Code 14 - Front Impact Sensor Shorted To Ground: TestProcedure
WARNING: This page is about a different car, the 1996 Lincoln Mark VIII. However, it is still accessible from the selected car via links, so may be relevant.
- Verify Condition
Turn ignition on. Check for fault codes. If Code 14 is flashing, go to step 2). If Code 14 is not flashing, check connectors, wiring, splices, and crimps for an intermittent problem. DO NOT proceed with diagnostic test until code is flashing. Failure to do so will result in needless replacement of diagnostic monitor. - Check For Shorted Circuit
Deactivate air bag system. See COMPLETE SYSTEM DEACTIVATION . Leave battery cable disconnected. Disconnect diagnostic monitor located behind glove box. Remove plastic locking wedge from diagnostic monitor Gray connector. Set ohmmeter to 200-k/ohm scale or AUTO. Measure resistance between terminal No. 3 and terminal No. 2, 6, 17 and 18 of diagnostic monitor connector. See Figure . If all resistance readings are infinite (open), inspect shorting bar on plastic locking wedge for proper operation. Also, check diagnostic monitor connector terminals for wear or damage. Repair as necessary. After repair is completed, go to CODE 51 . If any resistance is not infinite, go to step 3). - Determine If Sensor Or Wire Is Shorted
Using wiring diagram, locate and disconnect impact sensor whose resistance reading was not infinite in step 2). Measure resistance between ground and Pink/White wire or Pink/Orange wire at sensor connector. If resistance reading is infinite (open), locate and repair short to ground in wiring harness for affected circuits. After repair is completed, go to CODE 51 . If resistance reading is not infinite, replace impact sensor. After repair is completed, go to CODE 51 .
