Notches

(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.

If the result is not as specified, replace the air mix control servo motor.

2. INSPECT AIR MIX CONTROL SERVO MOTOR (for Automatic Air Conditioning System)

(a) Inspect the servo motor operation.

(1) Connect the positive (+) lead from the battery to terminal 7 (MHD) and negative (-) lead to terminals 1 (SG), then check that the shaft rotates clockwise smoothly.

(2) Connect the positive (+) lead from the battery to terminal 6 (MCD) and negative (-) lead to terminal 1 (SG) then check that the shaft rotates counterclockwise smoothly.

If the operations are not as specified, replace the air mix control servo motor.
