ELECTRICALS 52 or interfering with adjacent or surrounding parts in all steering positions. l When using the Service Tester, follow the manufacturers instructions. l Always insert the probe of the tester from the wire harness side. l Make sure to use the probe with a tapered tip. l Do not drop parts. GUIDELINES l Verify the Complaint. Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area. l Analyze the Schematic Look up the schematic for the problem circuit. Determine how the circuit is supposed to work by tracing the current paths from the power feed through the circuit components to ground. If several circuit fail at the same time, the fuse or ground is a likely cause. Based on the symptoms and your understanding of the circuit operation, identify one or more possible causes of the problem. l Isolate the Problem by Testing the Circuit. Make circuit tests to check the diagnosis you made as above. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test for the most likely cause of failure first. Try to make tests at points that are easily accessible. l Fix the Problems Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures. l Make Sure the Circuit Works Turn on all components in the repaired circuit in all modes to make sure you have fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on that fuse. Make sure no new problem turn up and the original problem does not recur.
