DTC Table
B931H21104006
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 difgits. In front of three digits, a line appears in any of the position,
upper, middle or lower line. If the indication is upper or lower line when engine rpm is 1 500 rpm, slightly turn the
throttle position sensor and bring the line to middle.
In the normal condition, the throttle valve stop screw pushes throttle valves slightly, and indication point is middle line.
Fail-Safe Function Table
B931H21104007
FI system is provided with fail-safe function to allow the engine to start and the vehicle to run in a minimum
performance necessary even under malfunction condition.
The engine can start and can run even if the above signal 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
vehicle to the workshop for complete repair.
