The Laser Air Bag Test Resistor Set is designed to aid in the diagnosis of airbag systems. It assists in identifying failures in the airbag unit, airbag clock spring, and seat-belt pre-tensioners. The tool functions as a 2.5-ohm resistor with two pin probes. By connecting it in place of the airbag unit, technicians can test the system and easily confirm component failure, leading to a quicker diagnosis of illuminated airbag warning lights. This set facilitates straightforward connection and provides efficient component failure diagnosis for repairs.
