** SOLUTION **
Cause

An aftermarket device improperly installed on the data link can cause a
variety of symptoms. Various Data Link codes can be generated from any
modules connected to the affected circuit. In addition, interference can
create a variety of physical symptoms that may or may not seem to be
related. Some examples are intermittent loss of throttle, incorrect or no
readings from instrument cluster gauges, regeneration failure, and derate.
Recent models of third party devices in many cases utilize either a "T" or "Y"
connector that connects to the OEM Diagnostic connector, or will place the
module in-line so the diagnostic connector mounted to the dash is in fact a
diagnostic connector from the third party device. A diagram showing these
two situations can be seen below:
