Subaru Impreza 3 / Impreza WRX / Impreza WRX STI. Service manual — part 368
GD(H4DOTC)-224
Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
5. DIAGNOSTIC METHOD
• Abnormality Judgment
At the main IC, check the sent signal at each timing which occurs immediately after the tumble generator
valve output is set to ON → OFF, and judge open NG when the open NG signal is sent 96 ms × 20 time(s)
in a row.
Time Needed for Diagnosis: 96 ms × 20 time(s)
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
• Normality Judgment
Judge as OK and clear the NG when the OK signal is sent.
Time Needed for Diagnosis: Less than 1 second

GENERAL DESCRIPTION
EF:DTC P2012 INTAKE MANIFOLD RUNNER CONTROL CIRCUIT LOW (BANK 2)
1. OUTLINE OF DIAGNOSIS
Detect the open or short circuit of tumble generator valve motor.
Judge as NG when the overcurrent signal is sent from IC after tumble generator valve driving IC diagnosis.

4. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously.
5. DIAGNOSTIC METHOD
• Abnormality Judgment
At the main IC, check the sent signal at each timing which occurs just before the tumble generator valve out-
put is set to ON → OFF, and judge open NG when the open NG signal is sent 96 ms × 10 time(s) in a row.
Time Needed for Diagnosis: 96 ms × 10 time(s)
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
• Normality Judgment
Judge as OK and clear the NG when the OK signal is sent.
Time Needed for Diagnosis: Less than 1 second
