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.
