NOTE: The Motor Control Module (MCM) monitors rail pressure during engine shut down and compares it to a stored learned value. If the bleed-down rate has changed due to leakage and it is below the learned value, this code will set.

DESCRIPTION:Leakage in high pressure fuel system to high (leak down test).

MONITORED PARAMETER:Fuel rail pressure.

TYPICAL ENABLING CONDITIONS:Key off

MONITOR SEQUENCE:None

EXECUTION FREQUENCY:Once when enabling conditions met.

TYPICAL DURATION:30 seconds

DASH LAMPS:1. MIL2. CEL

VERIFICATION:Rail pressure bleed off test using the diagnostic service tool.
