6. CHECK INTELLIGENT KEY FUNCTION
Operate Push-button ignition switch with carrying Intelligent Key to check the power source position can be
turned with all of the Intelligent Keys.
CAUTION:
Operate Push-button ignition switch without depressing the brake pedal.
Can be operated with all of the Intelligent Keys>>GO TO 7.
Can not be operated with particular Intelligent Key>>Check the malfunctioning Intelligent Key. Refer to BL-
126, "INTELLIGENT KEY BATTERY INSPECTION" .
Can not be operated with any of the Intelligent Keys>>Perform Diagnostic Procedure. Refer to BL-179,
"Trouble Diagnosis Symptom Chart 1" .
7. CHECK TURNING TIMING OF POWER SOURCE POSITION 1
Check the power source turning delay time after Push-button ignition switch is pushed. (Approx. 3 sec)
CAUTION:
Operate Push-button ignition switch without depressing the brake pedal.
No delay time exists>>GO TO 8.
Delay time exists>>Perform Diagnostic Procedure. Refer to BL-180, "
Trouble Diagnosis Symptom Chart 2" .
8. CHECK TURNING TIMING OF POWER SOURCE POSITION 2
Check all the Intelligent Keys for power source turning delay time after Push-button ignition switch is pushed
with Intelligent Key inserted into key slot. (Approx. 3 sec)
CAUTION:
Operate Push-button ignition switch without depressing the brake pedal.
No delay time exists>>GO TO 9.
Delay time exists when operated with particular Intelligent Key.>>Perform “C/U INITIALIZATION” referring to
CONSULT-II operation manual IVIS/NVIS NATS. In case that delay time still exists after the initial-
ization, replace the Intelligent Key.
Delay time exists when operated with any of the Intelligent Keys.>>Perform Diagnostic Procedure. Refer to
BL-180, "
Trouble Diagnosis Symptom Chart 3" .
9. CHECK ENGINE START FUNCTION
Check that engine can be started with Intelligent Key carried and inserted into the key slot respectively.
Engine can be started.>>GO TO 10.
Engine cannot be started.>>Inspect Trouble Diagnosis Flow Chart for IVIS (NATS). Refer to BL-275, "
Trou-
ble Diagnoses Flow Chart for IVIS (NATS)" .
10. CHECK SECURITY INDICATOR FUNCTION
Check Security Indicator for lighting up under the two conditions below.
Security Indicator lights off when Push-button ignition switch is pushed with Intelligent Key inserted into or
pulled out of the key slot.
Security Indicator blinks when Intelligent Key is pulled out and Push-button ignition switch is in lock posi-
tion.
Lighting up condition is normal.>>Inspection END.
Lighting up condition is malfunctioning.>>Perform Security Indicator Inspection. Refer to BL-277, "
Check
