Using scan tool, read and record Sentry Key Immobilizer Module (SKIM) Diagnostic Trouble Codes (DTC). Erase SKIM DTCs. Turn ignition off, then back to RUN position several times, leaving ignition in on position for a minimum of 30 seconds per cycle. Recheck for DTC. If DTC resets, replace SKIM. See SENTRY KEY IMMOBILIZER MODULE  under REMOVAL & INSTALLATION. Perform POWERTRAIN VERIFICATION TEST  under VERIFICATION TESTS. If DTC does not reset, test is complete.
