Internal Fault
Internal fault
Checking for permanent or intermittent faults
Check that the remote control is working.
Does the remote control function?
Yes - Intermittent fault
No - Query
-------------------------------------------------
Query
Has the central electronic module (CEM) been replaced recently?
Yes - Ordering software
No - Replacing control module and programming
-------------------------------------------------
Ordering software
- Ignition off.
If the central electronic module (CEM) was replaced before DTC001F was stored, the fault is probably in the data sent from the central electronic module (CEM). In this case the central electronic module (CEM) must be reprogrammed.
To download software to the relevant control module, see Replacement parts catalogue/Software index.

Replacing control module and programming
Note! If possible, read off the programmed data from the control module before it is replaced.
- Ignition off.
The upper electronic module (UEM) has registered an internal fault.

Replacing the control module
Reading off the programmed values
Note! Read off the programmed values from the upper electronic module (UEM) before replacing the control module.
- Ignition on
- Click on the symbol for VCT2000 to read off the programmed values.
The retained values are programmed customer parameters in the upper electronic module (UEM). The retained values should be noted for later use.
Other information
- For information about programming the customer parameters, see Diagnostic functions Diagnostic Functions.
Continue - Replacing control modules and downloading software
------------------------
Replacing control modules and downloading software
Caution! A new control module is delivered without software. In order for the control module to function new software must be programmed into the control module after it has been replaced.
Replace the control module and download the new software. See Upper electronic module (UEM) rear view / door mirror, replacing Service and Repair.
Hint: When diagnostic trouble code (DTC) E001 is stored, communication with the control module cannot be established. This can be remedied in two ways.
1. Press the remote control button for local lighting
2. Remove fuse 11C/28 from the fusebox in the passenger compartment. Reinstall the fuse again.

Checking the interior lighting
Two times can be programmed for the interior lighting:
1. Short
- The period from when the door is unlocked, or the engine stops, to when the interior lighting goes out can be changed if it is too long or too short.
2. Long
- The period from when the door is opened, or a lamp is lit with a switch, to when the lamp goes out can be changed if it is too long or too short.
To program a long interior lighting period you must step ("click") through the short interior lighting period programming.
Continue - Programming a short interior lighting period
------------------------
Programming a short interior lighting period
The general lighting and rear reading lamps light and remain lit for 30 seconds when:
- The door has been unlocked from outside with a key or the remote control.
- The engine has been stopped and the ignition key turned to 0.
The default period is 30 seconds. This can be changed to between 5 and 255 seconds.
Read off the programmed values.
To change the time, mark the desired value in the scrolling list and start programming.
Do you want to program any more parameters?
Yes - Programming a long interior lighting period
No - Fault Found
------------------------
Programming a long interior lighting period
The general lighting and rear reading lamps light and remain lit for 10 minutes when:
- A door is opened after being unlocked.
- The lamp is lit with a switch.
The default period is 10 minutes. This can be changed to between 0 and 255 minutes at 10 minute intervals.
Read off the programmed values.
To change the time, mark the desired value in the scrolling list and start programming.

Checking the anti-dazzle function in the rear view mirror
Checking the anti-dazzle function
Note! If the upper electronic module (UEM) has been replaced software, specially developed for downloading after replacing the control module, must be downloaded to the control module before the anti-dazzle function is changed. See Upper electronic module (UEM) rear view / door mirror, replacing Service and Repair.
The rear view mirror anti-dazzle function can be adjusted:
- If the rear view mirror anti-dazzle function is too powerful or too weak, it can be adjusted.
Specific software for setting the anti-dazzle function must be installed in the car to do this.
Order the software. See9499432.
Install the software. See9499432.
