SELECTOR LEVER OPERATION CHECK

M1231001300062

1. Apply the parking brake, and check that the selector lever

moves smoothly and accurately to each range position.

2. Check that the engine starts when the selector lever is at the

N or P position, and that it does not start when the selector
lever is in any other position.

3. Start the engine, release the parking brake, and check that

the vehicle moves forward when the selector lever is moved
from N range to D, 3, 2 or L range, and that the vehicle
reverses when the selector lever is moved to R range.

4. Stop the engine.

5. Turn the ignition switch to the ON position, and check that

the backup lamp illuminates and the buzzer sounds when
the selector lever is shifted from P to R range.

NOTE: The A/T mis-operation prevention mechanism is
provided so that the selector lever cannot be moved from
the P position if the ignition switch is at a position other than
the LOCK (OFF) position and the brake pedal is not
depressed.

KEY INTERLOCK MECHANISM CHECK

M1232000900075

1. Carry out the following inspection.

2. When any of the above checks are not normal, adjust the

key interlock cable in following procedure.

(1) Remove the floor console. (Refer to GROUP 52A

−

console

P.52A-11

.)

(2) Shift selector lever to "P."
(3) Turn the ignition key to "LOCK" (OFF) position.
