UPDATE FIXED JAN 2025

Problem has been solved. I chased the issue for some time by myself, but it was really beyond my skillset. For someone that knows what they are doing-it took my mechanic who has worked on Mercedes for 14 years about 20 minutes. He used a multimeter and targeted the Brake Booster Sensor/Brake Booster Diaphram Position Sensor Part Number: 6500-08044460-info from Partsgeek.com (Chrysler Crossfire Service Manual calls the part "BAS Diaphram Travel Sensor"). He showed me that there was a possible voltage drop that seemed miniscule to me. I don't remember the #, but maybe it should have read 5 and it was 4.9. To me, that was close enough, but not in spec for him.

So the brake booster sensor came in to be replaced. (simple fix using a longer pick set) When he removed the brake booster sensor, it came out a littlle wet. Not knowing what I don't know, I would have just replaced it. He informed me that it should be DRY. So that meant that the master cylinder had leaked into the brake booster. So the brake master cylinder, brake booster and sensor had to be replaced. It has been fixed since January of 2025. The person who I purchased the car from, had a used/original brake booster from a parts car and mailed it to me saving me a hundreds of dollars. (Mercedes may sell a new brake booster for $800?)..




Vehicle: 2006 Chrysler Crossfire Limited Roadster, 29,900 miles. Vehicle was purchased out of South Carolina about August 2024. (I live in NC)
Last week, only the BAS/ESP was on and of this week the ABS appeared. .

Scan Tool 1: iCarsoft i980 with Mercedes software: scan Transmission TCM, Fault / 1, code P2314. State: Current and Historic [One or More Messages from Control Unit N73 [EIS] Control Unit. Are Not Available on the CAN BUS] Or [One of More Messages from Control Unit N93 (Central Gateway Control...), sorry I didn't get a pic of the last few words. The scanner is unable to read the ABS module

Scan Tool 2: [b]Topdon ArtiDiag 600S scanned as a Crossfire: it found code 2314 CAN communication electronic ignition switch distorted. And a few other codes: C8001, 3FFF-000-please refer to service manual. These codes are not part of the XF codes.

Scan Tool 3: Innova 6100p scanned as a Chrysler Crossfire: code P2314 Ignition Coil 5 Secondary Circuit-Insufficient Ionization. So I switched coil pack 4 and 5. The same code is still present. I did not change the plug wires or look at the spark plug. I also exchanged the refurbished RCM in 2023 by D.J. with the newer refurbished RCM 2024

I have tried to elimiinate the issue:
- Reset: the Left, Right, Center reset.-it hasn't worked yet with many attempts
- I aired the tires to 35 psi.
-Disconnect the negative battery terminal for 30 minutes. A DieHard battery was purchase around August and voltage is good. The vehicle is garage kept on a battery tender.
-The brake fluid is full, brake lights work, fin/spoiler goes up/down at it should, cruise control works, wheel speed sensors are equal from live data (the front is a little faster than the rear-size of tires).
- Previous owner performed a transmission tune, new Akebono brakes (squeak),new brake lines, rotors, belt, idler pulley, valve cover gaskets, rear differential fluid.
- Previous owner installed front rotors/calipers and pads that can be used on the SRT. (rear: everything is the base model)

The cars rides smooth, but I have not driven it more than about 15 minutes at time and only short distances in town because I don't want to get stranded.


From about August to today:
-I have upgraded to a 74mm Throttle boday and bigger MAF and used the old MAF sensor.
-Added a new car stereo head unit
-Fixed the "sticky key"
-Re-torqued the passenger side valve cover bolts to 7 ft, lbs (have not done the driver side yet_
-Changed oil filter and oil

I'm still reading the forums to try and find an answer. If you suggest a multimeter: I only know how to check battery voltage, and would need guidance to put a probe here and a probe there. Thanks again for any assistance.
