Checking The Programmed Values
- Ignition on.
The control module has registered an incorrect number of parameters in the vehicle configuration file.
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the central electronic module (CEM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs.
The control module must be reprogrammed to remedy the fault.
The customer parameters must be read off, if not already been done, before the software is downloaded.
Read off and note the values.
These parameters must be re-entered using VIDA (Volvo scan tool) after programming.
