Without Scan Tool

Without Scan Tool (SRS Indicator Lamp)


Special Tools Required: SCS Service Connector

Service Check Connector:

1. Turn the ignition switch OFF, and wait for ten seconds. Then connect the SCS service connector to the service check connector (2P). If you do not wait ten seconds, the SRS unit will not be completely reset and will not output DTCs.
2. Turn the ignition switch ON (II). The SRS indicator light comes on for about six seconds and 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 fig).
- In case of an intermittent failure, the SRS indicator light will indicate the DTC one time, then it will stay on (see example 2 in fig).
- 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 in fig).

3. Read the DTC.
4. Turn the ignition switch OFF, and wait for ten seconds. Then disconnect the SCS service connector from the service check connector (2P).
