Do not use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Do not repair, splice or modify the SRS wiring harness. If the harness is damaged, replace it with a
new one.
Keep ground portion clean.

The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-IlI are as follows:
