Checking of A/T PositionNCS001QO
1. Place selector lever in “P” position, and turn ignition switch ON (engine stop).
2. Make sure that selector lever can be shifted to other than “P” position when brake pedal is depressed.
Also make sure that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the A/T body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
9. Make sure that A/T is locked completely in “P” position.
10. When selector lever is set to manual shift gate, make sure that manual mode is displayed on combination
meter.
Shift selector lever to “+” and “-” sides, and check that set shift position changes.
