On Board Diagnosis LogicBBS005CR
The MI will not light up for this diagnosis.
FAIL-SAFE MODE
ECM enters in fail-safe mode when the malfunction is detected.
DTC Confirmation ProcedureBBS005CS
CAUTION:
Always drive at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.
3. Maintain the following conditions for at least 6 consecutive sec-
onds.
Hold the accelerator pedal as steady as possible.
4. Stop vehicle with engine running and let engine idle for 10 seconds.
5. If 1st trip DTC is detected, go to EC-121, "
Diagnostic Procedure" .
If 1st trip DTC is not detected, go to next step.
6. Maintain the following conditions for at least 20 consecutive seconds.

Overall Function CheckBBS005CT
Use this procedure to check the overall function of the intake valve timing control system. During this check, a
1st trip DTC might not be confirmed.
WITHOUT CONSULT-II
1. Start engine and warm it up to the normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Set the tester probe between ECM terminal 62 (IVT control solenoid valve signal) and ground.
5. Start engine and let it idle.
6. Check the voltage under the following conditions.
Verify that the oscilloscope screen shows the signal wave as
shown below.
