CeRR Overview of the Task List Suspension and Steering (Test A4) The following section includes the task areas and task lists for this test and a written overview of the topics covered in the test. The task list describes the actual work you should be able to do as a technician that you will be tested on by the ASE. This is your key to the test and you should review this section carefully. We have based our sample test and additional questions upon these tasks. The overview section will also support your understanding of the task list. ASE advises that the questions on the test may not equal the number of tasks listed; the task lists tell you what ASE expects you to know how to do and be ready to be tested upon. At the end of each question in the Sample Test and Additional Test Questions sections, a letter and number will be used as a reference back to this section for additional study. Note the following example: A.3.1 A. Steering Systems Diagnosis and Repair (10 Questions) Task A.3 Steering Linkage (3 Questions) Task A.3.1 Inspect and adjust (where applicable) front and rear steering linkage geometry (including parallelism and vehicle ride height) Example: Rack-and-pinion steering unit 1.

Damage to the column or column bearings can result. Disconnect the wiring harness, bottom steering coupler retaining bolt, and transmission linkage from the column. Mark the position ofthe steering column coupler to the steering gear. Remove, if necessary, any dash trim to gain access to the steering column mount under the dashboard. Carefully remove the steering column from the vehicle. Inspect all external components including the flex coupler and lower column U-joint (if equipped). Many vehicles are designed with an intermediate shaft containing two U-joints. Inspect the U-joints for wear, looseness and binding. Disassembly of the steering column will be necessary to inspect internal components of the column. Task A.1.3 Disarm, enable, and properly handle airbag system components during vehicle service following manufacturers? procedures. Inflator module Combination Ignition switch lock cylinder Steering wheel Steering shaft The supplemental inflatable restraint system (air bag) must be disarmed properly before any work is performed on the steering column. Failure to disarm the air bag may result in the accidental deployment of the air bag, which can cause personal injury and unnecessary repairs to the air bag system. Always consult the service manual for recommended procedures on disabling the air bag system. The following is a list of basic procedures and precautions that should be followed when working with and around air bag systems. Always disable the air bag system before servicing the air bag or any components near or around the steering column and/or air bag system. Never subject the inflator module to temperatures greater than 175°F (79.4°C). If any air bag component is dropped, it should be replaced. Never test any air bag component with electrical test equipment unless instructed to do so by the factory service manual. When carrying a live (not deployed) air bag, always point the bag and trim cover away from you. When placing a live air bag on a workbench, always face the air bag and trim cover up. Discarded live air bags must be deployed. Follow manufacturer?s procedure for proper disposal. Lock the steering wheel in place whenever removing the steering wheel, steering column, or steering gear to prevent damage to the clock spring. The clock spring maintains a continuous controller.
