Figure 5-1 Engine Error Indicator
The engine error indicator (1) flashes when the on-
board diagnostics detects an engine problem.
Certain engine problems can result in reduced engine
RPM, the engine shutting down, or the engine failing to
start.
Error Diagnostic Code Examples
The specific engine error can be determined based on
upon the number and duration of flashes displayed by
the engine error indicator.
Figure 5-2 shows three possible engine error code
examples. These examples correspond to the error
codes shown in the “Engine Diagnostic Codes Table”
on page 5-6“Engine Diagnostic Codes Table” on
page 5-6Engine Diagnostic Codes Table on the follow-
ing pages.
Note: As shown in Figure 5-2, a two-second “ignition
on” flash, followed by a three-second “separator
pause” before the error codes are displayed. Error
codes are then repeated, separated by additional three
second “separator pauses”.
Example 1: Indicates a throttle problem, possibly a
wiring error or a defective throttle lever sensor.
Example 2: Indicates an exhaust gas recirculation
problem, possibly wiring/connection problems, cold
starter solenoid valve or ECU errors.
Example 3: Indicates a combination of errors from
Examples 1 and 2.
