A er the problem has been corrected, the fault codes may be cleared by following the ECU Reset and TPS Learn
Procedures.
The chart on the following page lists the fault codes, and what they correspond to. Following the chart is a list
of the individual codes with an explanation of what triggers them, what symptoms might be expected, and the
probable causes.
A MIL may not be provided with the engine. If the equipment manufacturer has not added a MIL to the
equipment, one can be added easily for quick diagnostics. The main engine to vehicle connection will have a tan
wire which is the ground for the MIL. Either incandescent or LED type bulbs can be used for the MIL as long
as they do not draw more than 0.1 amps. The bulb needs to be rated at 1.4 Wa s or less, or needs to have a total
resistance of 140 Ω or more. LEDs typically draw less than 0.03 amps. Attach +12 volts to the positive terminal of
the bulb and attach the ground terminal of the bulb to the tan wire.
