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

Written by



On March 21, ASA and Bosch partnered to present the third webinar, titled “The Right Scan, the Right Way,” in their series on key scan tool procedures.

The webinar focused on using data stream for testing and verifying computer component function before and after a repair, recalibrating vehicle control modules after diagnosis and/or replacement, and choosing and performing special tests for testing and confirming on/off status of various drive train and body control computerized components. 

ASA Vice President Tony Molla welcomed attendees to the third seminar in the five-webinar series and introduced panelists Steve Zack and Pat Pierce of Bosch. Pierce then took over to announce the purpose of the webinar and to begin the training video, taught by Zack. Zack began with advanced scan tool usage and how to use key scan tool procedures for collision and mechanical repair. Recalling what was covered in the first two webinars, Zack mentioned ADAS systems, collision avoidance systems and a variety of sensors, stressing that newer vehicles can have more than 100 modules that need to be evaluated after an accident.

Stressing that this technology will impact shops’ businesses, Zack mentioned three things that shops should have: a quality scan tool, a battery maintainer or high-end battery jump box and copies of OEM position statements. He defined a quality scan tool as an easy-to-use tool with embedded user assisted diagnostics and operational help as well as in-depth software and module coverage. While it’s important to have the OEM position statements handy, it’s imperative that shops implement a pre- and post-repair scan.

Moving into module resets, Zack explained that Bosch’s systems are very simple and demonstrated how to identify your vehicle by starting from the home page. Choose “Special Tests” and designate which module you want to test. As the webinar proceeded, Zack demonstrated how to use Bosch’s scanners to perform special tests on the Chrysler Active Headrest Restraint, the GM Power Window Motor Programming, the Nissan Zero Point Calibration, the Cadillac Yaw Sensor Learn, the Cadillac Steering Wheel Angle Sensor Reset, the Cadillac Steering Wheel Angle Sensor Learn and Ford Battery Replacement Reset.

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.

Next, the webinar covered verifying component function using a scan tool. Begin by identifying your vehicle, then select Data Stream from the homepage. Select the module, and then you can choose all data items or customize to view only certain items. Zack used the data stream to demonstrate how to verify seatbelt function, ignition crank function, wiper motor run/park function, drivers’ window switch function, door open warning function, brake switch function, charging function and headlight function. 

Zack said he hoped that the Webinar Wednesdays hosted by Bosch and ASA are helpful and announced that the fourth webinar in the series, “You’ve Got the Power: Diagnostic Power in Your Hands,” will be held on April 18 at noon CDT. He provided a brief preview of the next webinar before Pierce fielded questions from attendees.
