2006 9400i fault code 128:F13 PID 027?

We see this all the time. The LCD display was never designed to properly display fault codes. It is not meant to be a code reader. It does not display codes properly and will display codes with errors which can send you on a wild goose hunt. You should only be trouble shooting problems when you have either the WARN engine or ABS warning lights on with the proper scan tool plugged in.

The numbers displayed really aren't much help. The numbers are more of a message, not really a fault code. The 128 is an address for the engine. F13 is simply the number of messages. PID 027 is parameter id of the suspect failed part, but this is only partial information and this is what is commonly incorrect.

 

Chances are the wiring is rubbed through somewhere and is just at the point of being fully broken. The temps is causing contraction in the wiring which is causing intermittent circuit interruptions. 90% of the time the harness is rubbed through somewhere over the rocker cover area/fire wall area if you have an ISX.

 

One of the reasons I used a Scangauge on my 2006 9400i (and my present 2013 FL). It actually gave me the real codes and I could even clear the minor ones. Most get the Scangauge for all the other goodies like average mpg, boost, cost per mile on fuel, and a host of other features, but it also allows pulling up codes and dealing with them.

Yes, absolutely. Anything that communicates on that datalink can contribute to corruption. If you have a satellite, driver information display or even the boost gauge on some trucks is actually a datalink driven gauge. Datalinks can be a real pita to troubleshoot because they tie into so much. An actual wire problem is the more likely culprit. When inspecting the wiring, also focus on areas where the loom is tight or contacting another surface. The plastic the loom is made of becomes very hard to the point it will saw right through the wiring inside of it. The loom will look fine on the outside, but the wiring will be damaged on the inside. Fun eh?
