INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
Revision: 2006 January2006 M35/M45
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.
NG >> Check the following.
10A fuse [No.22, located in the fuse block (J/B)]
Harness for open or short between fuse block and
Intelligent Key unit.
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)
TERMINAL AND REFERENCE VALUE FOR INTELLIGENT KEY UNIT
Standard is the measured voltage between each terminal and ground
