On Board Diagnostics

The OBD (On-Board Diagnostic) connector is a hard-wired communication link to the ECU (Electronic Control Unit) for connected car industry only, through which is allowed access to read and reset a vehicle’s fault codes. In today’s vehicles, there are more various on-board computer modules, dedicated to different tasks throughout the vehicle. Also, the access to that different diagnostic information of the modules is via the diagnostic connector. In most vehicles, there is only one OBD-II connector in the vehicle through which all systems can be diagnosed and programmed.

We provide services in Telematics alongside automotive electronics.

We offer more than just in car Wi-Fi and offer the following features:

  • Built-in GSM, GPS & G-force sensors

  • Security alerts – notification when car starts or is moving

  • Recorded journeys with playback

  • Driver behaviour & fuel efficiency

  • Vehicle status and health reports

  • DPF regen due in X miles, etc.

  • Vehicle status alerts

  • DTCs, battery voltage, seat belts use, etc.

  • Service information

  • Driver smartphone apps

  • Driver feedback (driving style, behaviour and fuel efficiency)

Brief about OBDII Below

OBD-II Diagnostic Connector Pin Layout

Since the introduction of the OBD-II standard, the connector, and the pin-out arrangement are now the identical in all vehicles. Figure 1 shows the standard female 16 pin (2 rows of 8 pins) J1962 interface connector, and assignment.

Some pins are standard and required by all manufacturers while others (Manufacturer Specific) are left to the individual discretion of manufacturers. The communication bus lines are used for data transmission, ISO lines provide data transfer for many vehicles, and the manufacturer specific terminals can be used for any purpose the manufacturer chooses.

OBD Diagnostic Connector Location

Typically OBD-II connector is located on the driver’s side of the passenger compartment, close to the steering wheel or gear-stick center console for easy access by the diagnostic technicians from both, the passenger’s side, as well from outside the vehicle. Unlike OBD-II connector where it’s standardized to be within 0.6 m (24 inch) of the steering wheel area or within reach of the driver, an OBD-I connector may be located in other areas, such as under the hood in engine compartment nearby the brake booster for example.

OBD-II Fault Codes Explained

Fault codes also known as diagnostic trouble codes (DTCs) typically are made up of a letter followed by four numbers, so each code has a total of five characters.

Here is an identification of the used characters:

First Character:
Bxxxx – Body Systems (lighting, airbags, climate control system, etc.)
Cxxxx – Chassis Systems (anti-lock brake system, electronic suspension and steering systems, etc)
Pxxxx – Powertrain Systems (engine, emission and transmission systems)
Uxxxx – Network Communication and Vehicle Integration Systems (controller area network wiring bus and modules, etc)

Second Character:
x0xxx – Standardized ISO/SAE Code
x1xxx – Manufacturer Specific Code
x2xxx – Manufacturer Specific Code or ISO/SAE Code
x3xxx – Manufacturer Specific Code or ISO/SAE Code

Third Character:
xx0xx – Overall System
xx1xx – Secondary Air Injection System
xx2xx – Fuel System
xx3xx – Ignition System
xx4xx – Exhaust Monitoring System
xx5xx – Idle Speed Control or Cruise Control
xx6xx – Input / Output Signal from Control Units
xx7xx – Transmission System
xx8xx – Transmission System
xx9xx – Transmission System

Fourth and Fifth Character:
xxxXX – Refers to the actual component that the ECU has identified with a fault.

Figure 2. OBD-II Code Reader – How to Read Fault Codes

Let’s look at the code P0302 as an example:

• The first character of the code is a letter designation to indicate the general subsystem that sets the code. In this case (P) indicate to powertrain.
• The second numeric character (0) shows that this is a generic (SAE or ISO) code.
• The third numeric character denotes the subsystem affected. In this case, (3) indicates an ignition system misfire.
• The final two numeric characters indicate a code number that identifies a specific fault in a circuit or component, and will often define the type of fault being experienced. In this case, (02) indicates for misfire detected in the 2nd cylinder

ADAS & Autonomous Driving

Shalaka’s Computer Vision and Augmented Reality solution is a combination of software framework and engineering services. The software framework is optimized for embedded hardware that helps implement a wide range of in-car Advanced Driver Assistance Systems (ADAS) and autonomous driving functionality quickly and cost-efficiently.  

Incorporating artificial intelligence, pattern recognition, image processing, real-time signal processing and more, the feature-rich and robust solution encompasses augmented navigation, advanced parking assistance and adaptive cruise control, driver infographics and lane keeping, driver health monitoring, support of low visibility mode and autonomous driving. The framework augments drivers’ visual reality with supplementary objects in real time, and works with various output devices such as head unit displays, digital clusters, head-up and optical head-mounted displays.
