CHECKING TROUBLE CODES
The blinking red LED light on the ECU displays trouble
codes. Its sequence indicates a particular system
malfunction by blinking as many times as the first digit of a
trouble code, pausing, and then blinking as many times as
the second digit of a trouble code.
For example, the red LED will indicate low fuel pressure
(27) by blinking twice, pausing, and blinking seven more
times.
IMPORTANT: Be aware that more than one trouble code
may be present.
A blinking green LED indicates the ECU processor is
operating correctly, even if a sub-component of the ECU
(e.g.: barometric pressure sensor) has failed. A constant
illuminated green (not blinking) LED indicates the ECU may
be experiencing a low battery voltage condition or need
replacement. See EFI Trouble Code Identification on
page 60.
Visually inspect the red LED to verify trouble codes.
To read trouble codes more easily, place a mirror under the
ECU to view LED reflection.
IMPORTANT: If no trouble code is present, but engine is
not operating normally, See Diagnostics for Non-Trouble
Codes on page 64.
TROUBLE CODE DIAGNOSTICS
NOTICE: Before performing diagnostic tasks, be aware of
the screw on the bottom of the throttle body that adjusts the
servo offset. The servo offset calibrates the throttle body at
the factory using a flow bench and should NEVER be
touched. If it is tampered with, the engine will run poorly
and void the warranty. See Figure 155.
Code 16: Low Battery Voltage
1. Charge the battery. Refer to Operator’s Manual.
2. Start the engine. Refer to Operator’s Manual.
3. Check charging system at the battery.
a. With a multi-meter set to volts DC, back probe the
battery terminals. At full throttle (3600 RPM), the
reading should be 7.5 – 8.4 volts DC.
If voltage measures less than 7.5 volts, check charging
system at the engine. Advance to step 5.
IMPORTANT: If the engine is cold, it is normal for the
engine speed to be 100 – 200 RPM higher until operating
temperature is reached.
4. Stop the engine. Refer to Operator’s Manual.
b. Check the battery. With the engine off, the battery
voltage should be 7.2 – 8.4 volts DC. See Figure 156.
If voltage measures less than 7.2 volts after charging,
replace battery.
