In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Qualifying learners are able to use technical literature and information systems to assist them in following electrical circuits/systems in a vehicle, identifying and locating electrical components in these circuits or systems and, where applicable, obtaining further information on the purpose, functioning and testing of these systems. This knowledge and skills should empower them to understand a broad range of basic automotive electrical systems including, but not limited to, lighting, signaling, instrumentation, ventilation and similar fundamental circuits. It also provides foundational competence for further unit standards in autotronics both at this and higher levels.

Learners credited with this standard will be able to:
  • Demonstrate the ability to locate technical information in an auto electrical (autotronics) context.
  • Use technical information to locate, remove and test auto electrical devices and components.
  • Differentiate between the wiring harnesses on a vehicle.
  • Locate joints and earth points in the various harnesses. 
    		•

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
