Does the ecm control charging system on a 93 jeep wrangler?

No, the ECM (Engine Control Module) in a 1993 Jeep Wrangler does *not* directly control the charging system. The charging system is regulated by the alternator and its internal voltage regulator. While the ECM might monitor battery voltage as part of its overall system checks, it doesn't actively control the alternator's output.
