Fault diagnosis concerns electrical faults in connecting cables to ESP. Communication with Trionic is on the P-bus. For further information on bus communication with ESP, see FAULT DIAGNOSIS STRATEGY FOR ELECTRONIC SYSTEMS . If ESP is missing from the bus, DTC P1625 will be generated, see P1625 .

• Diagnostic status for the diagnosis.
• Vehicle speed (Lead from ABS, alternatively bus from TC/ABS), unit km/h.
