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.

Hi i have just changed steering wheel on fiesta zetec 2003 for a ST150 2005 steering wheel will the air bags and connections be compatable with each other.


. Were did you check for codes ? an what are you checking with ? you need a factory scan tool to check for those type codes ? or the light flashes codes
Lamp Fault Code (LFC)
When the RCM detects a fault, it will cause the air bag indicator to flash a coded sequence called a LFC. The code is one digit. The digit is indicated by a number of flashes with a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indicator will remain lit as long as the key remains in the RUN position. If there are multiple LFCs, each LFC will flash in order of priority.
Each LFC has one or more associated DTC.
  1. Press TRIGGER. The RCM will run the On-Demand Self-Test and display On-Demand DTCs (reflecting hard system concerns) on the screen.

Where is passenger side air bag relay 2007 MKZ


There is no relay for the passenger side air bag . What seams to be the trouble ? There is possibly a code set in the air bag control module .
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants, in addition to that provided by the 3-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles are also equipped with driver and front passenger safety belt retractor pretensioners. These vehicles can also be equipped with optional side air curtains that deploy from the A-pillar to the C-pillar upon a side impact. Vehicles with optional side air curtains are also equipped with seat side air bag modules in the front seats.
Side air curtains deploy from the headliner, protecting the first and second row outboard occupants during a side impact. Seat side air bag modules deploy from the outboard front seat backrest upon a side impact. In addition, a front impact severity sensor is mounted to the lower radiator support, a seat position sensor is mounted to the driver seat and a usage detection switch is added to the front driver and passenger outboard buckles. If equipped with optional side air curtain modules and seat side air bag modules, there are an additional 4 side impact sensors.
Vehicles are also equipped with an occupant classification sensor (OCS) system as part of the front passenger seat. The OCS system includes 2 OCS rails and an OCS module.
Passenger Air Bag Deactivation (PAD) Indicator
The passenger air bag deactivation (PAD) indicator is a visual indicator used to inform the front seat occupants of the passenger air bag deactivation state. The PAD indicator is a stand-alone lamp installed into the vehicle instrument panel in a position visible to each front seat occupant.
The restraints control module (RCM) controls the state of the PAD indicator through a direct hardwire connection, based on information provided by the occupant classification sensor (OCS) system. The PAD indicator is lit to indicate the passenger air bag module is disabled. An exemption to this is when the front passenger seat is determined to be empty and passenger safety belt buckle unbuckled, and therefore indication of a deactivated passenger air bag module is not necessary. In all other cases, the PAD indicator is unlit when the passenger air bag module is enabled.
When the ignition switch is in the ON position, the PAD indicator prove-out period is initiated by the RCM. The RCM briefly activates the PAD indicator to prove-out the indicator function and verify to the front occupants correct functional operation of the PAD indicator.
The PAD indicator will be lit/unlit within 1.0 to 1.5 seconds of a change of state from the OCS system.
When an OCS system fault is present, the RCM defaults the passenger air bag module to the last valid state received from the OCS system until the ignition switch is turned OFF. If the OCS system fault is still present when the ignition switch is turned ON, the RCM defaults the passenger air bag module to enabled regardless of the size of occupant in the front passenger seat. The PAD indicator will be unlit. For information on the OCS system, refer to Occupant Classification Sensor System in this section.
The following table indicates the passenger air bag status and the PAD indicator status based the size of the front outboard passenger occupant.

On my 2006 Chevrolet Aveo the passenger side airbag light is on unless an adult occupies the seat. Can you provide a solution? Thanks, Zaki


Check your owners manual but on many vehicles it will illuminate a light indicating to the driver or occupants that the passenger air bag is off. The air bag module uses sensors in the seat to determine when it is appropriate and safe for the air bags to be used in the event of a collision. This may be normal operation of the restraint system. You'll need to reference the manual to be sure.

The PAD indicator will be lit/unlit within 1.0+0.5 seconds of a change of state from the OCS system or PAD switch.When an OCS system fault is present the SRS defaults the passenger air bag module to enabled regardless of the PAD switch status or the size of the occupant in the front outboard passenger seat. The PAD indicator will be unlit. The cost of PAD SWITCH is near to $85. and yes it’s a dealers part/but some car parts store keeps the compatible PAD SWITCH parts with them.they are not original but compatible.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

The service air bag light is on.


Sometimes the wiring under the passenger seat can become compromised from objects in floor becoming wedged under the seat.May need to be reconnected if possible..Usually if the air bag light remains on , it means the air bag will not engage if needed. Should have the dealer service department check for you.

SRS indicator on the main meter is glowing continously


The SRS stands for Supplemental Restraint System, and it means theres a problem with the cars air bag. That is not something you want to try to diagnose or fix yourself. You can accidentally deploy the air bag, and if youe anywhere near it when it does, you can be very seriously injured. I would recommend taking the car to a good shop that has experience with air bags, to check the system. Good luck.

5 series' of 5 beeps in a row on start up


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!

1999 f150 airbag light stays on after blinking upon start up!


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.
------------------------------------------------------------------------------------------
Prove Out the System
Prove out the system means to turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules 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 tone bursts. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.
----------------------------------------------------------------------------------------
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.
