Diagnostics

Vehicles are getting evermore electronically sophisticated and require advanced equipment and high level expertise to be able to identify complex faults. All cars have an engine control unit (ECU) and some have multiple control modules that communicate with each other. The ECU has a memory that stores current & historic faults detected from engine management sensors. The ECU monitors & controls many vehicle and engine functions (e.g. air fuel mixture, engine temperature and vehicle dynamics). The diagnostic equipment communicates with the ECU & other control modules and is able to read registered faults and monitor vehicle operation.

At Kundi Motors we have the most upto date state of the art Diagnostic equipment, and our high-level technical training means we can make sense of baffling fault codes and advise on any necessary repair.

We have a range of diagnostic Equipment that cover most vehicle makes & models and specialist Equipment for BMW & Mercedes. This equipment allows us to communicate with vehicle control modules and access the live data & fault codes stored in memory.

Snap-On Diagnostic Platform: Snap-on is a world leader in the provision of tools to the automotive industry. The platform enables us to diagnose and fault find most makes & models. The tool is upgraded every quarter to the latest software in order for us to handle every challenge that comes into our workshop.

Autologic Diagnostic Platform: Autologic is a specialist platform that provide main dealer level of diagnostics for BMW, Mercedes & VW Audi Group. Autologic is used to diagnose the more difficult of faults; updating & reprogramming of control units and access to a worldwide knowledge base of known problems & solutions.

Kundi Motors has been using computerised diagnostic equipment since the late 1990's and more routinely since the introduction of OBDII in 2001. Over the years we have gained the considerable knowledge & expertise in identifying complex electronic faults and appropriate solutions.

At Kundi Motors we have a structured approach to fault finding & problem resolution. Where a vehicle has fault indication on the dash, we use a diagnostic tool to scan for fault codes and follow this up with manual diagnoses to isolate specific problematic components.

The introduction of OBDII has allowed the process of fault finding to be less trial & error and more systematic. The OBDII standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. The EOBD fault codes consists of five characters: a letter, followed by four numbers. The letter refers to the system being interrogated.The first character identifies the system related to the trouble code. P=Powertrain B=Body C=Chassis U=Undefined. The next character would be a 0 if complies to the EOBD standard. The last three numbers identifies the subsystem.
