Good, the processors are getting power.
Upper LED does not turn on at all :
Either the
XDI200
is not rec12V power from pin (A), or the ECU has an
issue.
Engine cranking (below 400 rpm):
Lower LED changes color from red to green every other revolution:
Good, the crank sensor is working correctly
Lower LED does not change colors:
The crank sensor is not functioning properly (signal is not being picked up).
Engine running (over 400 rpm):
Lower LED is steady green:
Good, the crank trigger is functioning properly.
Lower LED flashes red every so often:
The
XDI200
is getting a bad signal from the crank trigger. The engine
most likely misfires whenever the light flashes red.
Engine is Hitting Rev Limiter:
Lower LED changes color turns orange:
The first or second stage of the rev limiter is occurring.
Lower LED turns red:
The third (and final) rev limiter stage is occurring.
Note:
If a misfire occurs during normal engine operation, but the lower LED on the
XDI200
was not
observed to momentarily flash red, the crank sensor may be at fault. To test for errors in this
situation, turn the engine off without removing power from the
XDI200
ECU by hitting the letter “K”
from the engine monitor screen when using a laptop). If the lower LED is flashing red after the
engine is shut off, there was a crank sensor problem at some point during the run.
9.2 Trouble Codes from the Check Engine Output
The trouble codes from the check engine output are related to the engine sensors. If the
check engine output wire is connected to a light bulb, it will display a sequence of flashes
depending on the problem. The diagnostic codes are arranged such that there are two digits for
each code. The check engine light will give long duration flashes for the first digit of the code and
short duration flashes for the second digit. Here are the diagnostic codes(asterisked items are
not available with the first software release):
12:
Crank Trigger Error
13:
Cam Trigger Error
14:
ECU Internal Failure*
21:
Throttle Position Sensor High
22:
Throttle Position Sensor Low
23:
Manifold Air Pressure Sensor High
24:
Manifold Air Pressure Sensor Low
25: Coolant Temperature Sensor High
26:
Coolant Temperature Sensor Low
31:
Manifold Air Temperature Sensor High
32:
Manifold Air Temperature Sensor Low
