What is SAM module and how do you change it?
CAN B is the interior (or body) data bus; CAN C is the engine/chassis data bus; and CAN D is the diagnostics data bus. One can see that a problem may occur at the :surrender::bowdown: control; at the component being operated; somewhere in the CAN bus; or in the SAM itself (including fuses and relays).
Where is the SAM module located in a Mercedes Benz?
The location of the SAM module depends on the Mercedes-Benz chassis. Most SAM modules are usually installed by the fuse box. Mercedes-Benz cars may have a rear and front SAM module. Left SAM in located in engine compartment.
Where does the left Sam sensor come from?
The left SAM gets signal input from the left front brake pad contact sensor, refrigerant pressure sensor, refrigerant temperature sensor, outside temperature display temperature sensor, brake fluid indicator switch and parking brake indicator switch.
What causes the SAM Control Module to corrode?
(Source: W220.ee) Corrosion – It is possible that the SAM control module may have gotten wet, corroded and eventually failed. Typically this is caused because repair is performed in near the SAM control unit. If the SAM modules are not closed and sealed, properly they will eventually corrode.
Where is the hid module on a Xenon headlight?
On models with high intensity discharge (HID) or Xenon lights, the HID module is located at the bottom of the headlight. Water can enter the module electrical connector causing headlight faults. If this happens to you, you will have to replace the headlight, the electrical harness and the HID module.
