17. Prove out the SRS as follows:

Turn the ignition key from ON to OFF. Wait10 seconds, then turn the key back to ON andvisually monitor the air bag indicator with theair bag modules installed. The air bag indicatorwill light continuously for approximately 6seconds and then turn off. If an air bag SRSfault is present, the air bag indicator will:

- fail to light.

- remain lit continuously.

- flash.

The flashing might not occur untilapproximately 30 seconds after the ignitionswitch has been turned from the OFF to the ONposition. This is the time required for therestraints control module (RCM) to completethe testing of the SRS. If the air bag indicatoris inoperative and a SRS fault exists, a chimewill sound in a pattern of 5 sets of 5 beeps. Ifthis occurs, the air bag indicator and any SRSfault discovered must be diagnosed andrepaired.

Clear all continuous DTCs from the RCM usinga diagnostic tool.
