ASA Partners With Bosch for 3rd Webinar: 'The Right Scan, the Right Way'

Written by


Looking at the Chrysler Active Headrest Restraint, Zack explained that after a collision in which the active headrest restraint has been deployed, the active headrest restraint latch mechanism needs to be released and reset. To reset it, select Occupant Restraint Control (ORC) module, then choose Special Test and Initialize ORC to unlock the active head restraint and allow the headrest to be manually pulled back into position and latched. Then, select continue to initialize function. ORC should only be initialized if the ORC has been replaced.

After replacing a GM power window motor, you must program the new motor by selecting Passenger Door Switch mode, Special Test, Power Window Motor Programming, and then select RPO Option Code. Find the correct option code and hit “Continue” to allow the scan tool to continue programming the window motor.

After removing the front seats or replacing the occupant classification systems module, you must reset the zero point calibration to reset the OCS weight sensors. Select Occupant Detection System module, then Special Tests, and finally Zero Point Function. Make sure the vehicle is level, remove any objects on, under or touching the seat, and minimize vibration in the areas around the seat before hitting start. 

Following a major collision, Cadillac requires Relearn the Yaw Sensor by selecting Multi-Axis Accel Sensor module, followed by Special Tests, then Yaw Rate Sensor Learn. Be sure the vehicle is level, and remove excess weight. Press “Continue,” and then start to begin the Relearn. 

Cadillac Steering Wheel Angle Sensor Reset is needed after an alignment. Select Steering Wheel Angle Sensor module, Special Tests and reset. You will also need to follow this process to complete the Steering Wheel Angle Sensor Learn. In both cases, you will proceed with following the prompts on the scan tool until completion. For a Ford Battery Replacement, go to Body Control/TPMS/PATS module, Special Tests, Battery Monitor System Reset and click “Continue” to apply Battery Monitoring System factory settings back to the vehicle. 

Zack then explored using the scan tool to verify components’ function with special tests used to validate that a special component is operational by using the scan tool to command them. He demonstrated how to verify functional tests for the following components: high beams, step light, turn indicator, stop light, gauge, mirror, lift gate, wiper motor, window motor and bi-directional.
