General Information

The theft deterrent controller module can command the instrument cluster to illuminate the SECURITY indicator only when the ignition key is in the ON position. If the PCM loses communication with the theft deterrent controller module, the instrument cluster will also detect the loss of communication and will illuminate the SECURITY indicator. The SECURITY indicator can indicate both malfunctions (Indicator on steady) and tamper (Indicator flashing - indicating unauthorized operation). Under the following conditions the SECURITY indicator may be commanded to illuminate.
