STEP 8. Check for open circuit and short circuit to ground
between intake manifold tuning solenoid connector B-49
(terminal No. 2) and ECM connector C-51 (terminal No. 32)
<M/T> or PCM connector C-55 (terminal No. 53) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 12.
NO : Repair it. Then go to Step 12.
