INSPECTION
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.
Standard resistance: 12.5 - 16.5 W
If the resistance is not as specified, replace the solenoid.
(c) Apply battery positive voltage between terminals. Check
that the solenoid operation sound is heard.
If the operation is not as specified, replace the solenoid.
