SERVICE:
NOTE: This TJ applies only if the customer does not experience any problems charging the vehicle.
The DIM message “Disconnect Charging Cable” while no charging cable is attached, can result from a
software issue.
The technical background is that the OBC is not getting woken up at the moment the customer wants
to start the car. Without having clear feedback from the OBC that no charging cable is attached, for
safety reasons the DIM message “Disconnect Charging Cable” is shown.
If a customer reports this symptom, please give advice that there are three workaround options every option working on its own:
A. Press the release button at the EVI.
B. Press the release button in the charging menu in IHU.
C. Lock the car and wait for 10 minutes (so it’s going to sleep), then unlock.
Note: In some cases, the DIM message may disappear within a short time on its own.
Whenever this symptom occurs while the car is at the workshop, there are two additional workaround
options - every option working on its own:
D. Do a 12V reset.
E. Remove fuse 27 in EJB for approx. 2 min.
Do not replace any parts, a software fix is under development.
List of abbreviations:
DIM - Driver Information Module
OBC - On-board Charger
EVI - Electric Vehicle Inlet
IHU - Information Head Unit
EJB - Engine Junction Box
PCA - Permanent Corrective Action
