QuestionRagu,
I inspected the front impact severity sensor and mounting bracket and did not find any problems. It says go to V43. Thanks again for you help!

Thanks for great info. I think I need to go to pinpoint test V42 or V54 but I don't see them listed. Where did you find this info and where can I get it? I have the 2002 Explorer/Mountaineer Workshop Manual Published May 2001 but it does not have this information listed. Look forward to hearing back from you!

2002 Ford Explorer 4x4 Eddie Baurer V8
The air bag light is flashing with LFC 42. I have the Ford Explorer Service manual and can NOT find the codes listed. I found on the internet that it refers to front crash sensor (located on radiator support). I checked sensor connection and it appears ok. So I went back to the Ford Explorer Service manual I have and it does NOT show any circuit diagram for this sensor.
Do you know the circuit layout for this sensor and/or familar with LFC 42? Are there any mistakes in the '02 Explorer Service Manual that you are aware of?
THANKS IN ADVANCE!
Answer -
do these pinpoint test just to let you know the air bag sys is nothing to fool around with you can get hurt if you don't know what you are doing. being that said - PINPOINT TEST V: LFC 42, 43, 44, 45 AND 46/DTC B2296 — RESTRAINT SYSTEM IMPACT SENSOR STATUS — VEHICLES BUILT 03/2002 ONWARD
CONDITIONS DETAILS/RESULTS/ACTIONS
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the Pinpoint Test.
V1 CHECK FOR A HARD OR INTERMITTENT DTC
WARNING: Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow these instructions may result in the inadvertent deployment of the safety canopy and risk of personal injury.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
WARNING: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
WARNING: Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
Retrieve/Flag/Record Continuous DTCs
On-Demand Self Test
Flag DTC B2296/Record All Flagged Faults
Was DTC B2296 retrieved during the on-demand self test?
Yes
This is a hard fault. The fault condition is still present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self test.
If a flagged fault of "?" was recorded, multiple faults exist and the entire pinpoint test must be carried out.
For first row driver side impact (F_D_SEN) sensor with a mounting/communications (COMM) fault, GO to V2.
For first row driver side impact sensor (F_D_ SEN) with an internal (INT) fault, INSTALL a new first row driver side impact sensor. REFER to Side Impact Sensor — First Row, B-Pillar in this section. GO to V54.
For first row passenger side impact sensor (F_P_ SEN) with a mounting/communications (COMM) fault, GO to V12.
For first row passenger side impact sensor (F_P_ SEN) with an internal (INT) fault, INSTALL a new first row passenger side impact sensor. REFER to Side Impact Sensor — First Row, B-Pillar in this section. GO to V54.
For second row driver side impact sensor (D_2_SEN) with a mounting/communication (COMM) fault, GO to V22.
For second row driver side impact sensor (D_2_ SEN) with an internal (INT) fault, INSTALL a new second row driver side impact sensor. REFER to Side Impact Sensor — Second Row, C-Pillar in this section. GO to V54.
For second row passenger side impact sensor (P_2_ SEN) with a mounting /communications (COMM) fault, GO to V32.
For second row passenger side impact sensor (P_2_SEN) with an internal (INT) fault, INSTALL a new second row passenger side impact sensor. REFER to Side Impact Sensor — Second Row, C-Pillar in this section. GO to V54.
For front impact severity sensor (FNT_SEN) with a mounting/communications (COMM) fault, GO to V42.
For front impact severity sensor (FNT_SEN) with an internal fault (INT) fault, INSTALL a new front impact severity sensor. REFER to Front Impact Severity Sensor — Vehicles Built 03/2002 Onward in this section. GO to V54.
No
This is an intermittent fault. The fault condition is not present at this time. GO to V53. Do these first and let me know .and then we go on to the next step Good Luck
Answer -
Erik this is only avabile thru ford only. V42 INSPECT THE FRONT IMPACT SEVERITY SENSOR MOUNTING, MOUNTING BRACKET AND MOUNTING SURFACE
Depower the system. Refer to Supplemental Restraint System (SRS) Depowering and Repowering in this section.
Inspect the front impact severity sensor mounting and make sure that the retaining bolts are fully seated and tightened correctly.
Remove the front impact severity sensor. Refer to Front Impact Severity Sensor — Vehicles Built 03/2002 Onward.
Visually inspect the front impact severity sensor, mounting bracket and mounting surface for damage, corrosion or dirt.
Was a significant amount of corrosion or dirt found, the front impact severity sensor mounting bracket attached to the mounting surface incorrectly or were the front impact severity sensor bolts not fully seated and tightened correctly?
Yes
CLEAN, TIGHTEN bolts or REPAIR the mounting surface as necessary. REINSTALL the front impact severity sensor. GO to V54.
No
GO to V43.
