Retrieving Lamp Flash Codes (LFC)

The ECS monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the ECS will illuminate the air bag indicator located in the instrument cluster. When the ignition is cycled (turned off and then turned on), the air bag indicator will flash the two-digit Lamp Fault Code (LFC). The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The ECS will also communicate the current and historical DTCs through the Data Link Connector (DLC), using the New Generation STAR (NGS) Tester. If the air bag indicator does not function, and the system detects a fault condition, the ECS will activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime or buzzer is heard, the SRS or the air bag indicator requires service.

Lamp fault codes are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
