Ranger 4WD V6-3.0L VIN U (1997)
Malfunction Lamp / Indicator: Description and Operation
PURPOSE
If system fault is present, the indicator will either fail to light, remain lit continuously or light in a flashing manner.
OPERATION
The air bag indicator will light continuously for approximately six seconds whenever the ignition switch is turned from OFF to RUN position if the
air bag is working properly. The flashing manner may not occur until approximately 30 seconds after the ignition switch has been turned from OFF
to RUN position. This is the time required by the air bag diagnostic monitor to test and verify any and all system faults. If the air bag indicator is
inoperative and supplemental air bag restraint system fault exists, a tone will sound signaling the air bag indicator is inoperative and a system fault
exists.
TONE GENERATOR
PURPOSE
A tone will sound, if the air bag indicator is inoperative and a system fault exists.
OPERATION
The air bag indicator is the prime means of determining supplemental air bag restraint system status. However, if the air bag indicator is
inoperative and a system fault exists, a tone will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be
serviced before further diagnosis and testing can be completed. Unless serviced, the supplemental air bag restraint system may not function
properly in the event of an accident.
