DTC B2562 LOW VOLTAGENIS001YY
DIAGNOSIS DESCRIPTION
B2562 battery low voltage monitors the battery voltage input to Intelligent Key unit. When the condition that the
voltage is 8.8V or less is detected for 1.5 seconds or more, it judges that it is the malfunction and displays the
DTC (Diagnostic Trouble Code)
TERMINALS AND REFERENCE VALUE FOR INTELLIGENT KEY UNIT
Standard is the measured voltage between each terminal and ground
SELF-DIAGNOSTIC LOGIC
DIAGNOSTIC PROCEDURE
1. CHECK BATTERY
Measure the battery output voltage. Make sure that it is 9V or more.
OK or NG
OK >> GO TO 2.
NG >> Charge or replace the battery.

through 10A fuse [No.21, located in the fuse block (J/B)]

to BCM terminal 42.
Ground is supplied

to BCM terminal 52

through body grounds M16 and M70.
When trunk lid opener cancel switch is ON and trunk lid opener switch is ON (pushed)
Ground is supplied

to BCM terminal 30

through trunk lid opener switch terminals 1and 2

through trunk lid opener cancel switch terminals 1and 3 and

through body grounds M16 and M70.
And power is supplied

through BCM terminal 68

to trunk lid opener actuator terminal 3.
Ground is supplied

to trunk lid opener actuator terminal 2

through body grounds B402,B405.
Then BCM open trunk lid opener actuator.
TRUNK LID OPENER OPERATION
When trunk lid opener switch or trunk button of Intelligent Key is ON, BCM opens trunk opener actuator.
BCM can open trunk lid opener actuator when

vehicle speed is less than 5 km/h (3MPH)

vehicle security system is disarmed or pre-armed phase
BCM does not open trunk lid opener actuator when

trunk lid opener cancel switch is OFF (CANSEL)

vehicle speed is more than 5 km/h (3MPH)

vehicle security system is armed or alarm phase

Intelligent Key is inserted in key slot

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2007 April2007 M35/M45
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 50A fusible link (letter F , located in the fuse and fusible link box)

to BCM terminal 55,

through 10A fuse [No. 21, located in the fuse block (J/B)]

to BCM terminal 42,

through 10A fuse [No. 71, located in the IPDM E/R]

to IPDM E/R internal CPU,

through 15A fuse [No. 78, located in the IPDM E/R]

to IPDM E/R internal CPU,

through 15A fuse [No. 37, located in the fuse block (J/B)]

to multi-function switch (security indicator) terminal 1.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

through body grounds M16 and M70.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and trunk.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and trunk are
closed and the doors are locked by key fob.
When a door is open, terminal 12 (passenger side door), 13 (rear RH door), 62 (driver side door), 63 (rear LH
door) receives a ground signal from each door switch.
When front door LH is unlocked by power window main switch (door lock and unlock switch), BCM terminal 22
receives an unlock signal from terminal 14 of power window main switch with power window serial link.
When front door RH is unlocked by power window sub-switch (passenger side) (door lock and unlock switch),
BCM terminal 22 receives an unlock signal from terminal 16 of power window sub-switch (passenger side)
with power window serial link.
When front door key cylinder switch is in LOCK position, ground is supplied

to power window main switch terminal 4

through front door key cylinder switch terminals 6 and 4

through body grounds M16 and M70.
When the hood is open, IPDM E/R receives a ground signal

to IPDM E/R terminal 60

through hood switch terminal 2

through hood switch terminal 1

through body grounds E22, and E43.
The IPDM E/R then sends a signal to BCM via CAN communication line.
When the trunk is open, ground is supplied

to BCM terminal 57

through trunk room lamp switch terminal 1

through trunk room lamp switch terminal 2

through body grounds B402 and B405.
