Driver Airbag (DAB) Module and Clock Spring ➤

Passenger Airbag (PAB) Module

- Description The passenger airbag (PAB) is installed inside the crash pad and protects the front passenger in the event of a frontal crash. The SRSCM determines if and when to deploy the PAB.

   

• Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using a specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.

- Components

1. Passenger Air Bag (PAB)


- Removal

1.Disconnect the battery negative cable and wait for at least three minutes before beginning work.

2.Remove the glove box housing.(Refer to Body - "Glove Box Upper Cover Assembly")

3.Disconnect the passenger airbag connector (A) and remove the PAB mounting nuts (B).

4.Remove the crash pad.(Refer to Body - "Main Crash Pad Assembly")

   

• Replace the crash pad which that has been damaged after the PAB has been deployed.

5.Remove the passenger airbag (A) from the crash pad after loosening the mounting bolts.

   

• The removed airbag module should be stored in a clean, dry place with the airbag cushion up.

- Installation

1.Remove the ignition key from the vehicle.

2.Disconnect the battery negative cable from battery and wait for at least three minutes before beginning work.

3.Place the passenger airbag on the crash pad and tighten the passenger airbag mounting bolts.

Tightening torque :3.9 - 5.9 N.m (0.4 - 0.6 kgf.m, 2.9 - 4.4 lb-ft)

4.Install the crash pad.(Refer to Body - "Main Crash Pad Assembly")

5.Connect the passenger airbag harness connector to the SRS main harness connector.

6.Tighten the passenger airbag crash pad mounting nut.

Tightening torque :3.9 - 5.9 N.m (0.4 - 0.6 kgf.m, 2.9 - 4.4 lb-ft)

7.Install the glove box.(Refer to Body - "Crash Pad Center Panel")

8.Connect the battery negative cable.

9.After installing the passenger airbag (PAB), confirm proper system operation :

• Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.

Side Airbag (SAB) Module

- Description The Side Airbags (SAB) are installed inside the front seat and protects the driver and passenger from danger when side crash occurs. The SRSCM determines deployment of side airbag by using Side Impact Sensor (SIS) signal.

   

• Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.

- Components

- Removal

   

• The side airbag cannot be disassembled from the seat back assembly, so replace assembly when replacing the side airbag.

1.Disconnect the battery negative cable and wait for at least 3 minutes before beginning work.

2.Remove the front seat assembly. (Refer to Front Seat - "Front Seat Assembly")

3.Remove the front seat back cover.(Refer to Body - "Front Seat Back Cover")

4.Remove the side airbag from the seatback after loosening the mounting nut.

- Installation

   

• Be sure to install the harness wires not to be pinched or interfered with other parts.

   

• Do not open the lid of the side airbag cover.

• Make sure that the airbag assembly cover is installed properly. Improper installation may prevent the proper deployment.

1.Remove the ignition key from the vehicle.

2.Disconnect the battery negative cable and wait for at least three minutes.

3.Install the side airbag.

4.Install the front seat back cover.(Refer to Body - "Front Seat Back Cover")

5.Install the front seat assembly. (Refer to Body - "Front Seat Assembly")

6.Recline and slide the front seat forward fully, make sure the harness wires are not pinched of interfering with other parts.

7.Reconnect the battery negative cable.

8.After installing the side airbag (SAB), confirm proper system operation:

• Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.

Curtain Airbag (CAB) Module

- Description Curtain airbags are installed inside the headliner (LH and RH) and protect the driver and passenger from danger when side crash occurs. The SRSCM determines deployment of curtain airbag by using side impact sensor (SIS) signal.

   

• Never attempt to measure the circuit resistance of the airbag module even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.

- Components

1. Curtain Air Bag (CAB)


- Removal

1.Disconnect the battery negative cable and wait for at least 3 minutes before beginning work.

2.Remove the roof trim.(Refer to Body - "Roof Trim Assembly")

3. Remove the curtain airbag after disconnecting the curtain airbag harness connector and loosening the mounting bolts.

- Installation

1.Remove the ignition key from the vehicle.

2.Disconnect the battery negative cable and wait for at least three minutes.

3.Tighten the curtain airbag mounting bolts.

Tightening torqueBolt : 7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft)

   

• Never twist the airbag module during installation. If the airbag module is twisted, the airbag module may operate abnormally.

4.Connect the curtain airbag connector.

5.Install the roof trim.(Refer to Body - "Roof Trim Assembly")

6.Reconnect the battery negative cable.

7.After installing the curtain airbag (CAB), confirm proper system operation :

• Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.

Hyundai Accent (HC) (2017 - 2022) Service Manual: Troubleshooting

- Troubleshooting Limp Home Mode Limp Home Mode features a fail-safe function that prevents dangerous situations in the event of a transmission failure. The vehicle will be driven in limp home mode if the transmission malfunctions. In this mode, the transmission operates at a minimal functionality level (fixed shifting, limited shifting, reverse, neutral), making it possible for the vehicle to reach a service center.

Hyundai Accent (HC) (2017 - 2022) Service Manual: CVVT (Continuously Variable Valve Timing) System

- Description Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance through reduction of pumping loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work.
