Engine Controls Diagnostic Information

The Engine Controls Diagnostic Information and Procedures consist of diagnostic tables and functional checks that are developed in order to locate a faulty circuit, component, or system through a logical process of elimination. The diagnostic tables are prepared with assumption that the vehicle functioned correctly at the time of assembly and that there are not multiple malfunctions present.
