Jumping the pin connector on the ECU will allow the check engine light to flash on the dash console. The check engine light will flash repeatedly and show codes.
You read the codes with a scanner, repair the cause, and clear the code with the scanner.
You can't, you must use a scanner.

I am sorry but you do not without the proper equipment.
What does a engine scanner look like
I have a 2008 toyota fielder and the engine check light came on .when check with a scanner code p1589 shows .where is this sensor located
not without MAJOR modification
An engine scanner will give you exact water temperature and gauging by it you can tell.
A lot of parts stores will check it for free
Repair the problem that turned it on and then clear the code with an OBD2 scanner/code reader
Never mind - I found it. It is on the bottom of the dash above the gas pedal.
To connect an engine code scanner to a 1989 Ford Bronco, locate the diagnostic connector, which is typically found under the dashboard near the steering column. Use a compatible OBD-I scanner, as the Bronco from this year utilizes the OBD-I system. Plug the scanner into the connector, turn the ignition key to the "on" position without starting the engine, and follow the scanner's instructions to retrieve any diagnostic trouble codes.
