1. INSPECT SHIFT LOCK CONTROL ECU
Using a voltmeter, measure the voltage at each terminal.
HINT:
Do not disconnect the ECU connector.

2. INSPECT SHIFT LOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal 1 and 2.
Standard resistance: 21 - 27 W
If the resistance value is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals.
Check that the operation noise can be heard from the so-
lenoid.
If the solenoid does not operate, replace the solenoid.
3. INSPECT SHIFT LOCK CONTROL SWITCH
Inspect that continuity exists between each terminal.

4. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal 1 and 2.
Standard resistance: 12 - 17 W
If resistance value is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals 1
and 2. Check that an operation noise can be heard from
the solenoid.
If the solenoid does not operate, replace the solenoid.

TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT ONE-WAY CLUTCH
(a) Install SST so that it fits in the notch of the converter hub
and outer race of the one-way clutch.
SST 09350-30020 (09351-32020)
(b) Press on the serrations of stator with a finger and rotate
it.
(c) Check if it rotates smoothly when turned clockwise and
locks up when turned counterclockwise.
If necessary, clean the converter clutch and retest the one-way
clutch.
Replace the converter clutch if the clutch still fails in the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
If runout is not within the specification or if the ring gear is dam-
aged, replace the drive plate. If installing a new drive plate, note
the orientation of the spacers and tighten the bolts.
Torque:
1st: 49 N´m (500 kgf´cm, 36 ft´lbf)
2nd: Turn extra 90°
3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
(a) Temporarily mount the torque converter clutch to the drive
plate.
Set up a dial indicator and measure the torque converter
clutch sleeve runout.
Maximum runout: 0.30 mm (0.0118 in.)
If runout is not within the specification, correct it by reorienting
the installation of the torque converter clutch.
If excessive runout cannot be corrected, replace the torque
converter clutch.
(b) Remove the torque converter clutch.
