MAY 2021 AFTERMARKET 37 standard A/C service to the next level. Due to the complexity and ongoing connectivity of today’s vehicle systems, the workshops’ way of working when servicing and performing repairs changes continuously. By means of the versatile ESI[tronic] 2.0 Online features and the connectivity via Bosch Connected Repair, Bosch diagnostic solutions expand the workshop’s range of services while easing maintenance and repair procedures. Using Bosch Connected Repair, a vehicle driving up for its maintenance or repair can be identified by its vehicle identification number (VIN). This application eases entering vehicle and customer data. All information is entered just once. It is lastingly stored in a workshop- internal database and can be accessed and reused at any time. At the reception check via Bosch KTS, the vehicle condition is analysed and possible faults are listed. The fault memory monitors the components connected to the air conditioning system via control units. In this manner, all of the vehicle’s fault memories are checked while allowing to save the results. Besides reading out actual values of the components installed – e.g. the values of the temperature sensor –the air conditioning system pressures can also be analysed. The functionality of the control panel is checked as well. Moreover, the ECU diagnosis includes different functional tests concerning the air conditioning system. For this purpose, components such as the compressor, the fan or even the air distributor can be operated and checked via KTS device. The nominal values and filling quantity are specified at the database of the A/C service unit and at ESI[tronic] 2.0 Online. In addition, mechanics can also use experience-based repair (EBR). It comprises the most common A/C faults compiled by vehicle types. EBR is a database listing known faults and the respective solutions or remedies. For additional information and regarding specific issues, users can access technical documents such as circuit diagrams, test values, installation positions, information on spare parts and additional support using ESI[tronic]2.0 Online. The diagnosis includes routines to check proper A/C functionality. The results are documented at a protocol. Bosch Connected Repair provides yet another unusual feature. It connects the test equipment such as ACS units, KTS and ESI[tronic] 2.0 Online with one another. That is, once the vehicle has been identified, test protocols and repair procedures are stored centrally in a paperless form. Even product information such as the order number of suitable cabin filters, installation instructions and test routines in line with the manufacturer specifications can be accessed easily for each vehicle. Using a WLAN network and Connected Repair, workshops are able to connect their workshop equipment to one another. Thanks to this data workflow, they can increase both speed and efficiency of their work and save the results. This interaction between Bosch ACS units and diagnostic solutions allows professional and competent servicing of automotive air conditioning systems. Connected Repair Before using the test equipment, user and vehicle data must be entered. Connected Repair prevents the need to enter the same data twice – right from the first check-inat the workshop. Connected Repair logs any tasks performed and saves the results obtained at a central database. It also keeps a record for each vehicle. Pictures can be added via smartphone. Modern air conditioning service is much more than just standard routines... ” ACS 663 ACS 563 A/C servicing also includes cabin filter Replacement
