2. Turn the ignition switch ON (II). The SRS indicator light comes on for about six seconds and then goes off. Then it will indicate the DTC:
- The DTC consists of a main code and a sub-code.
- Including the most recent problem, up to three different malfunctions can be indicated.

Examples Of DTC Indications:

- In case of a continuous failure, the DTC will be indicated repeatedly (see example 1).






- In case of an intermittent failure, the SRS indicator light will indicate the DTC one time, then it will stay on (see example 2).
- If both a continuous and an intermittent failure occur, both DTCs will be indicated as continuous failures.






- In case the system is normal (no DTC), the SRS indicator light will stay on (see example 3).
