Mercedes module listI use an icarsoft scanner. When used in the "Quick Test" mode, it appears to look for all possible modules, and then if found, they are in the list. Running the scan again will not show these modules again.Here's the initial list, and the highlighted ones "disappear" after the scan. TCM - Transmission Control ModuleESM - Electronic Selector Module -DIS - DIStronic - radar DIStance systemECM - Engine Control Module - i have P1999 refrigerant pressure too highSBC - Supplemental Braking Control - a system that pre-applies brakes for youESP - Electronic Stability Control -ABC - Active Body Control -TPMS - Tire Pressure Monitoring System - ?? weird, thought I had it, perhaps disabledSRS - Supplemental Restraint System - airbag controlBMS - Battery Management System - module that protects from overvoltage and reversed connectionsOCP - Overhead Control Panel -EIS - Electronic Ignition Switch -HRA.FR - Headlight Range Adjustment - Front RightHRA.FR - Headlight Range Adjustment - Front LeftLCP - Lower Control Panel - mirror, roof, roll barPSE - Pneumatic System Equipment - pressure and vacuum pump in trunkSAM.DR - Signal Actuation Module DRiver -SAM.PASS - Signal Actuation Module PASSenger -Rear SAM - Signal Actuation Module in REAR - trunk lidRVC - RolloVer bar Control module - Circuit 15, 15R, and roofKG - Keyless Go - wireless key card to unlock and start carIC - Instrument Cluster - ambient temp sensorSCM - Steering Column ModulePTS - ParkTronic SystemD2B - fiber optic ring for connecting modulesCDC - CD Changer -CTel1 - Cellular TELephone 1 -CTel2 - Cellular TELephone 2 -VCS - Voice Control SystemSOUND - SOUND systemTele Aid -TV - TeleVisionDCM.L - Door Control Module LeftDCM.R - Door Control Module RightESA.FL - Electronic Seat Adjustment Front LeftESA.FR - Electronic Seat Adjustment Front RightOSB.FL - Orthopedic Seat Backrest Front LeftOSB.FR - Orthopedic Seat Backrest Front RightAC - Air Conditioning - B1257.000/.001 refrigerant pressure too low - can clear - Multifunction sensor hereSTH - STationary Heater with Remote Control
Fault finding and fixing ICarsoft tipsenter the vinI've not been able to store the vin, nor read it from the carbe sure to look at date of manufacture to get the right version software2 types of scans, smart scan (looks for all modules) and manual (you pick the module) List of module abbreviations:
Mercedes HVACOK, the car sat for 4 years.Try to turn on the AC gives a blinking red light in the button, and eventually just red.thought it was a bit low, but the shop (while rebuilding the ABC system) put a bit of freon in it, but no go. Bought a carsoft II unit and started working the problems. After clearing all the faults caused by low voltage, still having issues. B31 multifunction sensor read temp and dewpointalso OCP console under air temp, read 350 N70m1 (inner blower motor temp sensor), and 340 n70b1 (innet air temp sensor) Pressures: Pressures should be checked at 2000rpm. Low side about 40, high 250. (need better references) Ambient temperature can change those numbers though so keep that in mind. Sensor B12/2 is in receiver drier. Need to recover refrigerant to replace it. Electrically it is connected to left front SAM. Here's some links I am persuing: Even after you have the correct amount of refrigerant installed, the compressor won't run until you reset the system. 1) Set the car in park and turn on the engine, hold the rest and particle filter buttons down together for about 5 seconds (The screen will show searching) 2) This screen gives you the fault codes. If you're curious, scroll up and down to see them using the temp up and down switch. 3) Pop out the left "auto" button and right "auto" button. 4) Now press the the left button in, and then the right one. The system will reset. 5) Turn the car off, wait a minute, then turn it back on again. If you don't have any further problems, the light should stay off. (If it comes back on again, you have more things to do). I suggest that you write down or print out the reset procedure and put it in the glovebox. That will let you reset the system if the refrigerant gets a little low on a trip - your passenger will appreciate it.

To start, the key must be removed from the ignition. Insert the key and turn to position 1. Immediately press and hold the trip odometer reset button until the instrument cluster beeps. There is no visual message, only an audio beep. Be patient, this takes around 40 seconds. Press the lower menu button (it looks like two sheets of paper, the one with the writing in the background behind the blank one) Press the up arrow button. Press the "+" sign to disable the Traction System (turn "ON" test mode) Start the engine, the traction system is now disabled. To return to normal, remove the key and restart the engine. The traction control warning should no longer be in the cluster. If it is, shut the engine off and remove the key again. Then insert the key and turn to position 1. Note that the DYNO test screen is displayed immediately. Push the "-" button to enable the traction system (turn "OFF" test mode)Note : When you first turn the key to position 1, ESP DYNO Test screen pops up, then after 1-2 seconds it may disappear while faults are displayed. If you weren't fast enough in pressing the "-" button before codes were displayed, just wait until all codes cycle by, then the ESP DYNO Test screen will reappear Here's how. To start, turn the ignition key to the first accessory position, making sure the dash display shows the odometer. The SRS airbag light should be on. Press the trip odometer reset button three times rapidly before it goes off. If you do this right, a screen will appear showing a voltmeter. Then press the "up" arrow on the left side of the wheel twice to take you to the "ESP dynamometer test" screen. Using the plus (+) button on the right side of the wheel, select "on." And then start the car. Warnings will appear informing you that the ESP, ABS, and BAS (brake assist) aids are now turned off and you're on your own.If you did it right, you've put the car in a mode intended for diagnostic testing on a rolling dynamometer—all electronic supervision is unplugged. Unhindered by techno-aids, the SLK's grip on the skidpad improved by 0.03 g compared with simply hitting the ESP switch on the dash. To return all the safety technology, scroll back to the dyno test screen and select "w/t. 15 off" with the minus (-) button. Shutting off all the electronic aids isn't easy, and that should tell you something. Owners are not generally privy to the dynamometer mode; therefore, we will continue to publish test numbers attained with the dashboard ESP switch turned off. We just thought you'd want to know.
