Time after start > 30 sec.
Regardless of whether EVAP is active/inactive
Terminal condition: Terminal 15, engine on
Voltage condition:
Voltage in onboard electrical system >= 10 V
Condition for fault memory entry
0.2 sec.
Action in service
1) Visual inspection of HFM plug contacts
2) Check wiring between HFM and DME
3) Check induction system/crankcase for leaks (the positive
crankcase ventilation system can allow vacuum leaks with
air from the crankcase entering the manifold, for instance, if
vacuum line from brake booster to vacuum pump is leaking)
4) Check for DISA diagnostic fault code entries and DISA
control operation (DISA fault does not prevent HFM
plausibility check)
5) Carry out VVT travel limit initialization routine
