(a) Inspect the servo motor operation. Text in Illustration
(1) When 12 V is applied between terminals 4 (IGN) and 1 (GND), and 0 V is applied between terminals 2 (SIG) and 1 (GND), check that the line connecting the 2 notches moves to the 0 V position. If the result is not as specified, replace the air mix control servo motor. (2) When 12 V is applied between terminals 4 (IGN) and 1 (GND), and 6 V is applied between terminals 2 (SIG) and 1 (GND), check that the line connecting the 2 notches moves to the 6 V position. If the result is not as specified, replace the air mix control servo motor. (3) When 12 V is applied between terminals 4 (IGN) and 1 (GND), and between terminals 2 (SIG) and 1 (GND), check that the line connecting the 2 notches moves to the 12 V position.
