Usage:
On the pages that follow are two lists of possible problems, Diagnosed Problems List and Undiagnosed Problems List. Before checking the list of problems, check the SCM display for any diagnostic codes. These codes aid in finding the problem (see Diagnosed Problems List).
Before replacing anything, inspect all control, component and harness connections. Loose connections could cause electrical problems. Make sure the connections are tight before testing continues.
Identify your particular type of problem from the Problem List, then go directly to that problem procedure. However, when you begin the procedure for that problem, start at Step 1 and follow through the step by step procedure. The steps in a particular problem provide a definite sequence to be followed for a logical, one by one elimination of many variables. These steps are arranged in order from the more probable/easiest to check, to the less probable/more complex to check.
When the cause of the problem is found and corrected, stop the test. Do not continue through the complete procedure just because it is there.
