  Q: How to Service the Air Bag Control Module for a 2-Door Vehicle on Toyota Echo?

  A:

  Service of the Air Bag Control Module for a 2-Door vehicle begins by taking out the front door scuff plate along with front door opening trim, rear seat cushion, rear seatback, rear seatback hinge, rear Seat Belt, quarter trim, and the retractor part of the front seat outer belt. The first step requires disconnecting the connector from the side Air Bag sensor assembly which must be done with the sensor assembly mounted. Then remove the assembly's three bolts. You must replace the SRS parts with new components during installation because any side Air Bag sensor assembly from a collision should never be reused and sensors should not undergo repairs after a collision. After installing the three bolting system to the side Air Bag sensor assembly keep the torque at 20 N.m (205 kgf.cm, 15 ft.lbf), then attach the connector to the sensor assembly while checking that the proper torque has been achieved. The sensor assembly needs to be replaced by a new one whenever it shows a defect or when it experiences a drop. The SRS wiring must avoid other components and stay free of pinches in its installation. Check to verify that the sensor assembly remains tight after completing sensor installation by performing a shaking action. The last step involves reattaching the retractor part of the front seat outer belt along with quarter trim, rear seat belt, rear seatback hinge, rear seatback, rear seat cushion, front door opening trim and front door scuff plate.

  Q: How to Service the Air Bag Control Module for a 4-Door Vehicle on Toyota Echo?

  A:

  The Air Bag Control Module service for a vehicle with four doors requires one should start by taking off the door scuff plates in front and rear positions then proceed to remove the center pillar lower garnish and finish by disconnecting the front seat outer belt retractor section. Connectors should be disconnected from the side Air Bag sensor assembly while the sensor remains installed but the three bolts need to be removed for assembly removal. Installation requires only new SRS components because parts transferred from other vehicles or sensors used after collisions cannot be accepted. The new side Air Bag sensor assembly needs three bolts installed with 20 N.m or 205 kgf.cm or 15 ft.lbf torque before sensor connector installation. Check that the sensor assembly is tightly mounted and the SRS wiring should have enough space to avoid blocking other parts. Verify the sensor assembly is tight by performing a shaking test before you install the retractor part of the front seat outer belt followed by the center pillar lower garnish and ending with the front and rear door scuff plates.
