Suzuki AN400 - DTC Table; Fail-Safe Function Table

1A-11 Engine General Information and Diagnosis:
DTC Table
B705H11104009
In the LCD (DISPLAY) panel, the malfunction code is indicated from small code to large code.
*1
To get the proper signal from the throttle position sensor, the sensor basic position is indicated in the LCD (DISPLAY)
panel. The malfunction code is indicated in three digits. In front of the three digits, a line appears in any of the three
positions, upper, middle or lower line. If the indication is upper or lower line when engine rpm is 1 450 r/min, slightly
turn the throttle position sensor and bring the line to the middle.
Fail-Safe Function Table
B705H11104010
FI system is provided with fail-safe function to allow the engine to start and the motorcycle to run in a minimum
performance necessary even under malfunction condition.
The engine can start and can run even if the signal in the table is not received from each sensor. But, the engine
running condition is not complete, providing only emergency help (by fail-safe circuit). In this case, it is necessary to
bring the motorcycle to the workshop for complete repair.
