Global Positioning System Module: Description and Operation
The control module has a built-in diagnostic system, Volvo Diagnostic, which continuously monitors internal functions as well as input and output
Diagnostic trouble codes (DTCs)
A diagnostic trouble code (DTC) is stored if the control module detects a fault.
Reading and erasing diagnostic trouble codes (DTCs)
Stored diagnostic trouble codes (DTCs) can be read off and erased using this function.
Note! Certain functions are unavailable until the diagnostic trouble codes (DTCs) have been erased.
Reading off input and output signals
This function can be used to continuously read off the values and status of the control module's input and output signals.
GPS Received position, longitude. Indicates the received longitudinal position.
GPS Received position, latitude. Indicates the received latitudinal position.
GPS satellites accessible. Indicates the status of how many satellites the global positioning system module (GPS) is in contact with.
The following status responses may be obtained when reading the available GPS satellites:
Not available - no contact with satellites
No fix - contact with satellites but unable to fix a position
2D Fix- contact with a satellite, two-dimensional position fixing
3D Fix- contact with a satellite, three-dimensional position fixing.
Reading off the control module identification
VIDA identifies control modules by reading off a number of codes from the control module memory.
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
