Checking The Control Panel

Check if the signal from the control panel is received by the control module.

Read off the value.

HINT: When checking the control panel, check if the resistance between terminal #6C and the terminal pin is 0 Ω. OFF is displayed when there is a short-circuit to supply voltage. ON is displayed when there is a short-circuit to ground. 

When operated, the value should oscillate between ON and OFF.
