Suzuki DF150 Service Manual page 98

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:
This self-diagnostic indication may not display (be canceled) by turning the 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.
NOTE 2:
The diagnostic code for model discrimination is displayed when a failure (either open or short circuit) exists
in No.13 terminal of the wiring harness/connector.
When this code is displayed, the first check should be for a failure in the wiring harness.
When this code is displayed, do not replace the ECM.
Replacing the ECM may cause improper execution of the self-diagnostic for model discrimination
possibly leading to engine trouble.
