SYSTEM DESCRIPTION
 When turning ON the AC 120 V outlet main switch with the ignition switch ON, the indicator turns ON and the
inverter unit is activated.
 The inverter unit converts power supply voltage to AC 120 V and outputs the converted voltage to the AC
120 V outlet two seconds after the AC 120 V outlet main switch is turned ON.
Fail-safeINFOID:0000000006257269
When a malfunction listed below occurs, the inverter unit turns OFF the AC 120 V outlet main switch indicator
and stops the output by operating the fail-safe.
JSMIA0295GB
Malfunction item Fail-safe condition Fail-safe cancellation condition
Inverter unit is overheat-
ed When the inverter unit is overheated, the output
stops to protect the inverter unit. After the inverter unit temperature is lowered, the
AC 120 V outlet main switch ON
⇒ OFF ⇒ ON op-
eration allows normal return.
Inverter unit power sup-
ply voltage is 11.5 V or
less When inverter unit input voltage is lowered, the out-
put stops to protect the battery from running out.
Automatic normal return wh
en inverter unit power
supply voltage reaches 11.5 V - 16 V.
Inverter unit power sup-
ply voltage is 16 V - 18 V When inverter unit input voltage reaches 16 V - 18 V,
the output stops to protect the inverter unit. Automatic normal return wh
en inverter unit power
supply voltage reaches 11.5 V - 16 V.
Inverter unit power sup-
ply voltage is 18 V or
more When inverter unit input voltage reaches 18 V or
more, the output stops to protect the inverter unit. After the inverter unit power supply voltage reaches
11.5 V - 16 V, the AC 120 V outlet main switch ON
⇒
OFF ⇒ ON operation allows normal return.
Inverter unit output cur-
rent is 2.8 A or more When inverter unit output current reaches 2.8 A or
more, the output stops to prevent over current. (e.g.
connecting an electric appliance exceeding rated
output)
Automatic normal return wh
en inverter output cur-
rent reaches 2.8 A.
Inverter unit output signal
(AC 120 V output signal)
is shorted When inverter unit output signal is shorted, the out-
put stops. After recovering from inverter unit output signal
short, the AC 120 V outlet main switch ON
⇒ OFF
⇒ ON operation allows normal return.

SUNROOF SYSTEM
 Sunroof motor assembly operates with the power supply that is output from BCM while ignition switch is ON
or retained power is operating.
 Tilt up/down & slide open/close signals from sunroof s witch enables operate sunroof motor to move arbi-
trarily.
 Sunroof motor assembly receives a vehicle speed signal from combination meter and controls the sunroof motor operation.
AUTO OPERATION
Sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof with-
out holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.
RETAINED POWER OPERATION
 Retained power operation is an additional power supply function that enables sunroof system to operate dur-
ing 45 seconds even when ignition switch is turned OFF.
Retained power function cancel conditions
 Front door CLOSE (door switch OFF) →OPEN (door switch ON).
 When ignition switch is ON again.
 When timer time passes. (45 seconds)
ANTI-PINCH FUNCTION
The CPU of sunroof motor assembly monitors the s unroof motor operation and the sunroof position (fully-
closed or other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until full up position (when tilt down operate) or
150 mm (5.91 in) or more in an open direction (when slide close operate):
