2. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure resistance between termi-
nals.
Standard resistance: 12.5 ± 16.5 W
If resistance value is not as specified, replace the solenoid.
(c) Apply battery positive voltage between terminals. Check
that an operation noise can be heard from the solenoid.
If the solenoid does not operate, replace the solenoid.
