5.9.5 EFI Self-Diagnosis
ECU constantly monitors sensors, actuators, circuits, MIL, battery voltage etc., even
itself. It also tests sensors output signal, actuator drive signal and inner signal (such as
closed-loop control, coolant temp., signal, idle speed control, battery voltage control etc.
for reliability). If any malfunction or suspectable signal found, ECU would record the fault
information in RAM.
Fault information comes in form of fault codes, which are then displayed on PDA, in
sequence of which fault comes first.
PDA or MIL can be used to locate the part in trouble immediately after fault happens.
The EFI system can do self-diagnosis by MIL indicator and PDA.
5.9.5.1
MIL
MIL is a light-emitting diode and located
on instrument panel. It indicates different
fault codes through the flashes in different
frequency.
MIL Circuit: The current to ECU's C1 pin
should be less than 0.1A.
MIL flash principles:
a
:
In flashing mode and no trouble in
memory
If the ECU shows MIL on flashing mode.
The MIL indicator will flash to show the
fault codes in memory. MIL keeps on
since the ECU formats. If MIL keeps on. It
means no trouble. The indicator will be off
after the engine start.
b
:
In MIL mode and the got trouble code
(Including engine start and not start)
MIL turns on for 5 seconds and turns off.
Then MIL flashes to indicate a fault code:
The interval between fault codes is 3.5s,
between digits is 1.2s, and a flash lasts
for 0.4s as well as the interval between 2
flashes. MIL flashes 10 times to indicate 0.
For 1-9, how much it counts depends on
how many times MIL flashes.
