Step 5.
Perform self-test on EGS (3) (Para G-3).
If `N' LED (4) is ON, and `T' LED (5) is blinking, replace EGS (3) (Para 12-25).
If `N' LED (4) is ON, and `T' LED (5) is ON, proceed to Step 6.
If `N' LED (4) is ON, `T' LED (5) is ON, and `1' LED (6) is RED, proceed to Step 9.
If `N' LED (4) is ON, `T' LED (5) is ON, and `2' LED (7) is RED, proceed to Step 10.
If `N' LED (4) is ON, `T' LED (5) is ON, and `3' LED (8) is RED, proceed to Step 11.
If `N' LED (4) is ON, `T' LED (5) is ON, and `4' LED (9) is RED, proceed to Step 12.
If `N' LED (4) is ON, `T' LED (5) is ON, and `R' LED (10) is RED, proceed to Step 13.
Step 6.
Perform input test on EGS (3) (Para G-3).
If a fault is detected, replace EGS (Para 12-25).
If no fault is detected, proceed to Step 7.
Step 7.
Perform output test on EGS (3) (Para G-3).
If a fault is detected, replace EGS (Para 12-25).
If no fault is detected, proceed to Step 8.
Step 8.
Perform speed sensor test on EGS (3) (Para G-3).
If a lamp test fault is detected, replace EGS (Para 12-25).
If a speed display fault is detected, replace speed sensor (Para 12-34.3).
