- Read diagnostic codes by noting number of AIR BAG warning light flashes. A long flash (1.2 seconds) indicates a 10, and a short flash (0.3 second) indicates a one. For example, a long flash followed by 2 short flashes would indicate Code 12. Code will be displayed 3 times, with a 1.5-second pause between codes. Read and record codes. Turn ignition off, remove diagnostic terminal, and perform appropriate test. See AIR BAG CODE IDENTIFICATION
table.
