Why is air bag indicator light on when engine is started?

Why would the dealer unhook the air bag light ? Turn the key to the on position ,is the air bag light lit ? That would be ******* for the deal to disable air bag light . An besides ,there is no buzzer for a non working airbag light. So take it back to the dealer.

Air Bag Warning Indicator The instrument cluster is hardwired to the restraint control module (RCM). If an air bag system concern is detected, a diagnostic trouble code (DTC) is logged, and the RCM provides a ground path to the instrument cluster, turning on the air bag indicator

If there is a problem with the airbag system a DTC- diagnostic trouble code would set

Restraints Control Module Diagnostic Trouble Code (DTC) Index DTC Description Action B1869 Lamp Air Bag Warning Indicator Circuit Open Go To Pinpoint Test N . B1870 Lamp Air Bag Warning Indicator Circuit Short to Battery Go To Pinpoint Test N . All other DTCs - REFER to Section 419-10 .

There is actually a recall on the toyotas for the air bag light coming on. Go to the dealer or call them and run your vehicle id number to see if the recall applies to you. If you are in an accident there is a good change the airbag will not work.

THE SRS means Air bag sensor and trigger ..

Simply put the SRS light tells you that the sensor cant connect to the trigger of your airbag namely the one locate in the steering wheel. This is beacause of a device known as a clock spring located in the steering. Its moves like a clock and allows the sensor and bag to get connection but sometimes the coil wires get broken.

To fix this take it to a SHOP.
reasons for that.
1.) A DEPLOYED AIR BAG WILL KILL YOU
2.) WITHOUT THE PROPER KNOWLEDGE YOU WILL DEPLOY THE AIR BAG
3.) EQUIPMENT IS EXPENSIVE

the fix involves. (REMOVE BATTERY)
1.) remove the steering wheel using the lock bolt and key
2.) unblot and remove then unlock the clock spring
3.) replace,
4.) recalibrate and reset spring
5.) reset error codes
6.) reassemble
7.) reset error codes.

You just need to turn it off again. You created a false trigger of the light. You may have to have dealer do it with scan tool.


Prove Out Procedure
Turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules or restraint system diagnostic tools installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:

• fail to light.
• remain lit continuously.
• flash.

The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the RUN position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.
----------------------------------------------------------- Restraints Control Module (RCM)
The restraints control module (RCM) performs the following functions:

• signals the inflators to deploy the air bags in the event of a deployable crash.
• monitors the air bag supplemental restraint system (SRS) for faults.
• illuminates the air bag indicator if a fault is detected.
• flashes the air bag indicator to indicate the lamp fault code (LFC) detected.
• communicates through the data link connector (DLC) the current or historical diagnostic trouble codes (DTCs).
• signals the generic electronic module (GEM) to activate a chime if the air bag indicator is not available and another SRS fault exists.

NOTE: The safing sensor is internal to the RCM and is not repaired separately.
The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster.
When the ignition is cycled (turned off and then on), the air bag indicator will begin its prove out sequence. During prove out the air bag indicator will illuminate for six seconds, go off for two seconds and then, if a system fault exists, flash the two-digit LFC. The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the DLC, using a scan tool. If the air bag indicator does not function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair.
LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed. After that fault has been corrected, the next highest priority fault will be displayed.
The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that deployment is required. The backup power supply will deplete its stored energy approximately one minute after the battery ground cable is disconnected.
Electrical System
The electrical system that supports the air bag supplemental restraint system (SRS):

• is powered from the battery through the ignition circuit.
• provides the electrical path from the restraints control module (RCM) to the air bag modules.
• provides the electrical path from the RCM to the air bag indicator.
• provides the electrical path from the RCM to the data link connector (DLC).
• provides the electrical path from the RCM to the generic electronic module (GEM).

There are a few things that can cause this, either the air bag itself going bad, or an airbag sending unit or brain going bad,

air bag light stays on

Yes, it's called a lamp fault code.

9 is not familiar to me. Call dealer service department and ask them what code means.

Here are codes for a 94 Aerostar. I don't have 91 Sable. Sorry.

Check the Air Bag Indicator Light. When you turn the car on it should stay on for 6 seconds and then turn itself off. If a fault is detected in the system operation check, the indicator light will either fail to light, stay on continuously or flash. The flashing may not start until up to 30 seconds after the initial systems check.

If there is a fault in the system AND the air bag indicator light fails to light then an audible tone will alert you- it will be a set of 5 chimes (bells/beeps) five times in a row.

Have the Air Bag serviced and the indicator light bulb changed. Since the dash will be off in order to change the bulb, I would have all of the other dash lights changed at the same time. If one goes out, others will surely follow.

Good luck!

Passenger Air Bag Deactivation (PAD) Switch
The passenger air bag deactivation (PAD) switch:

• is located on the instrument panel to the right of the climate controls.
• contains a light emitting diode (LED) that indicates when the PAD switch is activated (passenger air bag disabled).
• allows the passenger air bag deployment circuit to be disabled using the ignition key.
• should be used whenever a child safety seat is being used in the front passenger seating position.

Active Commands
This command allows the technician to verify operation of the air bag indicator, passenger air bag deactivation (PAD) lamp and chime. When the air bag output command is executed, the indicator, the PAD lamp, chime and the chime are activated simultaneously for approximately four seconds. All devices are deactivated automatically.

The Check light is on because one of the sensors in the system is not being read properly by the vehicle ECU. You need to take it to someone & have a scan tool hooked up to it to extract the
DTC(s) that may be stored. Please be advised that a loose Fuel Cap will set the Check light for sure.

The Air Bag light does a self-test, and, if no one is in the passenger seat, it turns to the "Off" setting. There is a sensor under the passenger seat that tells the Air Bag ECM this. The light is there to let you know that the pass air bag will not go off, in the event of a collision, and no one is in the pass seat. Saves the inmsurance company money, probably.
