Hi Everyone,

 

I ran through the 'Engineering Test mode' and in the DTC (Diagnostic Trouble Code) history, it was listed C42400. I am looking for what this code corresponds to. I did a preliminary search online but did not find any leads. Where can I find the meaning of the code?

 

Thank you!

C42400 doesn't look like the proper format. I would expect something like C1029:00

I thought all Ford trouble codes started with P

Here is my understanding for how the code breakdown is..

 

First digit structure is as follows:

Pxxxx for powertrain

Bxxxx for body

Cxxxx for chassis

Uxxxx for future systems

 

Second digit structure is:

P0xxx Government required codes

P1xxx Manufacturer codes for additional emission system function; not

required but reported to the government

 

Third digit structure is:

Px1xx measurement of air and fuel

Px2xx measurement of air and fuel

Px3xx ignition system

Px4xx additional emission control

Px5xx speed and idle regulation

Px6xx computer and output signals

Px7xx transmission

Px8xx transmission

Px9xx control modules, input and output signals

 

The fourth and fifth digits designate the individual components and systems.

 

This may not be all inclusive but it is all I could find information on.

 

Tom

I just got Check Engine light up with C42400 code. Anyone (OP?) knows what it is? Just curious how urgent it is to call/visit the dealer. The symptom is that EV Now and EV Later mode get locked out and ICE comes on every 3-4 minutes for 10-15 seconds, regardless of power demand.

After the full day at the dealer today, the diagnosis is - a problem with the transmission coolant pump. The pump needs to be replaced, the car will be ready no earlier than EOD Monday. The car is 5 month old and has 6,100 km on it. I love driving this car, but not impressed with the "initial quality" at all!
