Diagnostic help
WARNING: This page is about a different car, the 2003 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
Fault diagnosis starts with leak detection. After fault diagnosis and diagnostic procedure, a final check is made when the cold start diagnosis is initiated. The diagnostic tool indicates whether or not there is a leak in the system.
Diagnostic tool functions related to this fault are:
- Tank pressure, unit kPa.
- Activating EVAP diagnosis.
The cold start diagnosis can be initiated with the diagnostic tool irrespective of what the coolant temperature was when the engine was started. At high temperatures and when the EVAP canister is saturated, it may be difficult to carry out the diagnosis as the additional fuel from the purge is then often more than 7 % of the engine's fuel requirements.
