							WARNINGS AND INDICATORSE2
CIRCUIT OPERATION2
ETC Warning Indicator (TC)
Illuminates for 3 seconds after the Ignition switch is
turned on and the ABS and traction control systems
have completed their self±checks.
Whilst driving, the TC light will illuminate (for a
minimum of 2 seconds) whenever traction control is
active; the light extinguishing as soon as traction
control ceases. The light flashing (for at least 10
seconds) indicates that the system has been
over±used; it will be available again once the system
components have cooled.
If the light illuminates continuously, a fault with the
system is indicated.
The ABS System is interfaced to the Instrument
Cluster (Z142) via the BeCM (Z238).
Brake Warning Indicator
Illuminates for 3 seconds as a bulb check when the
Ignition switch is turned to position II and also
illuminates when the handbrake is applied and the
Ignition switch is in position II.
The light should extinguish when the handbrake is
fully released or after the bulb check if the
handbrake is off. If the light illuminates whilst driving,
a fault is indicated.
NOTE: If the vehicle has been standing for some
time, it may take up to 40 seconds before the light
extinguishes (in this case, ABS and TC warning
lights will also be illuminated).
The Brake System and Handbrake Switch (X191)
are interfaced to the Instrument Cluster (Z142) via
the BeCM (Z238).
Cruise Active Indicator
When the Cruise Control System has been activated
the indicator will be illuminated. The Cruise System
is interfaced to the Instrument Cluster (Z142) via the
BeCM (Z238).
Charge Warning Indicator
Illuminates as a bulb check when the Ignition switch
is turned to position II and extinguishes when the
engine is running and the Generator (Z106) is
producing normal power. If the Generator (Z106) is
not producing normal power or the Generator (Z106)
stops turning the indicator will illuminate.
Both Petrol and Diesel Generators (Z106) are
interfaced to the Instrument Cluster (Z142) via the
BeCM (Z238).
Fasten Seat Belt Indicator
Illuminates for 6 seconds when the Ignition switch is
turned to position II. When the drivers seat belt is
buckled, the indicator turns off.
The Drivers Seat Belt Switch (X120) is interfaced to
the Instrument Cluster (Z142) via the BeCM (Z238). 
						

							WARNINGS AND INDICATORSE2
CIRCUIT OPERATION3
Air Suspension Indicator
Illuminates as a bulb check when the Ignition switch
is turned to position II and remains illuminated until 2
seconds after the engine has started.
In addition, the light will illuminate whilst driving
whenever 
High or 
Extended ride heights are
selected, and also if a fault with the air suspension
system is detected.
The air suspension system is interfaced to the
Instrument Cluster (Z142) via the BeCM (Z238).
Lights ON
 Indicator
This light illuminates when the sidelights and/or
headlights are switched on. It will not illuminate when
parking lights or headlight delay are in operation.
The Main Light Switch is interfaced to the Instrument
Cluster (Z142) via the BeCM (Z238).
Direction Indicators
The left or right warning indicator flashes in time with
the corresponding left or right direction indicator
lamps whenever they are operated. A warning
indicator flashing twice the normal speed indicates
that a direction indicator lamp bulb has failed (the
message centre will indicate which bulb is faulty). If a
trailer is connected and a rear indicator lamp bulb
fails then the message will not be displayed. When
the hazard switch is pressed, both warning indicators
will illuminate in conjunction with the indicator lamps.
The Direction Indicator switches are interfaced to the
Instrument Cluster (Z142) via the BeCM (Z238).
Main Beam Indicator
This indicator illuminates whenever the main beam
headlights are on.
The Main Beam Switch is interfaced to the
Instrument Cluster (Z142) via the BeCM (Z238).
Trailer Indicator
This indicator is only operative when a trailer is
connected to the vehicle via a multi±pin socket. The
indicator flashes in conjunction with the vehicle
direction indicator lamps, thus confirming that the
trailer indicator lamps are operating correctly. In the
event of a failure of a trailer direction indicator lamp,
the warning indicator will not illuminate.
The Trailer Auxilliary Socket is interfaced to the
Instrument Cluster (Z142) via the BeCM (Z238).
Glow Plug Indicator
This indicator illuminates when the Engine Control
Module (Z132) activates the Glow Plug Timer Unit
(Z135).
The Engine Control Module (Z132) is interfaced to
the Instrument Cluster (Z142) via the BeCM (Z238).
Catalyst Warning Indicator (Japan Only)
This indicator illuminates when a fault in the catalyst
system is detected.
The Catalyst Overheat Sensors (X299, X300) and
the Catalyst Amplifier (X301) are interfaced to the
Instrument Cluster (Z142) via the BeCM (Z238).
Audible Warning
Receipt of an audible warning request signal from a
vehicle parameter/message condition shall cause the
BeCM (Z238) to generate the required number of
warning tones. The actuator sounder unit is located
at the rear of the Instrument Cluster (Z142).
See message listing for categories/priority and levels
of audible warnings.
