CAUTION:
Do not use electrical test equipment on any circuit related to the SRS unless instructed. SRS wiring harnesses are covered with yellow insulation Just before the harness connectors 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:

DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using the "AIR BAG" warning lamp and/or CONSULT. 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.

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


HOW TO CHANGE SELF DIAGNOSIS MODE WITHOUT CONSULT

Air Bag Warning Lamp:

From User Mode to Diagnosis Mode
Diagnosis mode activates only when a malfunction is detected, by pressing the driver's door switch at least 5 times within 7 seconds after turning the ignition "ON". SRS will not enter Diagnosis mode, if no malfunction is detected.

From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition "OFF" for at least one second, then back "ON". Diagnosis mode is returned to the User mode. If switching Diagnosis mode to User mode is required while malfunction is being detected, switch the ignition "OFF", then back "ON" and press the driver's door switch at least 5 times within 7 seconds.
