   Is DTC 62-11 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting - Refer to:

   How to Troubleshoot the VSA System (2014 2015 2016) or

   If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the Freeze data/on-board snapshot.

2. VSA modulator-control unit check

   - 1. With the engine still running, check and note the parameter(s) below with the HDS.

   Signal	Current conditions
   	Values	Unit
   BATTERY VOLTAGE

   - 2. Using a voltmeter, measure and note the voltage across the battery terminals.

   NOTE:  If the voltage is more than 15. 1 V, troubleshoot the PGM-FI DTCs - Refer to:

   How to Troubleshoot the Fuel and Emissions Systems (2014-20) or

   How to Troubleshoot the Fuel and Emissions Systems (With Auto Idle Stop System) (2016-20)

   - 3. Compare the voltage noted in step 2-1 to the voltage in step 2-2.

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

   YES 

   Check the battery - Refer to:

   Battery Test (2014 2015)

   Battery Test (2016 2017 2018 2019 2020)

   , and check for any PGM-FI DTCs - Refer to:

   How to Troubleshoot the Fuel and Emissions Systems (2014-20) or

   How to Troubleshoot the Fuel and Emissions Systems (With Auto Idle Stop System) (2016-20)

   NO 

   Go to step 3.

3. VSA modulator-control unit check (update)

   - 1. Update the VSA modulator-control unit if it does not have the latest software.

   - 2. Turn the vehicle to the OFF (LOCK) mode.

   - 3. Start the engine.

   - 4. Check for DTCs with the HDS.

   Is DTC 62-11 indicated?

   YES 

   Check for loose terminals in the VSA modulator-control unit 38P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit .

   NO 

   Troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
