DTC Troubleshooting (cont'd)
20. Update the VSA modulator-control unit if it does
not have the latest software (see page 19-140). If
the unit already has the latest software, substitute a
known-good VSA modulator-control unit (see page
19-141).
21. Test-drive the vehicle. Drive the vehicle at 7 mph
(10 km/h) or more.
NOTE: Drive the vehicle on a straight section of
road, not on a lift.
22. Check for DTCs with the HDS.
Is DT C 68-21 indicated?

modulator-control unit 36P connector. If the VSA
modulator-control unit was updated, substitute a
known-good VSA modulator-control unit (see page
19-141), then retest. If the VSA modulator-control
unit was substituted, go to step 1.
NO − If the VSA modulator-control unit was
updated, troubleshooting is complete. If the VSA
modulator-control unit was substituted, replace the
original VSA modulator-control unit (see page
