Security Indicator Flashes Or Lights Solid Following Bulb Test

A security indicator that flashes following a successful bulb test indicates that an invalid key has been detected, or that a key-related fault has been set. A security indicator that lights solid following a successful bulb test indicates that the SKIM has detected a system malfunction or that the SKIS is inoperative. In either case, fault information will be stored in the SKIM memory. For retrieval of this fault information and further diagnosis of the SKIS, the PCI data bus, the SKIM message to the Central Timer Module (CTM) that control the security indicator, or the message inputs and outputs between the SKIM and the Powertrain Control Module (PCM), a DRBIII(R) scan tool and the appropriate diagnostic information are required. Following are preliminary troubleshooting guidelines to be followed during diagnosis using a DRBIII(R) scan tool:

1. Using the DRBIII(R) scan tool, read and record the faults as they exist in the SKIM when you first begin your diagnosis of the vehicle. It is important to document these faults because the SKIM does not differentiate between historical faults and active faults. If this problem turns out to be an intermittent condition, this information may become invaluable to your diagnosis.
2. Using the DRBIII(R) scan tool, erase all of the faults from the SKIM.
3. Cycle the ignition switch to the Off position, then back to the On position.
4. Using the DRBIII(R) scan tool, read any faults that are now present in the SKIM. These are the active faults.
5. Using this active fault information, refer to the proper procedure in the appropriate diagnostic information for the additional specific diagnostic steps.
