TAILIEUCHUNG - Climate control systems and air conditioning in automotive: Part 2

Continued part 1, part 2 of Climate control systems and air conditioning in automotive present the content: diagnostics and troubleshooting, initial vehicle inspection, pressure gauge readings and cycle testing; service and repair, refrigerant recovery, recycle and charging, servicing precautions, system flushing; the environment, global warming, the ozone layer; legislation, historical perspective, us perspective. | Climate control systems and air conditioning in automotive: Part 2 4 Diagnostics and troubleshooting The aim of this chapter is to: ● Enable the reader to understand the range of techniques that can be used in diagnosing faults which affect system performance. Initial vehicle inspection The initial vehicle inspection is not a checklist. Information from the customer on the symp- toms, vehicle history and conditions upon which the fault occurs will allow the technician to be selective. The technician should first try to gather as much information as possible and assess if the symptom is normal behaviour (water dripping from underneath the vehicle) or not. The technician should then assess if the environment in which the fault occurs can be replicated. For example, a fault which occurs when the vehicle has been idle for 2 days cannot be repli- cated the same afternoon the vehicle has been delivered. The correct conditions (temperature, load conditions) must be available to enable accurate fault detection. If conditions are not right then the customer must be aware that an initial diagnostic period will be allocated to the vehicle to carry out a range of tests allowing a number of possible causes to be verified. The technician should then ensure that they have access to all information required from the customer and for the vehicle. This includes fault finding charts, wiring diagrams, technical service data, diagnostic procedures, technical service bulletins etc. This information may be as simple as a radio code in case the power to the vehicle is interrupted to ensuring the customer has access to a fault code pod (card) which allows access to any fault codes held within the sys- tem (see Chapter 3, sections , and for examples of information). Manufacturers also have software-based fault diagnostic procedures which direct the technician through guided procedures. Technical helplines are also available. .
