Operation CHARM: Car repair manuals for everyone.

- When to Use These Charts


These diagnostic charts are used to find and repair problems that the on-car diagnostics found. They can be:

1. Charts which fix a problem when the on-car diagnostics won't work.

2. Charts where a stored trouble code leads to a particular problem.

3. Charts that are used because the Field Service Mode Check found a problem.

4. Engine Cranks But Won't Run charts.
