Using The Tool - Laser 6323 Manual Del Usuario

Introduction
This tool is used to assist in the diagnosis of an airbag light being
constantly on. Thus it assists in the diagnosis of a failed airbag unit,
failed airbag clock spring, seat-belt pre-tensioners, etc.
New Airbag MoT Legislation
In the UK, new legislation came into force on March 20th 2013 meaning
that MoTs become stricter in relation to airbags. From this date all
airbag warning lights (SRS malfunction warning lights) on the dashboard
must light up when the ignition is turned on and must go out once the
car is started. If the SRS malfunction warning light indicates a system
malfunction then the vehicle will fail the MoT test.

Using the Tool

The tool is a 2.5 ohms resistor with two pin probes and when connected
to the associated wiring effectively becomes a "dummy" airbag, and
allows the vehicle's diagnostic system to identify the fault. It is used in
conjunction with a suitable code reader.

Using the Tool
The set consists of the resistor unit, plus a positive (red) and a negative
(black) pin probe. They are connected together via the 4mm 'banana'
type connectors. This type of connector means that the two pin probes
can also be connected to a suitably equipped multimeter for further
testing and diagnosis.
As an example of one of the many ways the tool can be used to
diagnose faults in the airbag system:
• Airbag warning light is ON (airbags have not been deployed).
• Fault codes indicate airbag circuit fault.
• Remove airbag (refer to warning section below before removing
airbag).
• Place pin probes onto airbag terminal connectors (terminal on steering
column). Position of positive or negative probes is not important.
• Switch on ignition and allow diagnostic system to go through the self-
check procedure.
• If airbag warning light goes out, then the diagnostic test has shown
that the airbag itself is faulty.
• If airbag warning light is still illuminated, then further diagnosis is
required (wiring, connectors, or other airbag system components).
Caution
• The resistance for the air bag circuits are 2.5 ohms; some other
circuits may vary so this tool is for main airbag circuit testing.
• Wear eye and hand protection when using the pin probes, they are
extremely sharp. Always replace the plastic covers over the pin probes
when not in use.
