Diagnostic Functions

Diagnostic functions

General
The control modules have a built-in diagnostic system, Volvo Diagnostic, which continuously monitors internal functions as well as input and output signals.

Diagnostic trouble codes (DTCs)
If the control modules detect a fault, a diagnostic trouble code (DTC) is stored. A fault that was detected during the last operating cycle is defined as permanent. Other faults that are detected are defined as intermittent.

Reading and erasing diagnostic trouble codes (DTCs)
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.

Activating components and functions
Use this option to activate components / functions in the power seat module, left (PSL) and power seat module, right (PSR).
For more information on activations, see Vehicle communication information under Specifications, other.

Reading off and programming data
With this option it is possible to read programmed data and to program in data.

Note! If the control module has been replaced, the position of the seat must be initiated using a diagnostic function.

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)
- software P/N
- diagnostic software P/N.
