Electrical system –circuit EL - 211

System description: IN

The battery current flows from the fuse F\L5 in the vehicle frame fuse box, through the fuse F29 in the
instrument panel fuse box to the pin 2 of the combination instrument B014 pin, to provide power supply for DI
the combination instrument.

The ignition switch is at ON/ST position, and the current flows through the fuse F12 in the instrument panel
EG
fuse box to the pin 10 of the combination instrument B014 to provide power supply for the IG1 .

Fuel level low indicator
TR
The warning signal of fuel low level is output from the pin 3 of the fuel sensor F031 pin to the pin 22 of the

combination instrument B014, the pin 2 of the fuel level sensor F031 is internally earthed by connecting
AX
it with the pin 9 of the combination instrument B014, so that the fuel level can be detected.

Fuel water separation alarming lamp
FR
The monitor signal is input from the terminal 47 of the plug & socket connector A001 of the engine ECU, and
is internally earthed via the terminal 474 of the plug & socket connector A001 of the ECU to determine if
the water level inside the oil–water separator is higher than the design value. At the same time, the signal is ST
sent via CAN to the combination instrument.
Charging failure indicator BR
The current is output from the pin 6 of the combination instrument B014 pin 6 to the pin of the generator F030
pin 1, to determine if the generator is at proper working condition.
BW
Safety belt indicator

The current is output from the pin 13 of the combination instrument B015 to the pin 1 of the seat belt warning
EL
switch G003 and is earthed at pin 2, to determine if the driver has fixed the seat belt..

Indictor lamp of driver cab tilt unlocked

The current is output from the pin 21 of the combination instrument B014 to the pin 1 of the driver cab

unlocked switch G006 pin 1 and is earthed at the pin 2, to determine if the tilting mechanism of the driver cab

has been fixed.

Brake warning indicating lamp

The current is output from the pin 17 of the combination instrument B015 to the pin 1 of the hand brake
switch B075 and is earthed at the pin 2, to determine if the hand brake has been engaged.

ABS failure alarming indicator
The ABS system failure warning signal is output from the terminal 15 of the plug & socket connector B063 of
the ABS ECU, and through hard wires to the pin 2 of the combination instrument B015 pin 2, to determine if
there is any failures about the ABS system.
Exhaust braking indicator
The handle of the windshield wiper combination switch is put into the exhaust brake switch position, under
the control of the engine ECU module F099, the relay R11 coil of the exhaust brake is powered up. The

battery current flows through the contacts of the exhaust brake relay R11 to pin 1 of the exhaust brake

solenoid valve F023 and the brake solenoid valve is activated. At the same time, the engine ECU module

controls the exhaust brake indicating lamp to work normally on via the CAN communication wires.

Air filter alarming lamp for blocking

The current is output from the pin 19 of the combination instrument B014 to the pin 1 of the air filter

block warning switch F025 pin 1, and is earthed at pin 2 to determine if the air filter is blocked.
