Diagnostic Functions

Diagnostic functions

General
The Parking Assistance Camera (PAC) does not have a built-in diagnostic system. In the event of a fault in any of the components that are required to generated or transmit image information from the camera to the display screen, a black screen is shown instead. It is only shown if the fault occurs when the Parking Assistance Camera (PAC) is activated, and is only shown once.

Activating components
This function can be used to activate components to check that they are working.
For more information on activations, see Vehicle communication information under Specifications, other.

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 the following 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 (part of the software).
