- Hold the sides of the connector, push in tabs and pull out the
tube.
- If quick connector and tube on fuel pump assembly are stuck,
push and pull several times until they move. Disconnect them
by pulling.
CAUTION:
The tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
Do not use any tools to remove the quick connector.
Keep resin tube away from heat. Be especially careful
when welding near the resin tube.
Prevent acid liquid such as battery electrolyte, from get-
ting on resin tube.
Do not bend or twist resin tube during installation and removal.
To keep the connecting portion clean, free of foreign
materials and to avoid damage, cover them completely
with plastic bags or something similar.

CAUTION:
Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness con-
nectors.
Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace it
with a new one.
Keep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-III.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-III are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
