96 F-150 Airbag code 45
If you don't know what you are doing with this airbag system, I suggest you take it in to a professional to get it fixed. If you screw up and accidentally deploy the airbag it'll really cost you to get it replaced!! Not to mention if you get hurt doing it.
According to my 1995 shop manual it means the lefthand front airbag sensor is improperly mounted.
Here's what my manual says:
The air bag diagnostic monitor measures the resistance between Pin 21 (Circuit 620, P/LB) and Pin 3 (diagnostic monitor reference ground). If the air bag diagnostic monitor measures a difference of more than 2.0 ohms between Pin 21 and Pin 3, it will flash out Code 45.
Note that Circuit 620 (P/LB) is attached to the side casing of the LH front air bag sensor and bracket. In addition, the case is grounded to the vehicle.
Possible Causes
High resistance on Pin 21 (Circuit 620, P/LB) to ground can be caused by:
(1) A poor connection due to loose mounting, dirt, or corrosion at the mounting location of the LH front air bag sensor and bracket.
(2) An open or damaged wire in Circuit 620 (P/LB) from Pin 21 of the diagnostic monitor harness connector to radiator support LH front air bag sensor and bracket. This includes splices and in-line connectors.
(3) NOTE: Circuit 620 (P/LB) passes through an in-line connector between the main instrument panel harness and the engine compartment harness that connects to the LH front air bag sensor and bracket.
An open wire or loose (Circuit 620 P/LB) wire attachment inside radiator support LH front air bag sensor and bracket.
Check splice and in-line connectors for poor crimps, etc.
