Troubleshooting & Technical Questions & ModificationsHave technical or modification questions about the Crossfire?
Find out the answer, or give advice in here!
this thread started with BAS/ESP question. The codes show above relating to that problem are 1860 1875 and 1160.
1160 relates to the ESP/Yew rate sensor in the center console. That sensor is wired directly to the CAB Control Anti-lock Brake. Check all connections and wiring for continuity. Basic resolution to the code is clear all codes, start car for a couple minutes; turn it off and check again for codes, if no codes then drive car and see if code returns. Code still there replace yew sensor.
1860 is Shift Lever Assembly SLA, CanBus problem between SLA and CAB
1875 is SLA Can C Bus between Transmission Control Module
That 1040 PCM CanBus code should be corrected before assuming a SLA problem. The 1040 code refers to the SLA CanBus connection to the PCM at connector C4 #1 and #11 ( those wires run through a connector at the TCM and a splice in the engine bay)
All codes point towards the SLA, but check that canbus at the PCM first.
With all the problems you are having with your car I suggest going to ebay and purchase a Crossfire Service Manual. It comes in three volumes and you need all three. It would be money well spent!
Thanks a lot for the reply and information! I’m familiar with the yaw sensor and its location should I start there? Also is this service manual you’re talking about the same one available on the forum? If so I already have it just was trying to get some guidance on where to begin. It’s hard to believe the cars having this many issues.

Just so I know I'm starting at the correct place, I'm going with the 1040 code and starting at page 8E-45 of the service manual? "NO RESPONSE FROM SHIFT LEVER ASSEMBLY" I've found the PCM, but I cant figure out what connection is C4 having a hard time with the manual.

So if I am on the correct page I'm running to an issue already. I've turned the key to the on position with the SLA harness removed I tested the wire where the black arrow is pointing (2nd row 1st hole) and put the black probe to a nearby ground. I'm not getting a voltage reading at all. I did step 4 just for the heck of it and I am getting a reading across that terminal. So would I be hunting for a break in the wire? "Repair the traction system relay output for an open" ?

Okay I just found the C4 connector on the PCM, I tested #1 and #11 those test at 1.05V is this normal? I just put the black probe to the battery ground.
Any suggestions starting to stress because I start a new job next week
Look you are one of the first ones to show codes from a Snapon scanner. It is hard to know if it is truly compatible with a Crossfire. Your friend should clear all codes from your car completely then wait and see what happens after.
If your concern is the BAS/ESP light then it could be the steering angle sensor or the Yaw sensor. It is unlikely that both would be defective at the same time.
You probably need to get an aftermarket Mercedes scanner or someone close by to scan it with a DRB 3 emulator. If you post your location maybe someone will help you.

Thanks for the reply, yes the codes where wiped after the first set of pictures I’m not concerned with anything other then BAS/ESP system atp. The second set of pictures is the current codes it’s throwing. Im not concerned about the YAW sensor I can pull one from the local junkyard for $40, im more so asking how to trouble shoot the SLA someone suggested above but I can’t find it in the service manual. I don’t want to throw 300$ at a used SLA if that’s not the issue.

Is your car not shifting or does the dash only have a black square or is in limp mode? The SLA is as low as 149 on eBay and even lower if you found one at a salvage yard. The Yaw sensor is different for a 2005-2008 Crossfire. The 2004 is exactly as a 2004 Mercedes SLK 320.

Shifting normal just did a transmission service and flush at 55k, no limp mode. Luckily the crossfire in the local junk yard is the same year but I think its the base because of mesh seats. Hopefully that YAW sensor will be fine at this point I guess I'll just do some more research and try to confirm its the SLA.
Problem solved! Turns out it was just the YAW sensor went to a local junkyard pulled the part, drove the car for 5 mins and the light went out! Looks like you guys where right as far as the snap on scan looks like you have to use DRB3 emulator to truly read the car.
