Mercedes to Chrysler part name mapping
| Mercedes Name | Mercedes Internal Name | Chrysler Name | Description |
|---|---|---|---|
| Content cell | K40 | RCM
Relay Control Module |
A module that controls circuits through relays, such as Traction Control, Engine Control, exhaust gas monitoring/control (EGR, catalyst sensors), Secondary Air Injection (SAI).
- Multiple trouble codes about O2 sensors - Secondary Air Injection trouble codes - No crank, no start. (Check Engine light also doesn't come on, no power to PCM) - Traction control lights on or stay off (no power to ESP/BAS) - No fuel pump power/pressure (fuel pump relay doesn't work) - Intermittent Secondary Air Injection codes (bad solder) |
| Radio frequency DAS control module | N54/3 | SKREEM
Sentry Key REmote Entry Module |
Key component in the car theft protection. Immobilizes the car, as well as tells the Central Locking Pump to unlock the doors, and the siren to go off if things arent OK
|
| CCM
Multi-function Control Module (basically first-generation SAM, or Signal Acquisition Module) |
N10-3 | BCM
Body Control Module |
|
| PSE control module | A37 | CLP
Central Locking Pump SSM Security System Module |
This is the pump that drives the vacuum of the locks, but also monitors the state of the car and triggers alarm if something is awry.
This module also seems to include a Crash Sensor, to automatically open the doors 8 to 11 seconds after a crash is detected.

| ME-SFI [ME] control module | N3/10 | PCM
Powertrain Control Module |
Also known as (Engine) ECU, ECM. Its the thing that makes your engine run. |
| Lock confirmation relay | K54 | Remote Keyless Entry Relay | Makes the lights blink when the car is (un)locked |
| Transponder Coil | L11 | Transponder Coil | Used by the SKREEM to read the transponder inside the key fob. |
| Data link connector | X11/4 | Data link connector | The OBD2 connector under the dash. |
| Alarm Signal Horn with additional battery | H3/1 | Siren | Battery-backed siren module.
|
| ATA [EDW] inclination sensor | B33 | Anti-theft Tow Sensor | Notices if your car is being tilted |
| Light module | N7-1 | Illumination Control Module | The module handling the Lights knob on the dash |
| Instrument Cluster | A1 | Instrument Cluster | Where all the gauges are at. |
| Cycle module | N65 | Pulse Module | Smaller variant of the K40/RCM, that is located under the driver side engine fuse box, which contains either 1 or 2 (SRT/AMG only) relays. The first relay, k2, controls the Starter (M1), and the second relay, k3, controls the Charge Air Cooler pump, that pumps coolant through the supercharger intercooler.
- If you control pin E.5 manually, you can turn the intercooler pump on or off at will. You might want to put a resistor between the original wire and ground to make the PCM think its controlling it. - Putting power on pin B.2 should emulate putting the key in START. - The single connector with the thick Violet/White wire controls the start motor solenoid.
