTION
B2563 battery high voltage monitors the battery voltage input to Intelligent Key unit. When the condition that
the voltage is 18V or more is detected for 90 seconds or more, it judges that it is the malfunction and displays
the DTC (Diagnostic Trouble Code)
