Data are reference values.
NOTE:
Confirm that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscillo scope, it
should be observed that the power source voltage lasts for 3.5 to 10 ms.

Revision: November 20092006 QX56
Component InspectionECS00ENY
SHIFT LOCK SOLENOID

Check operation by applying battery voltage to A/T device termi-
nal 9 and ground to terminal 10.
CAUTION:
Be sure to apply the voltage of the correct polarity to the
respective terminals. Otherwise, the part may be damaged.
DETENTION SWITCH
For key:

Check continuity between terminals of the A/T device.
DETENTION SWITCH
For shift:

Check continuity between terminals of the A/T device.

REMOVAL
1. Remove negative battery terminal. Refer to SC-4, "BATTERY" .
2. Remove A/T finisher. Refer to IP-13, "
A/T FINISHER" .
3. Disconnect selector control cable.
4. Disconnect A/T device harness connector.
5. Remove control device assembly.
INSTALLATION
Installation is in reverse order of removal. Be careful of the following:

After installation is completed, adjust and check A/T position.
Adjustment of A/T PositionECS00EO0
1. Loosen nut of control cable.
2. Place PNP switch and selector lever in “P” position.
3. After pushing the control cable in the direction shown with a force of 9.8 N ·m (1kg-m, 2.2 lb-ft), release it. This is in the natu-
ral state, tighten control cable nut to specifications.
Checking of A/T PositionECS00EO1
1. Place selector lever in “P” position, and turn ignition switch ON
(engine stop).
2. Make sure selector lever can be shifted to other than “P” posi-
tion when brake pedal is depressed. Also make sure 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 transmission body.
5. The method of operating the lever to individual positions correctly should be as shown.
6. Confirm the back-up lamps illuminate only when lever is placed in the “R” position. Confirm the back-up
lamps does not illuminate when selector lever is pushed against “R” position in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in the “P” and “N” positions.
8. Make sure transmission is locked completely in “P” position.
Control cable nut : 14.5 N·m (1.5 kg-m, 11 ft-lb)
