CEL question.

On M104, pin #14, and 11 blinks.

Message: "Fuel safety shut-off signal to engine control module (N3/4) 23 18.0
Closed throttle recognition signal to engine control module (N3/4)".

Could this throw a CEL in the Cabriolet? The CEL will not go away even after clearing codes AND disconnecting the battery.

Did you replace the ETA yet?

 

[Trae]

I'll have to look in the records, but I can't remember it being replaced.

Its the cabriolet that you saw with Klink.

Runs great however. I thought the CEL was only related to emissions.

Trae, you have to check codes on pin #3 (DM) of your Cabrio, this will tell you what is triggering the CEL. It's possible the DM itself has failed... not likely, but possible. I had that on one of my cars. Based on what you describe, you may find code #16 on the DM / pin 3.

See page 4 of this PDF:

Fuel safety shutoff is a certain limp-home mode that is triggered whenever something severe is odd with the the electronic throttle system on HFM, LH and ME Systems. Its there for a reason, so the ETA for instance can not accelerate the engine over a certain RPM itself.
I'd check the ETA/Electronic Throttle system as a whole, they go bad on the M104 just like they do on the M119s....

OK, #3 pin shows only 4 blinks that I read by depressing the button just below pin 3.

(The banana plug on pin 1 was too large to allow my blink code reader to plug into pin 3.)

Attempted to clear code, but it would not clear. Guess they are serious about the environment.

Here is the message: "Air injection inoperative".

Trae - Did you root cause code 4 on your cabrio?
