MAGNET CLUTCH
DescriptionINFOID:0000000012430746
SYSTEM DESCRIPTION
When the blower speed dial is in one of the fan speed pos itions, the front air control outputs a fan ON signal to
the BCM. When the A/C switch is pressed, the A/C switch LED illuminat es and the front air control outputs a
compressor ON signal to the BCM. Any mode control button can be selected. As long as the BCM receives a
compressor ON signal and a fan ON signal from the front air control, the conditions required for the BCM to
transmit a compressor ON request to the ECM have been met.
The BCM sends a compressor ON signal to ECM, via CAN communication line.
The ECM judges whether the compressor can be turned ON, based on each sensor status (refrigerant pres-
sure sensor signal, throttle angle sensor, etc.). If it judges the compressor can be turned ON, it sends a com-
pressor ON signal to IPDM E/R, via CAN communication line.
Upon receipt of a compressor ON signal from ECM, IPDM E/R turns the A/C relay ON to operate the compres-
sor.

Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace the blown fuse after repairing the affected circuit.
2.CHECK MAGNET CLUTCH
1. Turn ignition switch OFF.
2. Disconnect compressor connector.
3. Directly apply battery voltage to the magnet clut ch. Check for operation visually and by sound.
Does it operate normally?
YES >> GO TO 3.

The BCM controls power and ground to all interior lamps.
After the battery saver system turns the la mps OFF, the lamps will illuminate again when
• a signal is received from a key fob, main power window and door lock/unlock switch, power window and
door lock/unlock switch RH or when the front door lock assembly LH (key cylinder switch) is locked or
unlocked
• a door is opened or closed
• the key is removed from or inserted into t he ignition switch (without Intelligent Key system).
The interior lamp battery saver control time per iod can be changed with the function setting of CONSULT.
ILLUMINATION CONTROL SYSTEM
ILLUMINATION CONTROL SYSTEM : System DescriptionINFOID:0000000012432723
SYSTEM DIAGRAM
OUTLINE
The illumination lamps operation is dependent upon the posit ion of the combination switch (lighting and turn
signal switch). When the combination switch (lighting and turn signal switch) is placed in the 1ST or 2ND posi-
tion the BCM (body control module) receives input requesting the parking lamps to illuminate. This input is
communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communica-
tion lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized,
this relay directs power to the parking and illumination lamps, which then illuminate.
BATTERY SAVER CONTROL
When the combination switch (lighting and turn signal switch) is in the 1st or 2nd position and the ignition
switch is turned from ON or ACC to OFF, the battery saver control feature is activated. Under this condition,
the illumination lamps remain illuminated for 10 minutes unless the combination switch (lighting and turn signal
switch) position is changed. If the combination switch (lighting and turn signal switch) position is changed, then
the illumination lamps are turned off after a 15 second delay. When the combination switch (lighting and turn
signal switch) is turned from OFF to 1st or 2nd position after illumination lamps have been turned off by the
battery saver control, the illumination lamps illuminate again.
