Diagnostic Functions

Diagnostic functions

General
The control module has integrated diagnostics that continually monitor the module and the input and output signals.
If the control module detects a fault that prevents communication on the CAN network, it will only be possible to move the seat using the buttons on the control panel. The remote key memory will not be operable.
If a Hall sensor is defective, it will only be possible to move the seat manually. All memory functions are disabled.

Diagnostic trouble codes (DTCs)
If the control module 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.

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