Section 18.4
Code Descriptions
To read codes, use the DDR or press and hold the Diagnostic Request Switch with the ignition ON, engine at idle or not running. Active codes will be flashed on the SEL/RSL. Inactive codes will be flashed on the CEL/AWL. The cycle will repeat until the operator releases the diagnostic request switch. Flash codes, descriptions, and SAE faults are listed in the following chart..
