Without Scan Tool

CAUTION:
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses (except "SEAT BELT PRE-TENSIONER" connector) are covered with yellow insulation either just before the harness connectors or for the complete harness, for easy identification.

Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged, replace it with a new one.

Keep ground portion clean.




DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using "AIR BAG" warning lamp, "SEAT BELT" warning lamp and/or CONSULT-II. The reading of these results is accomplished using one of two modes -"User mode" and "Diagnosis mode".

The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system malfunction through the operation of the "AIR BAG" warning lamp and/or "SEAT BELT" warning lamp.

The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.

HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II




From User Mode to Diagnosis Mode
Diagnosis mode is activated by pressing the front door switch LH at least 5 times within 7 seconds after turning the ignition switch ON. If no malfunction is detected, SRS will not enter Diagnosis mode.

From Diagnosis Mode to User Mode
To return to User mode while a malfunction is being detected, turn ignition switch OFF, then back ON and press the front door switch LH at least 5 times within 7 seconds.

After a malfunction is repaired, turn ignition switch OFF for at least one second, then back ON. Diagnosis mode returns to User mode.

Checking Air Bag Operation by Using "AIR BAG" Warning Lamp - User Mode




1. After turning ignition switch from "OFF" to "ON", "AIR BAG" warning lamp operates.




2. Compare "AIR BAG" warning lamp operation to the chart.

NOTE: If "AIR BAG" warning lamp operates differently from the operations shown above, refer to "DIAGNOSTIC PROCEDURE 6" Diagnostic Procedure 6.
