Chevrolet Sonic Repair Manual / Body / Restraints / Restraints Control / Multi-Axis Acceleration Sensor Module Programming and Setup

Note:

DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the Multi-axis Acceleration Sensor or Inertia Sensor Module (IMU) is not properly configured with the correct calibration software, the Electronic Brake Control Module will not control all of the vehicle features properly.
Stable battery voltage is critical during configuration. Any fluctuation, spiking, over voltage or loss of voltage will interrupt configuration. Install the EL-49642 SPS Programming Support Tool to maintain system voltage. If not available, connect a fully charged 12?€‰V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including daytime running lights), HVAC, radio, etc.
During the configuration procedure, follow the SPS prompts for the correct ignition switch position.
Clear DTCs after configuration is complete.
