Engineering Mode Fault Codes

[Jon Hyde]

Hi All,

Having tried the method to access the Engineering Test Mode, provided by member AlexWard, I'm now a bit concerned since I get two reported faults:

ACC    - FAULT

ADCM - FAULT

Does anyone know what they might be?

Thanks in advance,
Jon

Phew!

Just discovered they're Adaptive Cruise Control & Adaptive Damping, neither of which I have.

Heartrate now stabilised!

I've also accessed the Engineering Test Mode on my 2014 XF Sportbrake 2.2, but didn't need to start the engine via the "Foot on brake" (step 4). So to recap, my method is:

1. Press and hold trip button.

2. Press and hold start button (foot off brake)

3. Count 5secs, release trip button while still holding start.

The engineering test mode comes onto the display and I could then release pressure on the start button and cycle through the test pages using the trip button. Pressing the start/stop button afterwards closes everything down.

Can't say I understood everything I saw, but noted my fault codes as ACC (thanks Jon for explaining this) ICM, HDM and PSM. I'll see if I can find out what these are...…
