11.3 Diagnostic Hardware
The TEBS E only enables diagnosis via one of the CAN interfaces, see following
options.
The CAN interface conforming to ISO 11898 can be used connecting SUBSYS-
TEMS e.g. IVTM, Telematics, SmartBoard or ELEX.
For further information please refer to the document ‘Diagnosis – Soft-
ware/Hardware’, see chapter 4 ‘Introduction’, page 12 => Se
ction ‘Further informa-
tion’.

Diagnosis
A system diagnosis must be carried out every time anything unusual is noticed in
the system or a warning lamp / fault indicator lights up.
Currently faults as well as intermittent ones are stored in the TEBS E diagnostic
memory and displayed via the TEBS E Diagnostic Software. The Diagnostic Soft-
ware provides instructions for a repair.
Once a fault has been eliminated, the diagnostic memory should always be cleared.
