INSPECTION
INSPECT ECT SWITCH
(a) Using an ohmmeter, check that no continuity exists be-
tween the terminals when the coolant temperature is
above 100 °C (212 °F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that continuity exists between
the terminals when the coolant temperature is below
91 °C (196 °F).
If there no continuity exists, replace the switch.

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

2. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals 3 and 4.
Standard resistance: 12 ± 17 W
If the resistance value is not as specified, replace the solenoid.
(c) Touch the solenoid with your finger and check that the so-
lenoid operation can be felt when battery voltage is ap-
plied intermittently to terminals 3 and 4.
If the operation is not as specified, replace the solenoid.
