  1. Wait for 15 seconds or more.
  2. Compare the voltage noted in step 2 to the voltage in step 3.

Is the difference between the two voltage readings less than 3 V?

YES

Check the 12V battery, and check the PGM-FI DTCs - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the CVT System (CVT).

NO

Go to step 4.

4. VSA modulator-control unit check (update):
