I have a diagnostic reading from Durametric. I keep getting the following code, which I can't clear.

C418:

U0418 - CAN fault, brake

What does this code mean and does anybody know what the fix is for this fault?

Thanks,

Hello

I have the same C418 - CAN fault brake Error Code (997.2 Turbo). Did you get a solution?

From the 2006 997 DME Diagnosis manual:

U0418

Fault entry in specified control module

Note!
Internal function test completed.

Diagnostic conditions
The control module initially tests internal function sequences after wake-up. If they are OK, all diagnosable outputs are then tested and any faults are stored.
Control module wake-up through:

• event-induced CAN message
• wake-up signal via wake-up line
• key contact (terminal S)
• "Ignition on"

Possible fault causes

• Control module is incorrectly coded
• Periphery connected to specified control module is incorrect
• Control module faulty (in most cases the cause is not the control module but incorrect coding!)

Fault effects

• The specified control module sends only substitute values via the CAN.
• Other control modules detect these substitute values and set this fault code

Many thanks! But, what's the solution ....software update? New modul?

Do you know?

No idea. But start with the basics.

1. What module is showing this error in Durametric? Ties to the "Fault entry in specified control module" piece.
2. Did anything change recently with the car, or related to that module?
3. Any recent changes with the coding in Durametric? The notes above keep saying coding issues.

I've screwed around with Durametric coding in the past and had some weird messages show up, mostly for things like telling one module something is installed but a different module thinks it's not installed, stuff like that.
