Suzuki DF 90 Service Manual

3-28 ENGINE CONTROL SYSTEM
NOTE:
• If more than two items fail at once, the self-diagnostic indication appears according to priority order. The
indication repeats three times.
• If the failed item remains, the self-diagnostic indication appears again after turning the ignition switch “ON”.
• After correcting failed item, the self-diagnostic indication appears until the ECM receives the proper signal
with the engine running.
• For cylinder temp. sensor, exhaust manifold temp. sensor or IAT sensor the self-diagnostic indication will be
canceled after corrective action by turning the ignition switch “ON”.
(The ECM will require 10 – 20 seconds after turning the ignition switch “ON” to cancel the self-diagnostic
indication.)
NOTE 1 :
The self-diagnostic indication may be canceled by turning ignition switch “ON” because the ECM detects only
battery voltage, not charging output. Under this condition the buzzer will not sound a 1-1 code.
However, if the rectifier & regulator have failed, the self-diagnostic indication will again appear after starting
the engine.
