Technical Background 1
The replacement part needs to have the diagnostic address/address word changed.

Production Solution
Not applicable.

Service
Process for software version 3112 or 3115 (=UNECE)
The battery charger must be replaced again and the connection sequence for the battery charger must be
observed as described in the workshop manual.
Proceed as follows:
1. Order a new charging unit for the high-voltage battery.
2. Check the charging socket(s) and their resistance before installing and putting the battery
charger into operation.
3. To do so, use the VAS 1594 to measure the following pins on the 60-pin plug on the battery
charger to the electrical system 24 - 60 and 41 - 60. The measure values should be around 2.7k
Ohm or 4.7k Ohm with a tolerance of +/- 5%.
4. Install the battery charger and observe
the connection sequence.
•

First connect the electrical
connectors -1- and -2- (Figure 1).

•

Connect the electrical connector 4- last (Figure 1).

Technical Service Bulletin
5. After installing the battery charger, it must be activated as described in the workshop manual
(Guided Functions: Commissioning 00C6 - Replace control module).
Normally the OBC should log address 00C6. If it logs as 8113 instead of 00C6, proceed as follows:
•

End Guided Fault Finding and if the event memory entries are static, start Guided Fault
Finding again.

•

Work through the event memory entries from gateway 0019 according to the test plan.

If the high-voltage system still cannot be activated, update the electrical system configuration as
follows:
Select the self-test button and then select the following path:
•

0019 - Data bus on board diagnostic interface – J533.

•

0019 - Technical product information.

•

J533 - Technical Product information 2063053.

Process for all other software versions:
If the concern occurs after the component is replaced, proceed as follows using ODIS:
1. If the vehicle has PR number KB4 (onboard charging unit up to 22kW) disconnect
charging unit 2 (AX5) first.
2. Select the self-test button and then select the following path:
•

High-Voltage Battery Charger Control Module 2, J1239 (Diagnostic address 8113).

•

8113 - High-Voltage Battery Charger Control Module 2, functions.

•

8113 - Change diagnostic address from 8113 to 00C6.

3. Run the test plan and the scan tool will correct the diagnostic address.
•

Check that the high-voltage battery charger control module, J1050 is now reporting
in the scan tool under address word 00C6 and the high-voltage battery charger
control module 2, J1239 is no longer reporting under address word 8113.

•

Work through the DTC entries from the gateway (0019) according to the test plan.

If the high-voltage system still cannot be activated, update the electrical system configuration as
follows:
Press “Select self-test” and then select the following path:
