Training Solutions for the New ASE L4 Exam

What is the ASE L4 Exam?

The Advanced Driver Assistance Systems (ADAS) Specialist Test (L4) is a new certification from the National Institute of Automotive Service Excellence (ASE). It is geared toward technicians who diagnose, repair, and calibrate advanced driver assistance systems in modern automobiles and light trucks.

Diagnosis and Maintenance of a High Voltage Battery

The L4 exam will be a challenging evaluation of knowledge and abilities with a prerequisite; students must have passed either the Automobile: Electrical/Electronic Systems (A6) certification test or the Collision: Mechanical or the Electrical Components (B5) certification test.

Content Areas Include:

  1. General ADAS Service and Diagnosis
  2. Camera-Based Systems Service and Diagnosis
  3. RADAR-Based Systems Service and Diagnosis
  4. Ultrasonic (Sonar)-Based Systems Service and Diagnosis

Training Solutions

With the new skills required comes the need for the latest training tools. Lucas-Nuelle has developed an extensive learning system with seven modules to prepare students for a successful automotive career.

Introduction to LIDAR (Light Detection and Ranging)

Use this training system to teach diagnostic skills, including optical distance and speed measurement. The hardware is based on a real, industry-standard LIDAR module, giving trainees valuable insights into how the system works.

When combined with our e-learning course, the system not only teaches how the system functions but also how to demonstrate troubleshooting techniques.

A. General ADAS Service and Diagnosis

  1. Inspect for damaged, missing, obstructed, modified, customized, inoperative, previously repaired or add–on vehicle components that could affect the performance of an ADAS system (including the use of non–factory specified components).
  2. Determine the repairability of body components that would affect the operation of an ADAS component.
  3. Determine the repairability of damaged components and related mounting locations.
  4. Research applicable vehicle and service information, such as vehicle service history, service precautions, technical service bulletins, and service campaigns/recalls.
  5. Research and identify ADAS intersystem design/configuration action with other vehicle systems (i.e., Braking, Steering, Powertrain, Active Suspension, Restraints, and TPMS).
  6. Verify vehicle concerns and/or conduct a pre-scan; determine vehicle equipment/options.
