Using SECURITY Indicator

  1. Turn ignition switch to RUN position to deactivate Content Theft Deterrent (CTD) alarm system (if equipped). Turn ignition switch to OFF position. Remove RADIO fuse No. 17 (15-amp) from instrument panel fuse block. See Figure . RADIO fuse is located in lower right corner of instrument panel fuse block.
  2. Turn ignition switch to ACC position. Chime will sound 1-2 times to verify system has entered programming mode for customizing special features. Within 5 seconds, turn ignition switch to OFF position, then immediately back to ACC position. Chime will sound 3 times to verify diagnostic mode has now been entered. If chime does not sound 3 times, diagnostic mode has not been entered. Perform TEST C: CANNOT ENTER BODY CONTROL MODULE DIAGNOSTICS under SYSTEM TESTS in BODY CONTROL MODULES - CAMARO & FIREBIRD article.
  3. BCM will start to flash DTCs on SECURITY indicator 4 seconds after entering diagnostic mode. Each flash of indicator represents a number. For example, one flash followed by 2 quick flashes represents DTC 12. DTC 12 will always be the first DTC displayed, indicating diagnostic mode is at beginning of DTC display. Last DTC to be displayed will be DTC 55 followed by hardware configuration, then software configuration. Each DTC is displayed 3 times before next DTC is displayed.
  4. If more than one DTC is present, DTCs will display beginning with lowest current DTC to highest current DTC, followed by lowest history DTC to highest history DTC. Remote transmitter DTCs 41-45 will then be displayed if invoked while in diagnostic mode. DTCs will cycle sequentially until diagnostic mode is exited. To exit diagnostic mode, turn ignition switch to OFF position, and install RADIO fuse.
