Stored diagnostic trouble codes (DTCs) can be read off and erased using this function.
Diagnostic trouble codes (DTCs) can only be erased once all the diagnostic trouble codes (DTCs) have been read off at least once.
Note! Certain functions are unavailable until the diagnostic trouble codes (DTCs) have been erased.
Reading off the control module identification
VIDA identifies control modules by reading off a number of codes from the control module memory.
The codes contain information about the control module:
hardware P/N (control module without software)
hardware serial number (control module without software)
diagnostic software P/N.
Reading off extended fault-tracing information
This function can be used to read parameters, status identifiers and counters stored at the same time as a diagnostic trouble code (DTC). These are called
The multimedia module (MMM) is an option and has the primary task of the managing the functions for:
Traffic message channel (TMC)
FM multiplex (Japan only)
Only the display screen is directly connected to the multimedia module (MMM). The DVD player is integrated in the multimedia module (MMM). The
functions from other control modules are via the MOST network, but are managed using the multimedia module (MMM). The system is not compatible
with music or film CD or DVDs.
The multimedia Module (MMM) uses the MOST network to communicate with other control modules.
The control module checks activations and input and output signals via an integrated diagnostic system. A diagnostic trouble code (DTC) is stored if the
control module detects a fault. Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using
VIDA via the data link connector (DLC) in the vehicle.
In order to work correctly on the MOST network, the infotainment control module (ICM) checks that the serial number in the multimedia module
(MMM) is correct. The multimedia module (MMM) will not function if the serial number is incorrect. Try switching the ignition off and on if there are
problems when replacing the multimedia module (MMM).
A simple way to ensure that the multimedia module (MMM) is powered is to insert and then remove a DVD. If this does not work, check that the control
module is powered and grounded.
The multimedia module (MMM) is located in the glove compartment.

The table below summarizes the input signals to and output signals from the multimedia module (MMM). The signal types are divided into directly
connected signals and MOST communication. The illustration below displays the same information with the Volvo component designations.
