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.
If a fault disappears for any reason after the diagnostic trouble code (DTC) has been permanently stored in the control module, information about the
fault remains in the control module.
Reading and erasing diagnostic trouble codes (DTCs)
Stored diagnostic trouble codes (DTCs) can be read off and erased using this function.
Diagnostic trouble codes can only be erased once all the diagnostic trouble codes have been read out at least once.
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.
The following parameters can be read off:
GPS Received position, longitude. Indicates the received longitudinal position.
GPS Received position, latitude. Indicates the received latitudinal position.
The following 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 satellites, two-dimensional position fixing.
3D Fix- contact with satellites, three-dimensional position fixing.
Reading off the control module identification
The diagnostic tool 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
