Sounds to me like the tech who repaired your car just guessed at the faulty component.

It's no coincidence that the battery died and then the VSA-related indicator lights illuminated.

Low battery voltage will cause the following VSA DTC's to be set by the VSA modulator-control unit:

DTC 61-01: VSA Modulator-control Unit Initial IG Low Voltage
DTC 61-21: VSA Modulator-control Unit Power Source Low Voltage 1
DTC 61-22: VSA Modulator-control Unit Power Source Low Voltage 2
DTC 61-23: VSA Modulator-control Unit Power Source Low Voltage 3

Remedy: either charge (if it can be charged successfully) or replace the battery, then have the dealer clear the VSA DTC's (because the average, generic scan tool will not be able to access the VSA modulator-contol unit memory).

The battery is testing fine and shows 12 volts when the car is off. When the car is on it is showing 14.1 volts. The errors you are quoting are the errors that the service tech got when he pulled the codes.

How do you suggest charging the battery? Trickle charger or regular charger?

Well, based on the voltages you obtained, the battery has already been charged --- by the alternator.

Problem is, those codes are retained in the VSA modulator-control unit memory until they are cleared with an HDS. So, although your battery is now sufficienty charged and outputing an adequate source voltage to the VSA modultor-control unit, those codes will not disappear until cleared by the HDS.

Yes, most generic scan tools may be able to reset the ECM (engine control module), but they may not be able to access the memory of the VSA modulator-control unit. Or, they may be able to access the memory, but they may not be able to reset it.

Have you already tried clearing the ABS DTC's?
