transient in nature, which means they happen, throw the ski into Limp Mode, and go away just as

and there are no active faults.
You see this often on the various Sea Doo forums. Someone posts they have a problem with the
ski going into limp mode, and they bring it into their local dealer, only to be told "there are no
faults". This is only partially true; there may not be any active faults, but there always is evidence
that a fault had happened before. It is all logged in the fault table.
Example 2:
Let's suppose that the rider in the above example hit the wake, and the connector actually fell off
the Exhaust Temperature Sensor. In this case, if you read the ski anytime after it happened, the
state of the ETS fault would be Active. In this example, you can quickly zero in on the problem and
fix it. Unfortunately, this type of problem is the exception rather than the rule. Most difficult
troubleshooting on the DI involves transient faults. They are not presently active, so how do you
figure out what it is? The answer is in the Count column.
The Count Column
Anytime a fault is triggered and the ski lights the Maint light and/or goes into Limp Mode, the fault is
logged in the Count column for that particular fault. This provides the evidence you need to zero in
on the problem. However, there is a major issue, a problem that makes it very difficult for the
typical dealer technician to zero in on the problem. The following screen illustrates the problem:
