I have a 2002 ford expedition xlt and the airbag code is 74. what does that mean?


Well I can't find flash code 74 for a 2002 expedition. But looking up the code from Ford it says:
Intermittent Or Rewired Driver's Airbag Module Circuit Low Resistance Or Shorted

Maybe double check the flash code to make sure.

What do these codes mean E31-E41-E74-F31? can you help?


E31 = Shorted MAP cicuit sensor
E41 = Cam sensor circuit problem
E74 = Intermittent MAT

F31 = Display panels to BCM problem

This is to say if the vehicle is a 1991 Cadillac Deville
Then the Trouble Codes are as I listed above.
For future reference, the F is for BCM codes.

When entering the on screen diagnostics the display starts with one E for the PCM history, then E.E. for current. Same sequence follows for BCM codes starting with one F for history and F.F. for current ones

Here is a heated seat TSB for cars built prior to 12/14/07

TSB 09-4-8
03/09/09
INOPERATIVE HEATED SEAT(S) - BUILT
BEFORE 12/14/2007

FORD:
2005-2007 Five Hundred, Freestyle
2008 Taurus X, Taurus

MERCURY:
2005-2007 Montego

ISSUE
Some 2005-2007 Freestyle, Five Hundred, Montego and 2008 Taurus, Sable and Taurus X vehicles built before 12/14/2007 may exhibit an inoperative heated seat(s). This concern may be caused by an intermittent open element in the heated seat mat.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
The heated seat system is controlled by the heated seat module located underneath the front passenger seat cushion. The heated seat switches are part of the heating ventilation air conditioning (HVAC) module but the heated seat system operates independently from the climate control system. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat located in the cushion heater mat. The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off. For vehicles built before 5/1/2006, the module will time-out and switch off after 10 minutes.

1. Refer to Workshop Manual (WSM), Section 501-10 for pin point test on inoperative heated seat(s).
a. When testing the heater mats resistance and circuits for an intermittent open, technicians should sit in the seat while testing the circuit resistance, move the seat in multiple seating positions and apply pressure to several areas of the heated seat mat to ensure the mat element is not open intermittently.

2. Refer to WSM 501-10 for heated seat element replacement when an open electrical circuit has been identified.

Parts Block
WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage

I hope this helps to solve it.
