System Operation Check

1996 Mercury Sable LS, 4D Sedan, 3.0 SSECTION System Operation Check
  1. When checking SRS operation, and upon completion of each diagnostic test, check for faults in SRS. To check system, turn ignition switch to RUN position. If AIR BAG warning light glows for 4-8 seconds and then goes out, SRS is functioning properly and no fault codes exist.
  2. If a fault code is detected in SRS during initial system check, AIR BAG warning light will either fail to light, stay on continuously, or flash a code sequence. If AIR BAG warning light flashes, indicating a fault in system, count number of flashes after fault code has cycled twice. Number of flashes represents a code number used to diagnose SRS. See DIAGNOSIS & TESTINGΒ  .
  3. If a system fault exists and AIR BAG warning light fails to light, an audible tone will be heard, indicating AIR BAG warning light is out and service is required. See TONE GENERATORΒ  under DESCRIPTION & OPERATION.
