Diagnostic Procedure Initial Steps

DIAGNOSTIC PROCEDURES - INITIAL STEPS

FOLLOW THESE STEPS WHEN BEGINNING ANY SRS SERVICE:

1. Check the SRS fuses (multi-purpose fuses No.11 and No.18). If either is loose, tighten it; if damaged or blown, replace it.

2. After performing step 1, start engine. Does "SRS" warning light illuminate for about 7 seconds and then turn OFF? If yes, SRS system is functioning properly. If no, continue with following steps.

NOTE

The SRS warning light will light even when the battery voltage drops. In this case, the SRS warning light will go out when the battery voltage is restored to the normal value.

3. Turn the ignition key to the "LOCK" position.

4. Connect the Scan tool to the data link connector located at the right side of the junction block.

Caution

Turn off the ignition switch before disconnecting or connecting the scan tool.

5. If the scan tool cannot communicate with any of the system, perform TEST 1.

6. Start the SRS diagnosis, by conducting TEST 2 (SRS warning light does not extinguish) or TEST 3 (SRS warning light does not illuminate.) which begins on next page.
