the moment a particular
DTC is detected While turning BCM status from low power consumption mode to
normal mode (Power supply position is “LOCK”)
SLEEP>OFF While turning BCM status from low power consumption mode to
normal mode (Power supply position is “OFF”.)
LOCK>ACC While turning power supply position from “LOCK” to “ACC”
ACC>ON While turning power supply position from “ACC” to “IGN”
RUN>ACC While turning power supp
ly position from “RUN” to “ACC” (Vehicle
is stopping and selector lever is except P position.)
CRANK>RUN While turning power su
pply position from “CRANKING” to “RUN”
(From cranking up the engine to run it)

LOCK>SLEEP While turning BCM status from normal mode (Power supply posi-
tion is “LOCK”.) to low power consumption mode
LOCK Power supply position is “LOCK”
(Ignition switch OFF with steer-
ing is locked.)
OFF Power supply position is “OFF” (Ignition switch OFF with steering
is unlocked.)
ACC Power supply position is “ACC” (Ignition switch ACC)
ON Power supply position is “IGN” (Ignition switch ON with engine
stopped)
ENGINE RUN Power supply position is “RUN” (Ignition switch ON with engine
running)
CRANKING Power supply position is “CRANKING” (At engine cranking)
IGN Counter 0 - 39 The number of times that ignition switch is turned ON after DTC is detected
The number is 0 when a malfunction is detected now.
The number increases like 1
→ 2 → 3...38 → 39 after returning to the normal condition
whenever ignition switch OFF → ON.
The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
Monitor Item Description
DOOR SW-DR Indicates [ON/OFF] condition of driver side door switch.
DOOR SW-AS Indicates [ON/OFF] condition of passenger side door switch.

FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and
direction of door glass. Switches to fail-safe control w hen a signal that is out of the specified value is detected
between the fully closed position and the actual position of the glass.
If fail-safe control, the system changes to a non-in itialized condition and the following function do not operate.
Auto-up operation
Anti-pinch function
Retained power function
When fail-safe control is activated, perform initialization procedure to recover. If a malfunction is detected in
power window switch or more, fail-safe control is activated again.
