A/T SHIFT LOCK SYSTEM
Description INFOID:0000000004305498
• The mechanical key interlock mechanism also operates as a shift lock: With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other position
unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and sli der located inside key cylinder, respectively.

•
Selector lever can be moved fr om “P” position with ignition key in ON position and brake pedal
released.
• Selector lever can be moved from “P” position when ignition switch is removed from key cylinder.
SYMPTOM 2:
• Ignition key cannot be removed when sel ector lever is set to “P” position.
• Ignition key can be removed wh en selector lever is set to any position except “P” position.OK >> GO TO 2.

2. Remove the control cable nut (A) and control cable (1) and place the manual lever (2) in the "P'"position.
3. Place selector lever in “P” position.
4. Hold control cable (1) at the end and pull it with a force of 9.8 N (approximately 1 kg, 2.2 lb). Release the control cable and tem-
porarily tighten control cable nut (A).
5. Tighten control cable nut (A) to the specified torque.
CAUTION:
Secure manual lever when tightening nut.
6. Move selector lever from “P” to "1" position again. Make sure that selector lever moves smoothly.
7. Check A/T position. Refer to AT-216, " Checking of A/T Position " .
8. Install air duct assembly. Refer to EM-139 .
Checking of A/T Position INFOID:0000000004305497
1. Place selector lever in “P” position, and tu rn ignition switch ON (Do not start engine).
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm 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 sele ctor lever is in matches the position shown by the
shift position indicator and the transaxle. SCIA6972E

7. Remove steering column cover (upper and lower) and instru-
ment lower finisher. Refer to IP-11 .
8. Pull out the lock plate (A) from the holder (B).
9. Remove the key interlock cable (1) from the key cylinder (2).
10. Remove the clip (A), and then remove the key interlock cable (1).
INSTALLATION CAUTION:
• Install key interlock cable in such a way that it will not be damaged by sharp bends, twists or interfer-
ence with adjacent parts.
• After installing key interlock cable to contro l device assembly, make sure that casing cap and
bracket are firmly secured in their positions.
1. Place the selector lever in the “P” position.
2. Turn ignition switch to “ACC” or “ON” position.
3. Set the key interlock cable (1) to the key cylinder (2).
4. Install the lock plate (A) to the holder (B).
5. Turn ignition switch to “LOCK” position.
6. Temporarily install the adjust holder (A) to the key interlock rod (B).
7. Install the casing cap (C) to the cable bracket (D) on the control device assembly.
CAUTION:
• Do not bend or twist key interlock cable excessively when
installing.
• After installing key interlo ck cable to cable bracket (D) on
control device assembly, make sure casing cap (C) is
firmly secured in cable bracket (D) on control device
assembly.
• If casing cap (C) is loose [less than 39.2 N (4.0 kg, 8.8 lb)
removing force], replace key interlock cable.
