Land Rover Defender: How To Use Diagnosis and Testing Procedures
Inspection and Verification
Visual Inspection Charts, Symptom Charts and other information charts (such as diagnostic routines) or supplement test procedures with technical specifications will navigate the user to a specific test procedure.
Symptom Chart
The symptom chart indicates symptoms, sources and actions to address a condition.
Pinpoint Tests
For electrical systems, pinpoint test steps are used to identify the source of a concern in a logical, step-by-step manner. Pinpoint tests have two columns: CONDITIONS and DETAILS/RESULTS/ACTIONS.
The CONDITIONS column is used exclusively for graphics and icons (with or without captions) and the DETAILS /RESULTS/ACTIONS column provides direction to another test step or specific corrective actions.
The boxed numbers indicate the order in which the described action is to be carried out.
Component Tests
A component test is used when a component is tested in multiple pinpoint tests, or if a procedure is too complicated to be formatted within a single page of the pinpoint test.
Illustrations
Test illustrations show the measurement or test to be carried out in a test step.
A representative tester graphic is used for voltmeters and ohmmeters.
If multiple measurements are made in a single graphic, the test leads are drawn with a solid line until the test lead splits to indicate the multiple measurements, at which point dashed lines are used.
Breakout box type testers are represented by a double circle test pin. Test pins are labeled with the pin number.
