Diagnostic Help

Fault diagnosis concerns electrical faults in connecting lead to ABS (ABS or TC/ABS are checked for faults first). If the car is equipped with TC/ABS, communication with ECM will take place through the P-bus. For further information on fault diagnosis of bus communication with TC/ABS, see Fault diagnosis strategy for electronic systems. If TC/ABS is absent from the bus, DTC P1925 will be generated.

Functions in the diagnostic tool related to the fault are:

• Diagnostic status for the diagnosis.
• Vehicle speed (Leads from ABS, alternatively bus from TC/ABS.), unit KM/H.
