Installation

  1. Remove the ignition key from the vehicle.
  2. Disconnect the negative battery cable and wait at least three minutes before starting work.
  3. Install the SRSCM using the SRSCM mounting bolts. Tightening torque (SRSCM mounting bolt): 7.8 ~ 9.8 N·m
    • Use new mounting bolts when replacing the SRSCM after a collision.
    • When installing the airbag wiring harness, make sure to install the ground points (C).
  4. Connect the SRSCM wiring harness connector.
  5. Install the rear heater connecting duct.
  6. Install the floor console. (Refer to Body - "Floor Console")
  7. Connect the negative battery cable.
  8. After installing the SRSCM, check that the system operates correctly:
    • Turn the ignition ON; the SRS indicator should illuminate for approximately six seconds, then turn off.
  • The SRSCM detects vehicle rollover. SAB, CAB and BPT may deploy if the SRSCM is shaken up and down or side to side while in the IGN ON state. For this reason, make sure the ignition is OFF before removing the SRSCM from the vehicle.
  • Always perform variant coding when replacing the SRSCM. In addition, perform calibration of the lateral G sensor. (Refer to Restraint - "SRS Control Module")

G-Sensor Calibration

  1. Turn the ignition OFF and connect GDS.
  2. With the ignition ON and the engine OFF, select the vehicle name and the ESC system.
  3. Perform G-sensor calibration.
  4. Perform the "G-Sensor Calibration" procedure using GDS.
  5. Perform the "G-Sensor Calibration" procedure.
