Self-Diagnostic System; Priority/Code/Pattern For Self-Diagnostic System Operation - Suzuki DF200 Service Manual

SELF-DIAGNOSTIC SYSTEM

The self-diagnostic system alerts the operator when an abnor-
mality occurs in a signal from sensor, switch, etc.
When the system is activated, the "CHECK ENGINE" lamp
flashes (lights intermittently) according to each code pattern
along with a buzzer sound.
When engine is running, the buzzer sounds a series of short
(0.2 sec) beeps.
When engine is not running, the buzzer sounds according to
each code pattern, but not simultaneous with the lamp flash.
The buzzer sound, activated by the self-diagnostic system, can
be temporally canceled by pushing the ignition key in.
