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.
