• Removal and installation of the door glass.
• Removal and installation of the door glass run.
Initialization
After installing each component to the vehicle, follow the steps below.
1. Disconnect the battery negative c able or disconnect power window switch's harness connector tempo-
rarily, then reconnect after at least 1 minute.
2. Turn ignition switch ON.
3. Open the window to its full width by operating the power window switch. (Exclude this procedure if the window is already fully opened).
4. Move the power window switch in the up direction (auto close position) and hold. Keep holding the switch
even when window is completely closed, and then release after 4 seconds have passed.
5. Confirm window is now operating correctly. NOTE:
Initialization may be cancelled with continuous opening and closing operation. In this case, initialize the
system.
INSPECT THE FUNCTION OF THE ANTI-PINCH SYSTEM
1. Fully open the door glass.
2. Place a wooden piece (wooden hammer handle, etc.) near the fully closed position.
3. Carry out fully closing operation with auto up switch.
• Check that the glass reverses without pinching the w ooden piece, is lowered approx.150 mm (5.91 in) or for
2 seconds and then stops.
• The glass should not be raised with power window main switch while it is reversing or lowering.
CAUTION:
• Use care to avoid being pinched during the inspection. Do not u se a hand, etc. in place of the
wooden piece durin g the inspection.
• Check that auto up function is normal before inspection, following the system initialization.
FITTING INSPECTION
• Make sure the glass is securely fit into the glass run groove.
• Lower the glass slightly [approx. 10 to 20 mm (0.39 to 0.79 in)] and make sure the clearance to the sash is
parallel. If the clearance between the glass and sash is not parallel, loosen the regulator bolts, guide rail
bolts, and the glass and guide rail bolts to correct the glass position.
• Make sure the system is normal with raising and lowering the glass.

Component Parts and Har ness Connector LocationINFOID:0000000005929497
System DescriptionINFOID:0000000005929498
The rear window defogger system is controlled by BCM (body control module) and IPDM E/R (intelligent
power distribution module engine room).
The rear window defogger only operates for approximately 15 minutes.

REAR WINDOW DEFOGGER
Power is supplied at all times
• through 15A fuses (No. 46 and 47, located in the IPDM E/R)
• to rear window defogger relay
• through 10A fuse [No. 5 (with heated mirrors), located in the fuse block (J/B)]
• to heated mirror relay terminal 3
• through 40A fusible link (letter g , located in the fuse and fusible link box)
• to BCM terminal 70.
With the ignition switch turned to ON or START position, power is supplied
• through ignition relay
• to rear window defogger relay (located in the IPDM E/R)
• through 10A fuse [No. 6, located in the fuse block (J/B)]
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67 and
• to front air control terminal 8
• through body grounds M57 and M61
• to IPDM E/R terminals 39 and 59
• through body grounds E15 and E24.
When front air control (rear window defogger switch) is turned to ON, ground is supplied
• to BCM terminal 9
• through front air control terminal 3
• through front air control terminal 8
• through body grounds M57 and M61.
Then rear window defogger switch is illuminated.
Then BCM recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to IPDM E/R via CAN communication (CAN-H, CAN-L).
When IPDM E/R receives rear window defogger switch signals, ground is supplied
• to rear window defogger relay (located in the IPDM E/R)
• through IPDM E/R terminals 39 and 59
• through body grounds E15 and E24
Then rear window defogger relay is energized.
With power and ground supplied, rear window def ogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON (with heated mirrors), power is supplied
• through heated mirror relay terminal 5
• to door mirror (LH and RH) terminal 1.
Door mirror (LH and RH) is grounded through body grounds M57 and M61.
With power and ground supplied, rear window defogger filaments heat and defog the rear window and door
mirror filaments heat and defog the mirrors.
