CONCERNS

Control units for rear-end and front-end electronics 

INFORMATION

If the rear-end electronics control unit (rear BCM) needs to be replaced, the front-end electronics control unit (front BCM) must be flashed accordingly to the new software version 2900. 

If a problem  causes an error message to be displayed in the instrument cluster or an entry in the fault memory, for example:

and if the existing rear-end electronics control unit is replaced by a new rear-end electronics control unit  with the part number 7PP.907.279.BF  , the software version of the front-end electronics control unit  must be read out using the PIWIS Tester and programmed to the new software version 2900  if necessary (existing software version is less than 2900).

The required programming routine is available in PIWIS Tester software version 13.800 or higher.

WORK PROCEDURE

  1. Re-program front-end electronics control unit  (also rear-end electronics control unit automatically by entering the programming code) using the PIWIS Tester with software version 13.800  installed:
    1. 1.1 Carry out general preliminary work for control unit programming as described in → 9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester - section on "Preliminary work" 
    2. 1.2 The basic procedure for control unit programming is described in the Workshop Manual: → 9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester  .
      WORK PROCEDURE

      Required PIWIS Tester software version: 13.800  (or higher)
      Type of control unit programming: Control unit programming using the 'Campaign' function in the Additional menu  on the PIWIS Tester by entering a programming code.
      Programming code: G2E3T 
      Programming sequence: Read and follow the information and instructions on the PIWIS Tester  during the guided programming sequence. During the programming sequence, the Lane Change Assist (LCA) control unit is re-programmed  and then re-coded automatically. 
        Do not interrupt programming and coding. 
      Procedure in the event of error messages appearing during the programming sequence: → 9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester - section on "Troubleshooting". 
      Procedure in the event of abnormal termination of control unit programming: Repeat control unit programming by restarting programming.
    3. 1.3 Carry out general subsequent work for control unit programming as described in → 9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester - section on "Subsequent work". 
  2. Teach all remote controls (keys): 

    Information 

    All remote controls (keys) are required for teaching a DME, front-end electronics (front BCM), rear-end electronics (rear BCM), electronic steering lock (ELV) control unit or remote controls (keys) for example.

    Remote controls (keys) that are not taught during this teaching procedure will no longer be recognized by the vehicle.

    NOTE: Voltage drop
    • Risk of irreparable damage to control unit
    • Risk of damage to control unit
    • Fault entries in the control unit
    • Coding in the control unit is aborted
    • Malfunctions in control unit, even during programming

    → Switch off the ignition and remove the ignition key before disconnecting the control unit.

    → Ensure that the power supply is not interrupted during programming.

    → Connect a battery charger with a current rating of at least → Nominal value: 40 A  to the vehicle battery.
