There are four types of codes that EFILive can report via the handheld (standalone operation):
- EPA Current
- EPA Pending
- MFG Set
- MFG All
EPA Current: Will show all emissions related coded that are currently set as active codes in the controller.
EPA Pending: Will show all emissions related coded that have had one or more tests fail but not enough tests to trip the "Current" threshold and set the actual code. Pending codes help you diagnose a fault before ALL conditions met.
MFG Set: Will show all codes that have any of the following flags associated with them:
- Warning lamp is illuminated
- Stored code
- Current code
MFG All: Will show all codes that have any of the following flags associated with them:
- Warning lamp is illuminated
- Warning lamp is pending
- Stored code
- Current code
The Codes are displayed with their status on FlashScan's screen. You should understand what each letter of the code means. Some scanners will only report specific combinations of these letters.
The letters and their meanings are explained below:
For GM: MFPHXNCIM = The code has requested the MIL to be illuminated
F = Test failed this ignition cycle
P = Test passed this ignition cycle
H = Freeze frame data was captured for this code
X = MFG specific
N = MFG specific
C = Code is currently set
I = MFG specific
So "MFG Set" will show all codes that are causing the MIL to illuminate (M) or are current (C) or stored (H).
And "MFG All" will show all codes that are causing the MIL to illuminate (M) or are current (C) or stored (H) or pending codes (F).
For Cummins: MWOH12CI
M = The code has requested the MIL to be illuminated
W = MIL is pending, Code is immature and will illuminate the MIL if/when the code gets set
O = Old code, was set but is no longer set
H = Freeze frame data was captured for this code
1 = MFG specific
2 = MFG specific
C = Code is currently set
I = Immature code, not enough data collected to set code yet.
So "MFG Set" will show all codes that are causing the MIL to illuminate (M) or are current (C) or stored (H).
And "MFG All" will show all codes that are causing the MIL to illuminate (M) or are current (C) or stored (H) or pending codes (W).
Using V7 in pass-thru mode you can select exactly which of the 8 flags you want to scan for using the following screen:
