  17. Following manufacturer's instructions, connect Tech II scan tool. Turn ignition switch to ON position. Select POWERTRAIN SPECIAL FUNCTIONS, then OUTPUT CONTROLS for CRUISE INHIBIT. While observing INHIBIT ENABLE LED on cruise control tester, command scan tool to enable cruise control. If INHIBIT ENABLE LED dimmed, go to next step. If LED did not dim, go to step  33.
  18. Turn ignition switch to OFF position. Disconnect cruise control tester and reconnect wiring harness to cruise control module. Road test vehicle at speeds greater than 25 MPH. Operate cruise control system. Using scan tool. observe CRUISE INHIBIT status. If scan tool displays ENABLED, go to next step. If scan tool does not display ENABLED, go to ON-BOARD DIAGNOSTIC II (OBD-II) SYSTEM CHECK in SELF-DIAGNOSTICS - INTRODUCTION article in ENGINE PERFORMANCE.
