TO READ CODES: Use the diagnostic data reader or depress and hold the diagnostic
request switch with the ignition on, engine at idle or not running. Press and hold the switch.
Active codes will be flashed on the "Stop Engine" light (SEL) followed by the inactive codes
being flashed on the "Check Engine" Light (CEL). The cycle will repeat until the operator
releases the diagnostic request switch.
