PROCEDURE
1. INSPECT MODE CONTROL SERVO MOTOR
(a) Inspect the servo motor operation. (1) When 12V is applied between terminals 4 (IGN) and 1 (GND), and 0V is applied between terminals 2 (SIG) and 1 (GND), check that the line connecting the 2 notches moves to the 0V position. If the result is not as specified, replace the mode control servo motor. (2) When 12V is applied between terminals 4 (IGN) and 1 (GND), and 6V is applied between terminals 2 (SIG) and 1 (GND), check that the line connecting the 2 notches moves to the 6V position. If the result is not as specified, replace the mode control servo motor. (3) When 12V 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 12V position. If the result is not as specified, replace the mode control servo motor. |
