signal. If the
signal is
low, the
buzzer
sound.
Otherwise
the buzzer
will be off.

Self-Test
When the ignition switch is turned on, there are seven LED
warning lamps under the control of the software. These alarm
lamps are:
–
Engine Overheating Warning Lamp
– Fuel Level Too Low Warning Lamp
– ABS Failure Warning Lamp
– Engine Emissions Failure Warning Lamp
–
Engine System Failure Warning Lamp
– Airbag Fault Warning Lamp
– EBD Fault Warning Lamp
When the engine speed is greater than 300 rpm, self-test is
interrupted.
Gages
After the engine is shut down, all gages return to zero.
Speedometer
There are two kinds speed signals used to calculate the speed.
One is obtained from the EMS module CAN message signal,
the other is the vehicle speed sensor frequency signal. When
the ignition system is turned on, the instrument cluster system
determines calculate the speed with which speed signal.
Priority is as following: CAN bus through the acquisition from
the EMS speed signal is greater than the speed sensor.
Specific speed signal switching in the following strategies:
– If the ICU can not receive messages in continuous five
cycles, or EMS received CAN speed message is not valid,
the system switched to using the frequency sent from the
speed sensor signal to calculate speed within 50 ms.
– If the CAN speed message is back to normal, and maintains
continuous five cycles, the system switches back to using
the CAN speed signal to calculate speed within 50 ms.
Engine Tachometer
Engine speed data is from the CAN bus, sent by EMS.
Instrument micro-controller accepts the signal, calculates the
engine speed, and then drives a stepper motor to point to the
appropriate location (rpm/min).
The behavioral characteristics of the engine tachometer is as
following:
– When the engine is turned off, if the battery has been
connected, the engine tachometer pointer is back to the "0"
position.
– If the battery is disconnected, the engine tachometer
pointer does not return to the "0" position; When the battery
is connected again, the engine tachometer pointer is back
to the "0" location
– If the engine speed signal from the CAN is invalid or missing
for 5 s, the engine tachometer pointer will return to "0"
position.
