FAIL-SAFE CONTROL
The encoder signal detects the up / down speed / detection of door glass. If the malfunction is detected to the
encoder signal or the difference between the glass fully closed position (memorized in power window main
switch or power window sub-switch) and the actual glass position is detected, it shifts into the fail-safe control
It is shifts into the fail-safe control, the initialization is not performed and the following function is not activated
Auto up operation
Anti-pinch function
It is shifts into the fail-safe control, performed the initialization to resume normal operation condition.
POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH
When ignition key switch is OFF, front power window can be opened or closed by turning the key cylinder
switch UNLOCK / LOCK position more than 1.5 second over condition.
Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.
Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.
The power window DOWN stops when the following operations are carried out.
While performing open / close the window, power window is stopped at the position as the door key cylin-
der is placed on NEUTRAL.
When the ignition switch is turned ON while the power window DOWN is operated.
DTC Condition
Pulse sensor detects malfunctionDuring the glass opening/closing operation, a pulse signal is continuously
detected for the specified terms or more
Both pulse sensors detect malfunctionDuring the glass opening/closing operation, both pulse signals are not
detected for the specified values or more
Pulse direction malfunctionThe following condition is detected for the specified values or more. The
pulse signal (detected during glass open/close operation) detects the
opposite direction to the driving direction of power window motor.
Glass recognized position malfunction 1During the glass opening/closing operation, the difference between the
glass fully closed position (memorized in power window main switch or
power window sub-switch) and the actual glass position is detected for
the specified values or more.
Glass recognized position malfunction 2During the glass opening/closing operation, a pulse count is detected that
is above the glass full stroke
Glass fully closed position not updated malfunctionContinuously perform the glass open/close operation (with the glass not
fully closed) at the specified value (approx. 10 time) or more

to BCM terminal 55,
through 10A fuse [No. 21, located in the fuse block (J/B)]
to BCM terminal 42.
With the ignition switch turned to ON or START position,
Power is supplied
through 15A fuse [No. 1, located in the fuse block (J/B)]
to BCM terminal 38.
through 10A fuse [No. 12, located in the fuse block (J/B)]
to rear window defogger relay terminal 1.
With the ignition switch turned to ACC or ON position,
through 10A fuse [No. 6, located in the fuse block (J/B)]
to multi-function switch terminal 2.
Ground is supplied
to BCM terminal 52
through body grounds M16 and M70,
to multi-function switch terminal 14
through body grounds M16 and M70,
to IPDM E/R terminals 38 and 51
through body grounds E22 and E43.
When rear window defogger switch in multi-function switch is turned to ON.
Then multi-function switch recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to AV control unit (without navigation system) or NAVI con-
trol unit (with navigation system) via AV line.
When AV control unit (without navigation system) or NAVI control unit (with navigation system) receives rear
window defogger switch signals, and display on the screen.
Then AV control unit (without navigation system) or NAVI control unit (with navigation system) recognizes that
rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signal to BCM via DATA LINE (CAN H, CAN L).
Then BCM recognizes that rear window defogger switch signal.
Then it sends rear window defogger request signal to IPDM E/R via DATA LINE (CAN H, CAN L).
When IPDM E/R receives rear window defogger switch signals,
Ground is supplied
to rear window defogger relay terminal 2
through IPDM E/R terminal 57
through IPDM E/R terminal 51
through body grounds E22 and E43.
And then rear window defogger relay is energized.
When rear window defogger relay is turned ON, signals are transmitted.
through rear window defogger relay terminals 5 and 7
through condenser terminal 1
to rear window defogger terminal 1
Rear window defogger terminal 2 is grounded through grounds B702.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON,
Power is supplied
through rear window defogger relay terminals 5 and 7
through fuse block (J/B) terminal 2C
through 10A fuse [No. 8, located in the fuse block (J/B)] and
through fuse block (J/B) terminal 5B
to door mirror (LH and RH) terminal 4.
Door mirror (LH and RH) terminal 8 is grounded through body grounds M16 and M70.
