Entering On-Board Diagnostics: Notes

NOTE: Although other scan testers are available, manufacturer recommends using Diagnostic Readout Box (DRB) to diagnose system. Malfunction Indicator Light (MIL) function can be used, but it has limited diagnostic abilities.

NOTE: If trouble code exists that is not related to cruise control system, see TESTS W/CODES - 3.0L article in the ENGINE PERFORMANCE.
