VEHICLE SIGNALS

A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
CAUTION:
In case of confirming light signal, set D/N mode to ON/OFF
of light switch (normal setting).

OFF: D (Day mode)

ON: N (Night mode)
Unless above setting, light signal (ON/OFF) may not be
accurately displayed.

If vehicle speed is NG, refer to AV- 1 4 9 , "Vehicle Speed Signal Check for NAVI Control Unit" .

If light is NG, refer to AV- 1 5 1 , "Illumination Signal Check for NAVI Control Unit" .

If IGN is NG, refer to AV- 1 5 2 , "Ignition Signal Check for NAVI Control Unit" .

If reverse is NG, refer to AV- 1 5 2 , "Reverse Signal Check for NAVI Control Unit" .

Name of the place vary with the
screen.Some thinning of the character data is done to
prevent the display becoming to complex. In
some cases and in some locations, the display
contents may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing.System is not malfunction.
Vehicle mark is not positioned cor-
rectly.Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF.Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON.The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function.Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.

BCS-4
BCM (BODY CONTROL MODULE)
Revision: 2004 November 2004 FX35/FX45

BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp has a dual system switch.
4. Sample operation: (When lighting switch 1st position turned ON)

When lighting switch 1st position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.

When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that light-
ing switch 1st position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communi-
cation.

When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and rec-
ognizes that lighting switch 1st position is continuously ON.

BCS-6
BCM (BODY CONTROL MODULE)
Revision: 2004 November 2004 FX35/FX45
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status

With ignition switch ON, CAN communicates with other control units normally.

Control by BCM is being operated properly.

When ignition switch is OFF, switching to sleep mode is possible.

Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status

This status shuts down CAN communication when ignition switch is turned OFF.

It transmits sleep request signal to IPDM E/R and combination meter.

Two seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status

With ignition switch OFF, CAN communication is not active.

With ignition switch OFF, control performed only by BCM is active.

Three seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status

BCM is activated with low current consumption mode.

CAN communication is not active.

When CAN communication operation is detected, it switches to CAN communication status.

When a state of the following switches changes, it switches to CAN communication state.
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH)
–Back door opener switch
–Combination switch (passing, lighting switch 1st position, Front fog lamp)
–Key fob (lock/unlock signal)
–Key cylinder switch

When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.

Status of combination switch reading function is changed.
