ECU Status Test
This feature allows testing the response of
vehicle systems. This can be useful when
troubleshooting or checking the proper working
order of senders and other components.
In ECU Status Test mode, the MCD will monitor
the system and display the data on the screen.
Up to two components can be monitored at
once.
To perform a status test:
1. When in DIAGNOSTIC MODE, highlight
ECU STATUS TEST using the arrow keys;
2. Press enter key;
3. Using the arrow and enter keys, enter a MID
and PID (or PPID);
4. Press enter key;
The MCD now displays in real time the value of
the component. The example below shows how
changing the throttle position will be displayed on
the MCD. That way one can verify if any
identifiable sender unit is working properly or
whether the link is OK.
5. Press Esc key to exit.

In this example, a throttle pedal in good working
order will send a linear and continuous (no
jumps) signal to the ECU, appearing as DATA
value on the MCD screen. Full pedal movement
will display values from 000 (no throttle) to 250
(maximum throttle).
Note: The MCD can perform a status test on as
many as two components simultaneously. To do
so, when setting MID and PID codes, set a
second (non zero) MID and PID code.
DATA LOG MODE
This feature shows total accumulated distance,
fuel used engine hours and idle time.
1. To access data log:
2. Highlight DATA LOG MODE using the arrow
keys;
3. Press enter key to confirm;
The screen shows TOTALS highlighted.
4. Press enter key;
5. View totals using the arrow keys.
Exit by pressing the Esc key.
